1 Overview of DD Management

Center

DD Management Center is a Graphical User Interface (GUI)-based product that provides enterprise-wide monitoring of up to 75 Data Domain systems, their configured MTrees and replication contexts (which are referred to hereafter as managed objects).

DD Management Center provides current and historical data about these managed objects, and with subject presentation ranging from site-wide summaries to drill-down detail for a selected object.

DD Management Center is installed and runs on a VMware system (as described in the Data Domain Management Center Initial Configuration Guide). It is released separately from the DD OS software and hardware releases.

DD Management Center can monitor all Data Domain platforms, with the exception of Global Deduplication Array (GDA) systems. DD Management Center can monitor systems running DD OS version 5.0 or later, with slightly lesser functionality for 5.0 and 5.1 systems.

DD Management Station Capabilities

DD Management Center is a Rich Internet Application comprised of a set of browser-based pages that allow you to monitor managed objects.

DD Management Center can be used to:

• monitor the health and operation of managed objects on a user-defined dashboard


• display site-wide storage capacity, showing aggregated usage totals

• graph current and historical data about space usage, data consumption, and daily written data trends

• estimate projected capacity needs based on historical trends, and pinpoint specific dates (both past and future) for usage comparison

• generate usage and performance reports on demand or set up a schedule and email list to facilitate proactive management

• provide users access to DD Management Center as defined by settings you configure for Role Based Access Control (RBAC)

With DD Management Center, you can create custom groupings of systems, organized in ways that are meaningful to you. Applying groups and properties to managed objects customize the content displayed on pages for how objects are monitored and can be used to organize how the objects represent your infrastructure.

DD Management Center also allows some feature configuration for its managed systems, such as managing user access and upgrading the OS of a system or groups of systems.

From DD Management Center, a user can open a DD System Manager session on a managed system to provide full single-system management capabilities. In this way, DD Management Center provides both advanced multiple system management capabilities, and full single system management capabilities.

DD Management Center can process alerts from all of its managed systems, which are viewed from a single list.

How Does DD Management Center Differ from DD System Manager?

The Data Domain System Manager (DD System Manager), the GUI management product that is installed on the Data Domain system, is primarily a single system management tool that provides only limited centralized monitoring and management for up to 20 systems. DD System Manager cannot aggregate the storage space and performance data from multiple systems nor can operational

information among systems be compared, as provided by DD Management Center.

DD Management Center includes its own version of the DD System Manager that can be launched from several views, allowing convenient access to a managed system for further investigation of an issue or to perform configuration, if necessary. See Launching DD System Manager on page 45 for details.


16 Overview of DD Management Center

2 Getting Started

This chapter provides an introduction to DD Management Center and provides basic setup procedures to get the installation up and running.

The topics in this chapter include:

• Logging In and Out of DD Management Center on page 17

• About the DD Management Center Page Elements on page 19

• Licensing DD Management Center on page 33

• Adding Data Domain Systems on page 24

• Working with the Dashboard on page 27

• Managing Properties on page 29

• Managing Groups on page 31

Logging In and Out of DD Management Center

Access to DD Management Center is through a supported browser from a workstation that has network access to the VMware server hosting DD Management Center.

Use one of these browsers for the operating system that is running on your workstation:

• Microsoft Windows —Internet Explorer 8 or 9, Mozilla Firefox 7+, Google Chrome

• Mac OS—Mozilla Firefox 7+, Google Chrome

Note: If DD Management Center is not already installed on the VMware server, refer to the Data Domain Management Center Initial Configuration Guide for instructions.

DD Management Center supports multiple simultaneous users.


Logging In to DD Management Center

To log into DD Management Center:

1. Open a browser and enter the hostname or IP address of DD Management Center.

2. In the login window, enter a user ID and password and press Enter or click Login.

Note: The initial login requires use of the “sysadmin” user ID and default password, which is “changeme.” You will then be prompted to change the sysadmin password. For subsequent logins, other roles and user IDs can be used (see Manage Local User Access to DD Management Center on page 83).

3. On initial login, the Configuration Wizard automatically starts, where you can configure network, license, and system settings for the DD Management Center.

Once you log into DD Management Center, the Dashboard displays showing six default monitoring widgets.

18 Getting Started

About the DD Management Center Page

Elements

The DD Management Center page has the following sectional elements, which will be referred to throughout the remainder of the guide:

Figure 2-1: DD Management Center Page Elements

The DD Management Center page is comprised of the banner panel, navigation panel, work area, and the status bar.

The banner is visible at all times (unless the dashboard is maximized) and provides controls to open the online Help, log

out, and filter for the scope of the active view (this control only displays on monitoring views).

The initial login opens to the Dashboard, containing six monitoring widgets that display in the work area panel.

The navigation panel is organized by modules, and within each module are controls that display the corresponding subject pages in the work area panel. The module titles are Dashboard, Health, Capacity, Replication, Reports, Administration, and Inventory. Descriptions of these views are provided in the chapter About the DD Management Center Interface on page 107.

The status bar shows the active user name and role, evaluation license expiration progress (including a pop-up with a link to register), date, and the alerts notification area (with informational pop-up with a link to the Alerts page).

Standard global control buttons are used to work with the information presented in the main view (sorting, column contents, edit, etc) and are described in the section Global Controls on page 107.

Navigating the DD Management Center Page

There is a sequence for navigating a DD Management Center page to change the focus and scope for the content displayed in the work area. The following example illustrates this, as seen the following graphic, where the numbers correspond to the following steps:

1. Select a module in the navigation panel.

2. Use tabs on the top right to change the content.

20 Getting Started

3. Select toggle buttons at the top right of the page to change the view between a regular tabular view and a “grouped” tabular view.

In the grouped view, the groups created by the user are shown.

Logging Out of DD Management Center

When you want to log out of DD Management Center, click the Logout button on the banner or close the browser window (see Global Controls on page 107 for a picture of the logout control).

Continuing DD Management Center

Configuration

The DD Management Center is running a basic configuration, but many more settings need to be configured to be fully functional. You may need to add licenses for additional DD systems, configure network settings and routing tables, set timezone configuration, and provide access for users. This information is described in Chapter 5, Performing Advanced Configuration on page 51.


You can continue to learn about how to use the features of the DD Management Center by reading the following sections, or skip to Chapter 5, Performing Advanced Configuration on page 51 to configure these settings.

Planning How Managed Objects are

Organized

Before you start to add your Data Domain systems into DD Management Center, it is helpful to plan offline how you want to organize your managed objects (Data Domain systems, MTrees, and Replication Contexts).

Organizing objects is simplified with the aid of groups, which can be further refined with assigned properties.

