QUESTION 3Using ACSLS, how would you delete a tape pool?

A. Set scr off and delete the poolB. Remove all data tapes and delete the poolC. Delete pool 0 and all empty pools will delete automaticallyD. Remove all volumes from the pool and then delete it


Explanation/Reference:Explanation:Use the delete pool command to delete empty scratch pools. If a pool contains scratch cartridges, you must reassign these cartridges to another pool beforedeleting the first pool. If a scratch cartridge is mounted, it becomes a data cartridge but remains in its scratch pool. Use the set scratch off command to reassign thedata cartridge to the common pool.

QUESTION 4Where are the messages written when a pool gets below the low water mark?

A. acsss_event.logB. pool_error.logC. hardware_event.logD. Doesn't write an error message


Explanation/Reference:Explanation:


low_water_markis the low volume warning threshold. If the scratch cartridge count falls below this threshold, ACSLS logs a warning message in the event log.Valid values are 0 to 231-1. The default is 0.

Note: The ACSLS event log is the first stop for useful information in the event of problems with your library operation. This log contains information about libraryevents, status changes, and errors. All sub-components within ACSLS will report events to the acsss_event.log by sending messages to a process called the eventlogger. The standard event log, which is automatically created when ACSLS is installed, is contained in the file$ACS_HOME/log/acsss_event.log and where $ACS_HOME is usually /export/home/ACSSS/.

QUESTION 5On the SL8500, which is the best option when combining workloads that span more than one rail?

A. using the middle two rails for active enters and ejectsB. using rails that are adjacent to each other within the same SL8500C. using the top rail for extra archival space and any other rail for active dataD. using the top rail for active enters and ejects and any other rail for archival space

Correct Answer: CSection: (none)Explanation

Explanation/Reference:Explanation:If you are not able to assign workloads to a single rail, consider:* Using rails that are adjacent to each other. This provides a shorter distance for the pass-thru operation.* Combining rails vertically rather than horizontally

References:

QUESTION 6Which four statements are true for an SL8500?

A. Partitioned LSMs will not recognize other LSMs, within the library unless they are in the same partition.B. The elevator operationisunder the control of the library controller when CAP operations are issued.C. CAPS can either be shared or dedicated resources for partitions.D. All drives, storage slots, and cartridges within a partition are solely owned by that host or host group.E. While duplicate VOLSERs are supported by the library, ACSLS does not support duplicate VOLSRs unless they are in different partitions and the duplicate

VOLSERs are on different ACLs servers.


Correct Answer: BCDESection: (none)Explanation


B:Elevator operation is under the control of the library controller when CAP operations are issued. The library controller uses the elevators and HandBots to accessthe entire capacity of the CAPs for enters and ejects without regard for the partitions.

Note: Elevators provide vertical pass-thru operations between rails within the same library. Both elevators are located in the front of the library between the frontaccess doors and the Service Safety Door. Each of the four rails share the two elevators.

C: Partitions share the ownership of the CAPs. That is, if one host/partition has CAP A reserved, a different host/partition can have CAP B reserved, or one host/partition can have both CAPs reserved.

D: Elevators, robots, and CAPs are shared resources and--each partition can fully use shared resources for cartridge movement, enter, and eject operations. Alldrives, storage slots and cartridges within a partition are solely owned by that host or host group.

E: Duplicate VOLSERs are supported by the library; however, ACSLS and HSC do not, unless:*The duplicate VOLSERs are in different partitions.* With HSC managed partitions, the duplicate VOLSERs are in different control data sets.* With ACSLS managed partitions, the duplicate VOLSERs are managed by different ACSLS servers.

Note. volume serial numbers (VOLSERs)

QUESTION 8Partitioning allows the SL3000 library to be divided for use by multiple____________.

A. Power SuppliesB. Storage CellsC. HostsD. Drives


Explanation/Reference:Explanation:Library resources (cells, drives, and CAPs) are allocated to a partition for exclusive use by that partition. Storage cells, CAPs, and tape drives allocated to a partitioncan be used only by the hosts assigned to that partition.