The grouping paradigm can only be applied to systems, but properties can be applied to systems, MTrees and replication contexts.

Once the groups and properties are created, they can be applied as you add your systems, although it is not required.

When you add systems to DD Management Center, you have the option assigning them to one or more groups and of setting their properties.

A set of system properties are automatically assigned when systems are added (system model, OS, domain name), so only your custom properties need be assigned. If you don’t wish to use groups or properties, you are still able to add systems to DD Management Center.

Creating Groups

Groups are logical containers for Data Domain systems based on a hierarchical structure that an admin user creates. Groups facilitate the management and monitoring of Data Domain systems and are helpful for searches and when used by filters to reduce the scope of objects. Groups can contain other groups and/or systems. A group can belong to only one group, but systems can belong to many groups.

22 Getting Started

Start by creating one or more super-groups at the Groups level, and then add sub-groups and systems as needed.

Note: No Data Domain systems can be created at the Groups node.

1. From the Administration > Groups view, click Add.

2. Enter a name for the group, move systems from the left pane to the right pane, and click OK.

Note: Group hierarchy structures cannot be changed. They must be deleted and re-created to change the structure.

To manage groups, see Managing Groups on page 31.

Creating Properties

Properties are tags you create to identify (classify) systems and the data contained in MTrees and Replication Contexts for searching, filtering, and organizing. Properties can help filter the contents of a tabular listing of objects (such as the Inventory > Systems view) and change the scope of a dashboard widget or generated report. The value of a property can be a string, number, a boolean, or a fixed value string.

A set of default administration properties are applied when systems are added into DD Management Center. You can create and assign other properties as needed. For additional information on properties, see Properties on page 120.

To create properties:

1. From the Administration > Properties view, click where the property will be used (System, MTree, or Replication) and click Add.

2. In the Add Property dialog, enter a name for the property and select its operation type (see Assigning Properties on page 29):

• String—Allows a string of up to 256 characters to be set when the property is assigned. The string is a name, and when assigned, is given a set value. For example, the string may be set to Location, and values may be set to America, China, Japan, etc.


• Boolean—Creates a condition where two values are set (for example, a value of true or false can be set when the property is assigned).

• Fixed Value String—Allows one or more strings (names) to be set when the property is assigned. When Add Multiple Assignments is selected, the property can contain more than one value.

3. Click Add.

The property can then be assigned to an object once systems have been added (see Assigning Properties on page 29).

Adding Data Domain Systems

To manage a Data Domain system, it must first be added to the DD Management Center inventory with the following procedure. A maximum of 75 Data Domain systems can be added to a DD Management Center.

Note: A Data Domain system can only be managed by a single DD Management Center. If an attempt is made to add a system to a another DD Management Center, the attempt will fail.

Use this procedure to add (register) Data Domain systems to the DD Management Center. A maximum of 20 systems can be registered in parallel:

1. From the Inventory > Systems view, click Add. Enter the following for the first system, then click Add to continue adding systems (up to 20 systems). Click Register to continue:

• hostname or IP address (required)

• sysadmin password used on the Data Domain system (required)

• inbound and outbound IP address (or hostname) and port settings used by the firewall (optional). If this option is selected, and the port setting is not changed by the user, the default (3009) is used. If modified by the user, a port number must be between 1 and 65535.

24 Getting Started

Note: The default port settings allow the DD Management Center to communicate with the Data Domain system. If the ports have been changed on the firewall or the Data Domain system, they should be updated here as well.

• check certificate information by clicking in the associated cells (optional)

Note: The Subject name in the DD Management Center CA certificate should match the DD Management Center hostname or SSL will fail the host verification. This is required when adding a DD OS 5.0 system since SSL host verification is performed when DD OS 5.0 system sends historical data to the DD Management Center.

2. A status page reports the success and failure of the additions. Mouse over the error indicator (red X) to display error explanations and recommended resolutions (if available). Click Back to correct errors or delete the system. Once there are no errors, click Next to continue.

Note: The Next button is disabled until all errors are corrected.

3. Select checkboxes from the available properties list to assign properties to all systems and click Next.

4. Select checkboxes from available groups list to make all systems members of the selected groups and click Next.

5. Set warning and critical capacity level thresholds for the systems (shown on capacity views and in reports) and click Finish.

Once a Data Domain system is added to DD Management Center, all historical information for the system is copied to DD Management Center, and every 10-15 minutes DD Management Center retrieves operational data and saves it to its database. DD Management Center monitoring tools draw on this data for current and for historical reporting and trend projections.

Changing DD System Configuration

Once a system has been added into the DD Management Center, use the following procedure to change its configured settings:


1. On the Inventory > Settings page, select one or more systems and click Edit.

Note: When more than one system is selected, if different values are configured for the same setting among selected systems, the field will show “Mixed values.” If the value is changed with its Edit link, all systems receive the new value. Controls for undoing the setting and seeing details are also provided.

2. In the Edit System dialog window, change any of the following settings on the appropriate tab (clicking Apply or changing tabs saves the new settings):

Working with the Dashboard

The Dashboard holds widgets that you create from a set of monitoring functions. Widgets can be organized on separate pages using tabs. Widgets can include specific systems or groups of systems and these can be filtered by properties.

Use the Dashboard to quickly check important conditions such as unreachable systems, active alerts, diminishing capacity, and so forth. See Check Dashboard Status Widgets on page 36 for more information about how to perform monitoring.

By default, each user is assigned a Dashboard with one tab, populated by one each of the six supplied widgets, configured to cover all systems that a user can monitor. You can modify, add to, or even delete this default Dashboard tab.

To get started with the dashboard, you can:

• Add Tabs on page 27

• Create Widgets on page 28

Organize the Dashboard with Tabs

Widgets can be organized on separate tabs. A tab with all its widgets can be copied to a new tab and then edited to suit new. A maximum of 7 tabs are supported.

Some uses for tabs can be to organize a set of systems based on group membership, location, OS version, data type, and so forth.

Another suggestion for organizations could be by widget type, for instance, a tab containing Current Health Status widgets for all systems.

Add Tabs

1. On the Dashboard > Monitoring page, click the Configure Tabs control (see Dashboard on page 109 for dashboard control details). and click Add.

2. In the highlighted text field, enter the name for the tab, choose the number of columns on the tab (more columns produce


smaller widgets), and order the placement of the tab across the dashboard using the Move Up or Move Down controls.

3. Click Save.

Create Widgets

To create a widget, use the following procedure. For detailed information on widget functions, see Widget Functions on page 110. Widgets can be filtered using the standard filter primitives such as systems, groups, and properties; see Global Controls on page 107 for details).

1. On the dashboard, create a tab (see Add Tabs on page 27) or navigate to a tab.

2. Click the Add Widget control (see Dashboard on page 109 for details) and enter a name for the widget.

3. Select a widget type from the drop-down list (see Widget Controls on page 112 for details).

Managing Groups

Although group creation and modification can only be performed by the DD Management Center system administrator, all users can apply group designations and see the complete group structure, although RBAC permissions control which systems are displayed for a user.


Any permissions that are applied to a group affect all systems in the group. A lock decoration is added to the groups folder icon when permissions are directly applied to that group.

Use the Administration > Groups page to perform group management:

• Use the Add control to create groups (see Creating Groups on page 22).

• Use the Delete control to remove groups from the group-level organization.

• Use the Edit control to modify the systems within a group or its name.

Note: Groups cannot be dragged and dropped into a different location, they be changed with the Edit function.

Working with Filters

Filters define the scope of systems displaying in a view, narrow a Report’s output, and target monitoring for Dashboard Widgets.

The drop-down on the filter control allows you to select which groups, properties, systems, and rules to use for filtering. When a filter is active, the filter control is present and highlighted in yellow on the window. Filters can be switched on or off using the filter control as a toggle.

3 Monitoring Systems with

DD Management Center

The monitoring tools included in DD Management Center facilitate examining a wide array of operational data from managed Data Domain systems. Once a Data Domain system is added to DD Management Center, all historical information for the system is copied to DD Management Center, and every 10-15 minutes DD Management Center retrieves operational data and saves it to its database. DD Management Center monitoring tools draw on this data for current and for historical reporting and trend projections.

DD Management Center monitoring tools are highly visual—using charts, graphs, and color coding to facilitate meaningful data interpretation and alerting for critical markers.

DD Management Center monitoring tools help you focus on areas of interest. They can show mile-high status checks of all managed systems or groups as well as drill down to check the health or operational history of a single system’s components. For capacity monitoring, you can easily check current operation, historical data, and perform capacity predictions that are based on usage trends.

Using filtering and grouping options, DD Management Center monitoring tools allow you to shape the data presentation so you can focus on just the information you need.

You can generate reports immediately, create a schedule for when reports are generated, and set up an email list interested parties for receiving the reports.

Included in this chapter are the topics:

• Perform Daily Monitoring on page 36

• Capacity Monitoring on page 40


• Replication Monitoring on page 42

• Monitor Status with Reports on page 43

Perform Daily Monitoring

Performing daily monitoring helps to spot any unusual activity before it can become a serious problem.

The following should be performed at least daily to get an overview of systems status:

• Check Dashboard Status Widgets on page 36

• Check Alert Notifications on page 38

• Check Replication Progress on page 38

Check Dashboard Status Widgets

The Dashboard > Monitoring widgets you configured provide an overview of Key Performance Indicators (KPI) for your monitored Data Domain systems.

The graphs, dials, and color-coded alerting on the widgets make it easy to spot system operational anomalies.

The following sections describe what to look for with the various widget functions:

• Check Health Status on page 36

• Check System Capacity on page 37

• Check Replication Progress on page 38

Check Health Status

The Dashboard health status and alerts widgets highlight any systems that are reporting major reachablity or operational problems. If there are problems, the widgets provide drill-down links to system details so you can investigate problem details.

36 Monitoring Systems with DD Management Center

Current Health Status

The Current Health Status widgets highlight unreachable systems and systems having problems with file system and replication operation, alerts, and data transmission protocols. The widgets show All Normal or show a count of systems exhibiting problems.

• Clicking the system count for each category navigates to the Health page, filtered to display the status of only the widget’s systems.

• Clicking the banner for unreachable systems navigates to the Health Status page to show the status of just the unreachable systems.

• The marker for All Normal status has no navigation or drill-down behavior.

Active Alerts

Check the Active Alerts widgets to see a tally of systems with outstanding alerts. The Active Alerts widgets show the unacknowledged alert tally for Emergency, Error, and Warning class alerts using color-coded bar graphs.

• The length of the bar shows the total number of alerts, while color and symbol provide visual clues.

• Clicking on the alert bar navigates to the Alerts page, filtered by the widget’s configured filters and the type of alert category.

Check System Capacity

Check the System Capacity widgets to spot shortfalls in overall managed storage capacity and to monitor managed systems storage usage.

Capacity Overview

Check the Capacity Overview widgets to see if any systems are nearing warning or critical storage capacity levels.

Also, if configured, monitor the projected capacity usage for the upcoming selected interval.


Space Usage

Check the Space Usage widgets to monitor aggregate totals of storage levels for its managed systems. This widget monitors the total storage capacity of all systems (for space that is used and available). Check pre-compressed space usage and compression ratios to verify that deduplication is working as expected.

Check Replication Progress

Check the Replication Status widgets for replication problems and statistics.

Replication Status

This widget highlights replication contexts with performance problems for the widget’s monitored systems. Also, if configured, shows total bytes written and total bytes replicated in the last 24 hours.

Top Systems by Lag

The Top Systems by Replication Lag widget shows systems exhibiting the longest delays in the expected completion time, ranked by longest delay.

Check Alert Notifications

Monitor the Alerts Notification area, located in the lower left of the Status Bar (see DD Management Center Page Elements on page 19 for details) for new, unacknowledged alerts on systems you are authorized to manage.

Note: The alert notification is not constrained by filter settings that are active, that is, it displays notifications of alerts for all system you are authorized to manage.

The New Alerts area shows the current unacknowledged Emergency, Error, and Warning level alerts. Click anywhere on the New Alerts area to display a pop-up reporting the severity, system name, and class of the new alert. Once the pop-up displays, the alerts notification is removed from the Alerts Notification area.


To see the alert details, click the “Show me these alerts” link to open the Health > Alerts page, where the table is filtered to only show the new alerts.

Check Status and Alerts Views

Checking the Health > Status and Health > Alerts views show more detail of any operational problems. See Health on page 112 for details about the pages.

Use the System/Group toggle button on the Health > Status page to toggle page content.

On the Health Status page, if a system is unreachable, the last known state of the LED flashes for all other columns. (This doesn't apply to disabled or non-licensed systems.)

The status LEDs report:

• Grey LEDs for disabled components

• Red LEDs for errors

• Click the Reachable and Alerts LED to drill down to the Alerts page.

• Click all other LEDs to drill down to the System Details page.

• If the File System is destroyed or disabled, it shows the Red status. As a result of this non-activity, Protocols and Replication are affected and show a Red status as well.