Storage cells, CAPs, and drives not allocated to, reserved for or associated with any partition cannot be accessed by any hosts.

References:

QUESTION 9Which three rules apply when the SL3000 library controller automatically adds cells to active storage regions?

A. Cell activation startsinthe left upper rear of the active storage region and moves to the right lower front


B. Cell activation starts with the cells closest to the drives and moves out equally from right to left and top to bottomC. All cells within a column are activated from top to bottom before moving to the next columnD. Columns within a panel are activated from left to right

Correct Answer: ACDSection: (none)Explanation

Explanation/Reference:Explanation:Cell Activation RulesThe library controller uses the following rules when adding cells to active storage regions:* Cell activation starts in the left upper rear of the active storage region and moves to the right lower front.* All cells within a column are activated from top to bottom before moving to the next column.* Columns within a panel are activated from left to right.

QUESTION 12When planning for partitioning the SL8500, which is NOT an assessment question?

A. How many partitions will there be in the library?B. Is this a new or existing installation?C. How many cartridges, free slots, and tape drives are needed for each partition?D. How many CAP slots are needed for each partition?


Explanation/Reference:Explanation:All HandBots and CAPs in the library are shared resources which cannot be assigned exclusively to one partition.

QUESTION 13Which feature contributes most to improved performance and higher library availability with the SL8500?

A. Redundant Control Cards


B. PartitioningC. Redundant CAPsD. Redundant Robots

Correct Answer: BSection: (none)Explanation


QUESTION 14When mapping tape application workloads to the SL8500 rails, a maximum of one workload assigned to each rail.

A. TrueB. False


Explanation/Reference:Explanation:The SL8500 is not just another library. Each SL8500 has four separate rails or Library Storage Modules (LSMs) that work together in parallel.

There can also be two robotsoperating concurrently on each rail. This architecture offers extremely flexible and scalable configurations that can simplify automated tape applications. Instead ofdistributing cartridges and tape drives evenly across all the rails, look at it from a business perspective and logically configure each individual rail to meet yourspecific needs and business requirements. Allocate separate tape application workloads to specific LSMs (rails).

QUESTION 15On the SL3000, if you convert two Cartridge Expansion Modules to two Parking Expansion Modules, how many slots will you lose?

A. 312B. 440C. 516D. 620



Explanation/Reference:Explanation:The optional Cartridge Expansion Module (CEM) provides additional storage cell capacity and growth for cartridges only.Each CEM adds up to 620 data cartridge physical storage cells.

Note: The optional Parking Expansion Modules (PEMs) provide additional storage cell capacity and growth, as well as space for a redundant TallBot to be "parked."The parking space makes the three outer-most columns of storage cells on the front and rear walls inaccessible. The inaccessible cells can be left out of themodule, or they can be installed to allow later conversion of the PEM to a CEM. PEMs do not include tape drives. PEMs are only used with the Dual Roboticsfeature, and they are always installed in pairs. They must be the last modules on the right and left sides of the library series.

QUESTION 16ACSLS and the database MUST be in what mode to accomplish a restore?

A. Both stoppedB. ACSLS down, database upC. ACSLS up, database downD. Both running


Explanation/Reference:Explanation:To restore the ACSLS database from the default tape device attached to the ACSLS server after a databasefailure, do the following:

kill.acsss

3.Shut down the database:db_command stop

4.Ensure any existing redo log files are available to the database system.

5.


Make sure the most current backup tape is write-protected, then insert it into the tape device.6.Enter the following command:

rdb.acsss

Depending on the nature of the database problem, the utility may prompt you for additional information.

7.Wait for the following prompt:

After performing a successful Oracle database recoveryyou should do a database backup. This will ensure yourability to recover again should you have anotherdatabasefailure. Do you want to do this database backup now?8.Remove the tape from the drive and insert a new backup tape.9.Enter "y"and press Return to start the backup.10.Wait for the backup to complete. Remove the tape from the drive, write protect it, label it with the currentdate, and store it in a safe place.11.To start ACSLS, enter the following command:

QUESTION 19When configuring drives in logical libraries which of the following is false?

A. To assign multiple drives to a logical library, the drives must be located in the same ACS.B. Drives may be shared across multiple logical libraries.C. Both LTO and Enterprise drives may be configured into logical libraries.D. Drives may only be added to logical libraries through the ACSLS GUI.




Note:When partitioning the StorageTek SL8500, SL3000 or SL500 libraries into logical libraries, one can assign volumes and drives to the logical library to enablelibrary consolidation, gain capacity on demand, and allow only the client connected to the logical library to access those volumes and drives.

Note: logical libraryA virtual representation of a physical library. Synonymous with virtual library partition.

QUESTION 20How would you generate a list of the EHY100-WHY299 tapes in the LSM?

A. Log in as acssa, issue a "query vol all", and then a "grep WHY100-299"B. Log in as acssa, issue a "volrpt zs", and then a "grep why1"C. Log in as acssa, enter a "volrpt v why", qand then a "grep WHY100-WHY299"D. Log in as acssa and issue a "volrpt-v WHY100-WHY299"


Explanation/Reference:Explanation:The volrpt utility creates a volume report.-vrestricts the report to the specified volumes (or volume ranges). You can specify a single vol_id, a list of vol_ids separated by blanks, or a volume range indicated byvol_id-vol_id.Use the volrpt utility to create a report of library cartridges, including their physical location, history, attributes, and use.

QUESTION 21Using ACSLS, what are the correct steps to create a pool 5 and add cleaning cartridges to that pool?

A. Define pool 5, set scratch on, and then set clean for volume rangeB. Define pool 5, set scratch off, and then set clean for volume rangeC. Define pool 5 and set clean for volume rangeD. Can't define clean tapes to a specific pool


Explanation/Reference:


Explanation:To define cleaning cartridges to ACSLS:1. Make the CAP ready for entry.See "Entering Cartridges" on page 86 for more information.2. Enter the cleaning cartridges.The cmd_proc displays messages with the cartridge IDs of the cartridges you enter.3. To set the cleaning cartridge attribute:set clean max_usage vol_id | volrangeWhere:max_usage is the number of times a cleaning cartridge is used before ACSLS stops selecting the cartridge to clean cartridges. vol_id | volrange specifies thecleaning cartridge or range of cartridges that you entered in Step 2.

Note 1: The set clean command sets cleaning cartridge attributes.Formatset clean max_usage | off vol_id | volrange

Optionsmax_usage | offspecifies the number of times a cleaning cartridge is used before ACSLS stops selecting the cartridge to clean drives. off specifies that ACSLS will not select thecartridge and redefines the cartridge as a data cartridge.

Note: Use the set clean command to set the number of times ACSLS will select a cleaning cartridge. You also use set clean to set a cartridge's cleaning cartridgeattribute off, which you do if you have incorrectly defined a data cartridge as a cleaning cartridge.

For two-thirds of a DEM, you would install two ThirdDEM. For all of a DEM, you could install three ThirdDEMs or one FullDEM.

QUESTION 27Which statement best describes the background audit process that the SL8500 library performs?

A. The library background audit updates the entire cartridge database during robotic operations ACSLS and HSC cartridge audit requests will be processed first,and then the library will satisfy the background audit.

B. The library will process all audits in the background or the library, never interfering with the mount or dismount requests. This audit will update the entirecartridge database during robotic operations.

C. A background audit updates the entire cartridge database in between robotic operations. If a particular cartridge has a request pending and that cartridge hasnot been audited, the SL8500 will audit the cartridge first and satisfy the request.

D. A background audit updates the entire cartridge database both during and in between robotic operations. ACSLS and HSC cartridge audit requests will beprocessed first, and then the library will satisfy the background audit.

Correct Answer: C


Section: (none)Explanation

Explanation/Reference:Explanation:If an audit must be done after the failover, it is done in the background, while other jobs are processed. As a result, you may notice that library operations takeslightly longer to perform until the audit is complete. In addition, if a particular request requires information about a location that has not yet been audited, thelocation will be audited first, causing a slight delay in processing the request.