• Non-licensed components are shown by an empty socket

On the Health Alerts page, watch for:

• New or repeating alerts

• Use the Date Range filters to narrow or expand the focus of alert scoping or to go back to a specific point in time.

Note: For additional information on specific alerts, see the Error Message Catalog on the Data Domain Support Portal.


Check the System Details Lightbox

To see detailed highlights of a system’s operation and status, navigate to the Health > Status or Capacity > Utilization page, select a system, and click the System Details button. See System Details Lightbox on page 116 for more information.

Use Graphs to Chart Performance

Check the System Details > Charts page to see historical throughput charting for a system’s components such as the CPU, network, protocols, streams, and so forth. With this tool, you can:

• Graph a system’s resource utilizations (CPU, NIC, VTL ports, and so forth) to identify:

• Whether a system’s resources have been overloaded for significant time periods

• Time frames and systems to consider for a new backup or replication

• If more systems are required

Check System Bandwidth

Check the System Details > Charts > Network chart to see if a system is experiencing bandwidth related bottlenecks. Check how much network bandwidth is being used by systems sharing the same subnet to see if they are using more than expected or allowed by IT departments.

Capacity Monitoring

Use the Capacity pages to view information about the storage utilization by toggling between the Data Domain systems and MTrees being managed by DD Management Center. You can check the current and historical space consumption, as well as estimate projected near-term future storage needs.


Check System Capacity

The Capacity > Utilization page presents storage usage amounts for monitored systems (default) or their MTrees, and these selections can be viewed either by system name or by groups. Each row in the master table (top) shows the usage levels for the managed object, and aggregated totals are presented as the last row of the table. Selecting multiple systems displays their aggregated details.

For more information about the Capacity > Utilization page, see Utilization on page 115.

With the Capacity > Utilization page, you can:

• Monitor the capacity of logically grouped or single systems to track usage and identify the systems that are filling up too quickly

• Identify systems that have used up all their storage space

• Identify systems that have deviated from their norm for capacity consumed, compression ratio etc.

• Identify systems as targets for new back ups, replication, and migrations

• View how much data was written during a timeframe such as a back up cycle, and see how much it was compressed

Check Disk Space Usage Trends

Check the Consumption tab on the Charts and Trends pane (Capacity > Utilization page) for systems that are using disk space faster than planned (higher space usage or lower than expected compression).

The Charts and Graphs pane Space Usage and Consumption pages allow you to see:

• which systems are consuming space at a rate significantly greater or less than their historical norm

• the total capacity, amount consumed, and comp ratio (aggregate) for a group of systems


• the data ingest rate for a group of systems. For example, The total data ingest rate for the last 24 hours

• how many systems are out of space or critically low on space

• how much data was backed up last night (24 hour) and the compression ratio for a group of systems

Use the Capacity > Projected view to:

• Predict when systems will run out of storage space or reach a critically low point

• Determine future capacity needs by projecting current trends

• Determine targets for migration by projecting the systems that are filling up versus the same model systems that will have space available

To learn more about the Capacity > Projected page, see Properties on page 120.

Replication Monitoring

The Replication page allows you to view managed Data Domain system replication configurations by pairs, cascaded replications, and topology charts. You can:

• Monitor the status of contexts that span multiple Data Domain systems using the color-coded status indicators

• Drill down (double-click a pair) to see status and details for the pair on the Cascades view

• Immediately spot any lag time and further check status of a replication context that did not complete within the specified timeframe

• Use the topology charts for a visual check of the operational status of connections, depicted by the color of arrows between systems--mouse over to view details. Use controls to zoom in and out, expand and collapse the contents of configured contexts on systems.

• Assign properties to replication contexts


To learn more about the Replication page, see Replications on page 117.

Monitor Status with Reports

Reports compile information for areas of interest on managed systems, and are generated based on three default template types (capacity, replication, and status). The template configures the report’s content, schedule, and email distribution. For more information about the Reports page, see Reports on page 119.

To work with reports:

• Creating a Report on page 43

• Generate a Report Immediately on page 44

Creating a Report

1. From the Reports > Management page, click Add.

The Create Reports Template dialog displays.

2. Enter a name for the report, select a category from the Type list, and choose one or more sections to include in the report.

4 Managing Data Domain

Systems

Provided in DD Management Center are some tools that can be used to manage Data Domain systems. They include:

• Launching DD System Manager on page 45

• Upgrading Data Domain System Software on page 46

• Creating Access for Users on page 48

Launching DD System Manager

From some DD Management Center pages, there is a link to launch a DD System Manager session for a Data Domain system to perform configuration or troubleshooting. The launched version of DD System Manager actually runs on DD Management Center and not on the Data Domain system, providing centralized and secure administration for multiple Data Domain systems simultaneously.

To initiate a session, click the Launch DD System Manager control from any of the following DD Management Center pages:

• Health > Alerts

• Capacity > Utilization (for the System and MTree views)

• Capacity > Projected

• Replication Details Lighbox

• Replication > Topology (Right-click)

• System Details Lightbox

Note: Be sure the pop-up blocker on your browser is configured to allow pop-ups for DD Management Center.


The DD System Manager session that starts (in a new window) requires no login or logout and provides complete management of the Data Domain system. DD System Manager opens showing the corresponding area from where it was launched (for example, if the launch was from the Alerts view, the Alerts page on the Data Domain system is opened).

The launched DD System Manager looks the same as a native DD System Manager session except it has no navigation panel and no tabs for Reports or Task Logs. The banner shows the DD Management Center name, and for the DD system, name, OS release, model type and role of invoker.

For the launched DD System Manager:

• Users can only launch DD System Manager on systems for which they have an admin role.

• A permission is comprised of a managed object (system or group), a user (local or NIS) and a role.

• Admin role required for replication configuration and IPMI configuration.

• The Security Officer role is not supported

• The inventory of Data Domain systems on DD Management Center are used.

• The Data Domain systems that are shown are based on the effective permissions of the user.

• Only the replication source and destination systems that are registered with the DD Management Center are shown.

• No additional firewall ports need be opened for the session (that is, when a Data Domain system is added to DD Management Center, the same ports are used for the DD System Manager connection).

Upgrading Data Domain System Software

The DD OS on one or more Data Domain system can be upgraded from DD Management Center. A user must have admin rights on the DD System to upgrade and manage packages.

46 Managing Data Domain Systems

The upgrade is comprised of two phases:

• Obtaining the update image from the Data Domain Support Web Site or selecting a previously obtained upgrade image that has been saved locally.

• Performing the upgrade on the Data Domain systems.

Managing Upgrade Packages

You can create a collection of upgrade packages for use in upgrading the DD OS on managed Data Domain systems.

First you will download .rpm images a from the Data Domain Support Portal to a locally accessible drive and then add them to the DD Management Center upgrade packages collection.

Note: The CRC (cyclic redundancy check) file associated with the .rpm file can also be downloaded, which causes DD Management Center to perform a check on the upgrade package before attempting to upgrade.

1. Navigate to the Inventory > Systems view.

2. Select Upgrade > Manage Upgrade Packages.

3. In the Manage Upgrade Packages window:

• The inventory of upgrade packages that are installed on DD Management Center and ready for use are listed in the File area.

• Click the Data Domain Support Portal link to obtain an upgrade package to store locally.

• To upload a package (that has been stored locally) to the DD Management Center inventory, click Add and browse to the local drive to select the package.

• To delete a package, select the image from the inventory list and click Delete (or use the Delete option from the context-menu).


Performing an Upgrade

One or more Data Domain systems can be upgraded using the same DD OS image.

1. Navigate to the Inventory > Systems view.

2. In the top pane, select the target systems for the DD OS upgrade.

Ensure the OS column is visible.

3. From the Upgrade menu, select Upgrade.

4. In the Upgrade Systems window, select the DD OS version with the drop-down list.

The body of the window shows any warnings for Replication dependencies and any version incompatibility errors (a maximum jump of 2 versions is allowed). At this point, systems can be removed wit the Delete control.

5. Click Upgrade to upgrade the selected systems.

If systems are not in an acceptable managed state (unreachable, suspended, upgrading, for example) the upgrade action is unavailable.

Note: Depending on the number of systems selected for upgrade and other factors, the upgrade may take some time. Progress for the upgrade can be tracked on the Health > Jobs page.

Creating Access for Users

To allow a group of users to access DD Management Center:

1. Go to Administration > Settings > Access and select the Local Users tab.

2. Click Create to add users and access groups (NIS and Active Directory) to DD Management Center.

User can now log into DD Management Center, but can’t see any other system. Permissions to view (user role) or administer (admin role) groups and systems need to be added.


3. To add permissions, go to Administration > Permissions and click Add.

For background information about Permissions, see Permissions on page 120.

4. Select where to add the permission:

• Add permissions to Systems—Select this option, and from the list of managed Data Domain systems, click checkboxes of the systems where the permissions will be assigned.

• Add permissions to Groups—Select this option, and from the list of groups, click checkboxes of the groups where the user permissions will be assigned.

5. In the Users area, click + (Add), and select the users from the Select Users dialog box and click Select.

6. Click Add.

New users are given the assigned role (sysadmin or user) for the selected systems or groups.

Tips

To simplify permissions manageability:

• Have very few “admin” users of DD Management Center:

• Have very few “admin” role users of DD Management Center since they can manage ALL DD systems in inventory. In addition, “Admin” role user of DD Management Center configures DD Management Center, configures groups, assigns permissions.

• Configure most other operators’ login into DD Management Center to have “user” role on DD Management Center.

• Use NIS user groups for permission:

Makes it simple to add/remove/modify users. Without changing permission assignment.


• Use DD System Groups for permissions rather than assigning permissions to individual systems.

By assigning permissions at the group level, policy-based permissions can be used with a union model that is applied to the entire group hierarchy.

To simplify permissions manageability...

• Start with lower level permissions top of hierarchy:

• Assign “lower” level permissions towards the root of the Group Hierarchy.

• Assign “higher” level permissions towards the leaf of the Group Hierarchy.

• Uses a union” model, not “override” model. This makes it easy to change permissions at lower levels without affecting the entire hierarchy.

Verify:

• After assigning permissions or changing group membership, verify role by looking at “Effective” role for a system.

Central Administration:

• Use DD Management Center to centrally administer all systems with fewer local accounts on each of the managed systems. Turn off direct GUI access to DD systems that are managed by DD Management Center.

Configuring Routes

Routes determine the path taken to transfer data to and from the localhost (DD Management Center) to another network or host.

DD Management Center does not generate or respond to any of the network routing management protocols (RIP, EGRP/EIGRP, and BGP) in any way. The only routing implemented on DD Management Center is based upon the internal route table, where the administrator may define a specific network or subnet that a physical interface (or interface group) uses.

DD Management Center uses source-based routing, which means that outbound network packets that match the subnet of multiple interfaces will only be routed over the physical interface from which they originated.

Note: The routing for connections initiated from DD Management Center (such as for replication) depend on the source address used for interfaces using the same subnet. To force traffic for a specific interface to a specific destination (even if that interface is on the same subnet as other interfaces), a static routing entry between two systems can be configured and will override source routing.

Configuring routes is described in the following sections:

• View Route Information on page 64

• Set the Default Gateway on page 66

• Create Static Routes on page 66

• Delete Static Routes on page 67

View Route Information

Working with SNMP

To monitor DD Management Center using SNMP, you will need to install the Data Domain MIB in your SNMP Management system. The Data Domain MIB can be obtained by following the instructions in Download the SNMP MIB on page 72. The Data Domain MIB will allow SNMP queries for Data Domain-specific information.

DD Management Center also supports the standard MIB-II so you can also query MIB-II statistics for general data such as network statistics. For full coverage of available data you should utilize both the Data Domain MIB and the standard MIB-II MIB.

DD Management Center supports SNMP V2C and/or SNMP V3. SNMP V3 provides a greater degree of security than V2C by replacing cleartext community strings as a means of authentication with user-based authentication using either MD5 or SHA1. As well, with SNMP V3, user authentication packets can be encrypted and their integrity verified with either DES or AES.

The default port that is open when SNMP is enabled is port 161. Traps are sent out through port 162.

The procedures for working with SNMP include:

• Check SNMP Status and Configuration on page 70

• Enable or Disable SNMP on page 72

• Download the SNMP MIB on page 72

• Configure SNMP Properties on page 72

• Managing SNMP V3 Users on page 72

View Local User Information

Note: The user-authentication module uses Greenwich Mean Time (GMT). Therefore, the expiration dates for disabling the user’s account and the password expiration date should reflect GMT instead of local time.

To view Local User information:

1. Navigate to the Administration > Settings > Access Management > Local Users page.


The Local Users view appears showing the table listing the configured users. Selecting a user populates the Detailed Information area.

The Local Users table lists the following information.

Note: Users who have admin roles can view all users. Users without admin role can view only their own user accounts.

2. Select the user you want to view from the list of users.

Information about the selected user displays in the Detailed Information area.

Item Description

Name The user ID, as added to the system.

Role Possible roles of users based on a set of privileges:

• Admin role: Allows one to administer, that is, configure and monitor, the entire Data Domain system.