Note:Entire library audit. The robot visits all cartridge slots (including the CAPs and drives), catalogs the VOLIDs and locations, and updates the HBC cartridge database.This audit is a background process and so does not interrupt online library operations. View the Cartridge Summary Report for the latest cartridge locations andVOLIDs.

QUESTION 39Which three statements about cap partitioning in the SL3000 are true?

A. CAPs can only be shared by partitions with the same host interface type (FC-SCSLor HLI).B. Whole rotational or AEM CAPs can be allocated for exclusive use by one partition, or they can beshared by multiple partitions.C. All CAPs in a partitioned library are unallocated by default. You use the SLC screens to allocate CAPs as dedicated or shared.D. A portion of a CAP can be allocated to a partition.




A rotational or AEM CAP is a shared library resource, meaning all partitions in the library can use the CAP. However, only one partition at a time can use a CAP.While a partition is using a CAP for enters or ejects, the CAP is reserved to that partition and unavailable to all others. For a partition to reserve a CAP, the CAPmust meet all these conditions:·Be available, meaning not reserved by any other partition ·Be empty·Be closed and locked

QUESTION 46Which four activities are part of evaluating the tape application workloads supported by an SL8500?

A. dedicating rails to separate workloadsB. grouping tape drives by type function and quantityC. managing cartridges for improved performance and archivingD. minimizing elevator and pass-thru activitiesE. mapping CAPS and pass-thru ports to partitions

Correct Answer: ABDSection: (none)Explanation


Explanation/Reference:Explanation:A:Dedicating rails--separating workloads to specific rails

Note:Assign each workload its own tape drives, data tapes, scratch tapes, and free cells. Dedicating separate resources to each workload and configuring theseresources on as few LSMs as possible decreases pass thru activity, minimizes the time to mount tapes, and maximizes library throughput.

B: Grouping tape drives--locating them by function and drive type, with enough drives to support the workload

Note:Application-specific requirements may separate drive-types. Example: placing T9840 access-centric tape drives on one rail, and T10000 capacity-centric tapedrives on another.C:Managing cartridges--moving inactive cartridges to archival LSMs or ejecting them. Maintaining free cells on each rail so cartridges can "float" there on adismount.

D:Minimizing elevator and pass-thru port activity--enabling float and using CAPs intelligently.

Note:Do not try to distribute tape drives across all four rails is usually as this can increase pass- thru activity by the elevator and decrease overall performance ofthe library.

QUESTION 47Which three items does the cartridge database of the SL3000 library controller maintain?

A. Volume IDB. Date EnteredC. Current LocationD. Verified Status

Correct Answer: ACDSection: (none)Explanation

Explanation/Reference:Explanation:An audit is the process of reading and cataloging cartridges within a library, verifying the locations of cartridges, or validating a range of slot locations. The librarycontroller maintains a cartridge database that contains the following information for all the cartridges in the library:* Volume ID (VOLID or volser)* Current location (in library internal address format)


* Verified status (true or false)

QUESTION 49In what manner should libraries be added to SL8500 for nondisruptive growth of a library complex?

A. from left to tight, when facing the front doorsB. from right to left, when facing the front doorsC. from either side, It does not matterD. only from the left


Explanation/Reference:Explanation:Adding SL8500 Libraries to theLeftWhen you add libraries to the left of an existing library complex, you can dynamically upgrade the configuration of the software (ACSLS or HSC). This upgrade must


be done to configure the LSMs, panels, cells, and tape drives in the new libraries.

Note: Capacity for the SL8500 uses Capacity on Demand and RealTime Growth to allow you to instantly increase and activate capacity without disruption.

QUESTION 50What ACLs command would you use to stop the acslm process from accepting new requests?

A. idleB. stop req allC. q requests nowD. requests wait


Explanation/Reference:Explanation:Use this procedure to suspend request processing by putting ACSLS in the idle state. Typically, this procedure is used before shutting down ACSLS, but you canalso use it to temporarily stop ACSLS request processing.To idle ACSLS, do the following:1. From a cmd_proc, enter the following command:idleACSLS processes all current requests, rejects all new requests, and goes into the idle state.The following message appears when ACSLS request processing stops.ACSLM Request Processing Stopped: Success.