• User role: Allows one to monitor Data Domain systems and perform the fastcopy operation.

Status • Active—User access to the account is permitted.

• Disabled—User access to the account is denied because the expiration date for the account has been reached or a locked account’s password has not been renewed. Admin users can disable/enable users with admin or user roles, except SysAdmin User. No users can disable SysAdmin. Security officers can only disable/enable other security officers.

• Locked—User access the account is denied because the password has expired.

Disable Date The date the account is set to be disabled.

Last Login From The location where the user last logged in.

Note: The default password policy can change if the admin user changes them from the Modify Password Policy task. The default values are the initial default password policy values.

User Roles

To enhance security, each user can be assigned a different role. Roles enable you to restrict system access to a set of privileges. Permissions allow an admin access to specific groups and systems, reducing the need to configure every user as a global admin. DD Management Center supports the following roles:

• Admin role: Allows one to administer, that is, configure and monitor, the entire DD Management Center system.

Note: It is recommended that the Admin role be used judiciously and awarded to very few users, as these users will be able to configure DD Management Center as well as have access to all registered Data Domain systems.

Tips for How to Manage Access to

DD Management Center

Since mutual trust is established between the DD Management Center system and the registered Data Domain systems, DD Management Center users also have access to the Data Domain system.

If a user is added with admin level access, that user can also access the Data Domain systems (through ssh or by launching the DD System Manager GUI) and perform admin level operations. Furthermore, an admin level user can invoke an upgrade operation on a registered Data Domain system.

While this is not really a security issue, it should be noted that caution should be taken when adding users to a DD Management


Center system— treat it the same as you would for adding users to a Data Domain system.

The type of access role assigned to individual users or groups of users determine which DD Management Center functions they can use to access data about the managed system and its status.

About Access to DD Management Center Functions

Many DD Management Center pages provide information about the Data Domain systems it manages. Other DD Management Center views provide the ability to configure and manage aspects of the DD Management Center system itself. And some views provide access to the managed Data Domain system.

The ability to execute actions on a DD Management Center view is role-based.

• Access to all functions on a DD Management Center page are available to the DD Management Center Administrator.

• Access that is assigned to a Data Domain system user (called a DD Management Center User) is restricted and only some of the functions on a DD Management Center page are available to a DD Management Center User. When the user is added to the DD Management Center system (either as part of a group or as a stand-alone user), only select areas of the DD Management Center are accessible, based upon the role the user or group is assigned.

• Available roles are the same as those used in DD System Manager:

• admin

• user

• Space Usage—Show summaries of capacity factors (total, used, available, pre-comp, and compression ratio), and alerts for systems at capacity, and warnings for those nearing capacity. Includes a control to navigate to Capacity > Utilization page.

• Replication

• Replication Status—shows a summary of important status factors for replication contexts such as bytes written and replicated in last 24 hours and the longest lag period. Configuration options enable totals for bytes written and bytes replicated in the last 24 hours. Includes a control to navigate to Replication > Overview page.

• Top Systems by Replication Lag—Shows a list of systems exhibiting the longest lag time. There is a configuration option to set the minimum threshold, above which lagging replications are shown. Includes a control to navigate to Replication > Overview page.


Widget Controls

On the widget title bar, controls are included for the following:

Health

The Health module includes pages that provide information on the status and alerts of managed Data Domain systems, as well as the status of jobs running within the DD Management Center.

The Health categories are:

• Status on page 112

• Alerts on page 113

• Jobs on page 114

Status

The Health > Status page displays status information for the Data Domain systems being managed by DD Management Center. The table can be toggled between a systems or group listing. Filtering for narrowing the scope is supported.

Status factors include: whether the system is reachable by DD Management Center, the highest level of current alerts, the File System status, the Replication Context with the most severe status, and the status of the protocols: CIFS, NFS, VTL, and DD Boost.

Note: If the File System is destroyed or disabled, it shows the Red status. As a result of this non-activity, Protocols and Replication are affected and show a Red status as well.

Table A-3: Widget Controls


Edit Widget Opens the Edit Dashboard Widget where you can change the widget name, function, and filter criteria.

Details The global drill-down button on a widget that drills down to the parent page for the widget. For example, for Alerts widgets, the Health > Alerts page is opened.


The table's status reporting is shown via color-coded LEDs, as follows:

Error tallies for systems in the group and for all groups (in the Total field) are shown for a monitored item.

Use the System Details control to view additonal information about a highlighted system. See System Details Lightbox on page 116.

Alerts

The Health > Alerts page displays historical and current alerts that have been generated by managed Data Domain systems and by DD Management Center itself. Many, but not all, alerts remain current until cleared.

Clicking an alert in the table shows alert details in the lower details panel, which includes a link to see even more details about the alert (complete historical information).

Alerts in the table can be filtered by selecting one of the controls on the top right of the view:

• Active Alerts—alerts that are still active on the system(s)

• All Alerts—all alerts (both current and historical) for the system(s)

Status Description

Green Normal; no errors or alerts. No information is shown on a mouse-over.

Yellow Warning alerts; the total number of warning alerts is shown on the cell. Mouse-over provides details and a link to a filtered view on the Health > Alerts page.

Red Problems, unreachable systems, file systems destroyed or disabled, and critical and error alerts—alert totals are shown on the cell, mouse-over provides details and a link to the Health > Alerts page for more information.

Grey Signifies the status is disabled. Disabled is a user-initiated state.

No LED The item is not licensed.


• Date Range—Select a pre-set filter from the drop-down list (All active alerts, last 24 hours, etc.) or create a custom filter.

• Filtering can also be performed on the System Name columns with type-ahead text seaching.

Open the DD System Manager by clicking on an alert in the top pane or with the Launch DD System Manager control, which is enabled when a Data Domain system alert is selected.

Jobs

The Health > Jobs page displays information about jobs (also called tasks) that have been initiated from DD Management Center, including jobs still in progress and jobs that have completed, whether successfully or not. Details of a task, including its subtask status are shown for a selected task in the Details pane.

The progress of a selected In-progress task can be stopped or paused and resumed with the Status controls.

Tasks can run on the DD Management Center alone or can run on the DD Management Center and a Data Domain system. For example, the Report Generation task runs solely on DD Management Center; other tasks, like Upgrade, run mostly on the Data Domain system, but a skeleton process on DD Management Center keeps track of its progress. And still other tasks run mostly on the DD Management Center (like Adding Systems), but have subtasks that run on the Data Domain systems.

Note: Tasks that run on DD System Manager (native to the Data Domain system) are not shown in the Jobs list—only those tasks initiated from DD Management Center are shown.

Additional job-status filtering controls for the table are located at the top left of the page, enabling the inclusion of jobs that have succeeded, failed, or are still in progress. If no selection is active, no jobs are shown.

The list of tasks that display is dependent on the role of the person:

• a person with a User roles on a system or DD Management Center only see the tasks they initiated on that system or DD Management Center


• an Admin on a system or DD Management Center sees all the jobs on that system or DD Management Center.

For detailed information about roles and their management, see Tips for How to Manage Access to DD Management Center on page 96.

Capacity

The Capacity module provides storage usage information for the Data Domain systems and MTrees being managed by DD Management Center. This includes an overview of both current and historical space consumption, as well as an estimate of projected future (12 month) storage needs.

Utilization

The Capacity > Utilization page present storage usage amounts, viewable by Data Domain systems or by MTrees. The System view can be further filtered by arranging the tabular listing by system or group name. The page has controls for examining additional System Details, launching a DD System Manager session, and exporting data to a CSV spreadsheet program for viewing or saving.

In the Capacity > Utilization page, when the Systems filter is selected, space usage amounts are shown for current and the last 24 hour, Pre-comp used, Compression Factor, and Cleanable.

In the Capacity > Utilization page, when the MTrees filter is selected, space usage amounts for Current Pre-Comp Usage, Quota, Quota Available, Quota Used % are shown. The Details Pane Space Usage shows Pre-Comp, Post-Comp, Comp Factor: Last 24 hours, Last Week, Last 5 week Avg.

Aggregated totals of selected objects (Individual or aggregated systems or MTrees) in the master table (top) are shown below in the Space Usage detail pane and graphed in the Charts and Trends pane. Detailed charting is shown for Space Usage, Consumed (Systems only), and Daily Written. Charting controls allow selectable time intervals by manipulating the slider to magnify an interval or clicking a fixed time range (1 day, 7 days, etc).


Note: This guide assumes you are familiar with the capacity terms, as introduced in the DD OS Administration Guide. Refer to that guide or the DD System Manager online help for explanations of the terms.

System Details Lightbox

The System Summary > Details tab shows the selected system’s capacity usage information, summaries of system, replication, and file system status, and critical alerts. The System Summary > Charts tab allows plotting of system CPU resources and throughput of components such as network, streams, protocol, and replication factors. Charting controls allow selectable time intervals by manipulating the slider or clicking a fixed interval (1 day, 7 days, etc).

Projected

The Capacity > Projected page can help you plan future capacity needs:

• Predict when systems will run out of storage space

• Determine future capacity needs by projecting current trends

• Estimate when a system will reach its system-specific warning/critical space usage thresholds

The Capacity > Projected page provides tabular information for listed systems (showing Model, OS Version) and shows space usage amounts (size, used, and free) for past, current, and projected months. There is a graphic that depicts the capacity percentage used, with color coding to show if the status is normal or at warning, and critical threshold levels.

Each date column can be sorted by amounts for Used Space, Free Space, Size and % Used in ascending or descending order.

Right columns show projected space usage, month by month, starting with current space usage

Click on the timeline to select columns to place adjacent in time on the left side to aid with comparison analysis.


Highlighting a system in the list activates controls for examining system details (see System Details Lightbox on page 116) and launching the DD System Manager.

Replications

Replication contexts that are configured among the managed Data Domain systems can be viewed in a variety of ways.

• Pairs on page 117

• Cascades on page 117

• Topology on page 118

• Replication Pair Details Lightbox on page 118

The Replication > Overview page provides a control for examining replication details (see Replication Pair Details Lightbox on page 118), assigning properties (see Assigning Properties on page 29) and exporting tabular data to a CSV file or a map to a PNG file.

Pairs

The Replication Pairs view (default view) is a tabular listing of replication pairs, sorted by either the source system or group name. The tabular columns are user selectable and can show the replication pair’s status, source and destination system names, lag duration and trend, bytes remaining, last sync time, message, type (MTree, collection, or Directory), cascade status, and estimated completion time.

Cascades

The Cascades view is a tabular listing of replication cascades. Expand and collapse a cascade to show or hide their pairs. The tabular columns are user selectable and can show the replication cascade’s status, source and destination, lag trend, bytes remaining, last sync time, messages, type (MTree, collection, or Directory), and estimated completion time.


Topology

The Topology view chart shows system-to-system replication relationships. Controls allow you to expand the view to see an individual pair’s details (such as backup sources) and then collapse to return to default view. Replication relationships are shown with status color-coded directional lines and mousing over the line shows the number of replication pairs and status.

An inset in the main window is a miniature representation of the view that can be manipulated to change the scope of the main view—(it can be moved around to include or exclude systems, enlarged or reduced to change how many systems are shown).

The right pane lists contexts (of highlighted systems in the main view or all contexts is nothing is highlighted), showing the type of context, source and destination systems, status, with a link to additional details. Selecting a context activates the Details control.

Controls to zoom in an out and fit content to window are provided.

Replication Pair Details Lightbox

Selecting a context and the Pair Details button opens the Replication Pair Details lightbox, showing complete information about the status, source and destination systems, settings, and capacity for a replication pair.

The lightbox also and provides charts for plotting replication performance, lag trend, CPU utilization, data written, and replication throughput over time. Each tab shows source and destination system charts, vertically aligned by time. The same metrics are plotted for source and destination systems, allowing comparisons of metrics for both systems at any point in time. A “Common Pairs” radio button limits the comparison to replication pairs that are common to both the source and destination systems.

Controls for assigning properties (see Assigning Properties on page 29) are provided on the lightbox.


Reports

The Reports function allows you to compile specific information about managed systems, based on three default template types (capacity, replication, and status). A wizard configures a template for the report’s content, schedule, and email distribution. A report can be generated from a template ‘ad hoc’ (the template is not saved) or saved (as a template) for generating reports for later use.

Management

Configuring reports to notify recipients with information about managed objects reduces the need for users to log into DD Management Center to obtain status.

Use the Create Report Template wizard, which is started with the Add control, to create the template that is used to generate reports. See Creating a Report on page 43 for details.

Once the report template is created, it is listed in the table where it can be viewed, edited, deleted, renamed, generate a report at will, and downloaded and saved.

Selecting a report in the table shows an historical listing of its generated output in the Details pane. These reports can be viewed, searched, edited and deleted.

Administration

The Administration area is where settings for DD Management Center are managed. The following sections are part of the Administration module:

• Permissions on page 120

• Groups on page 120

• Properties on page 120

• Settings on page 121


Permissions

The Permissions views show what permissions are assigned to users of DD Management Center by assigned role.

Permissions are a triangle that involve three components:

• The managed object (groups or systems)

• The user (local or NIS)

• The DD System Manager role (Administrator, Backup Operator, or User)

The Permissions pages are also used to add, modify, and remove permissions from groups and systems. See Managing Access to the System on page 77 for details.

Each of the views show the users, their assigned role and their effective role.

Groups

The Groups view is where the DD Management Center system administrator organizes sets of systems into a tree. The left pane shows the group hierarchy, and selecting a group in this pane shows its contents (whether subgroups or systems) in the right pane.

One or more groups are created in the Groups folder. Groups can contain nested groups. The structure of the hierarchy or the contents of the groups are changed with the Group controls (Add, Edit, Remove, and Cut/Copy/Paste). See Managing Groups on page 31 for details.

Group creation and modification can only be performed by the DD Management Center system administrator. All users can apply group designations and see the complete group structure, although RBAC permissions control which systems are displayed for a user.

Properties

Properties are tags you create to identify (classify) systems and the data contained in MTrees and Replication Contexts for searching,


filtering, and organizing. Properties can help filter the contents of a tabular listing of objects (such as the Inventory > Systems view) and change the scope of a dashboard widget or generated report. The value of a property can be a string, number, a boolean, or a fixed value string.

Properties are organized and managed by type (System, MTree, and Replication), and selecting a property type displays a catalog of its active properties.

From the type page, properties can be created, modified, deleted, and information about a property’s application is available. See Managing Properties on page 29.

Settings

The Settings view contains pages where you manage and configure settings for the DD Management Center system. To work with settings, see the chapter Performing Advanced Configuration on page 51.

Table A-4: Properties Controls


System property

Denotes a fixed, pre-set property that cannot be edited. Clicking this control shows all its created values in the Values column.The default properties, which cannot be modified, are:• System—Model, OS, domain name

• MTrees—Replicated

• Replication—none assigned by default

User property

Denotes a user-defined property. When selected, can be edited or deleted, and all its created values are shown in the Values column.

Properties details

Opens the Entities window, which shows details about everywhere this property is applied (lists all names of the element (for example, system name), type of property, and assigned value). When opened in the Values column, shows only entities for that value.

Info In the Edit Property window, when clicked, this pop-up shows the type of entity using the property value, its name, and the assigned value.


Inventory

The Inventory view lists the Data Domain systems that are being managed by the DD Management Center. From this view, you can add and remove Data Domain systems, manage their properties, and upgrade their DD OS.

Systems

The Systems view lists the systems being managed by DD Management Center and shows identifying information such as the systems’ OS, model type, location, date added, and DD Management Center user access identities.

Clicking on a system in the list shows additional details for the system. They include:

• Configuration—IP address and port settings for inbound/outgoing firewall, timezone, high and low thresholds for percentage of storage capacity.

• Properties—Shows the applied properties. To assign a value to a property, click Edit, then the Properties tab, and enter the value in the property field. See Managing Properties on page 29 for details.

• Group—Names of groups this system is a member of.

Note: If the table is empty, you need to add systems to the DD Management Center. See Adding Data Domain Systems on page 24.


B Command-Line Interface

DD Management Center has a command-line interface (CLI) that is based on the Data Domain Operating System (DD OS). This chapter describes the DD Management Center-specific features of the CLI.

Note: The main user interface for DD Management Center is the Web-based graphical user interface (GUI). In general, EMC Data Domain recommends that you use the GUI for system management tasks. However, a few system administration tasks for the DD Management Center system itself require that you use the CLI.

This chapter contains the topics:

• Overview of the CLI on page 124

• DD Management Center managed-system Commands on page 125

• DD Management Center task Commands on page 131

• DD OS Commands with Restrictions in DD Management Center on page 137

• Unsupported DD OS Commands on page 138


Overview of the CLI

The DD Management Center CLI consists of three types of commands:

• System management commands (managed-system and task) that perform the basic registration, administration, and job management functions. These commands are unique to DD Management Center. The following sections describe these commands:

• DD Management Center managed-system Commands on page 125

• DD Management Center task Commands on page 131

• DD OS system administration commands that have been extended to support DD Management Center. See DD OS Commands Extended for DD Management Center on page 136.

• DD OS commands that are supported in DD Management Center with limited arguments because a DD Management Center does not directly manage storage. See DD OS Commands with Restrictions in DD Management Center on page 137 for a list of these commands.

Note: The command output for many other DD OS commands omits information that is not applicable to the system’s role as a management virtual appliance rather than a storage appliance.

Many DD OS commands perform tasks for managing storage, and are therefore not useful or supported in DD Management Center. See Unsupported DD OS Commands on page 138 for a list of these commands.

For detailed information about DD OS commands mentioned in this chapter, see the DD OS Command Reference.

124 Command-Line Interface

DD Management Center managed-system

Commands

The DD Management Center managed-system CLI commands let you add and remove systems from management, change their proxy host settings, and suspend, resume, or synchronize data collection.

Note: You can also use the Web interface to perform these actions.

The DD Management Center managed-system CLI commands are:

• managed-system add on page 126

• managed-system delete on page 127

• managed-system resume on page 127

• managed-system set on page 128

• managed-system show on page 129

• managed-system suspend on page 130

• managed-system sync on page 130


managed-system add

managed-system add <hostname> [force] [inbound-proxy <proxy-host> [inbound-proxy-port <proxy-port>]] [outbound-proxy <proxy-host> [outbound-proxy-port <proxy-port>]]

This command adds a Data Domain system into the set of systems that are managed by the current DD Management Center. The command prompts you to:

1. Verify that the certificate obtained from the host is valid.

2. Enter the sysadmin password for the system being added to management.

Note: The proxy options are equivalent to the firewall options in the graphical user interface.

Argument Description

<hostname> The hostname of the system that you want to manage.

force If the system is already being managed by another DD Management Center, the current DD Management Center assumes management of the Data Domain system from the other DD Management Center, and the Data Domain system entry in the other DD Management Center is placed in the unmanaged state. If the system is already being managed and you omit this argument, the command fails.

inbound-proxy <proxy-host> Inbound proxy hostname if the incoming connection from the Data Domain system is through a proxy

inbound-proxy-port <proxy-port>

Inbound proxy port number if the incoming connection from the Data Domain system is through a proxy

outbound-proxy <proxy-host>

Outbound proxy hostname if the connection from the DD Management Center to the Data Domain system is through a proxy

outbound-proxy-port <proxy-port>

Outbound proxy port number if the connection from the DD Management Center to the Data Domain system is through a proxy


For more information about adding systems, see the “Getting Started” chapter of the Data Domain Management Center User Guide.
