Overview of NetAct troubleshooting
2 Overview of NetAct troubleshootingThis chapter describes the basic principles of troubleshooting, which instructs you how
to proceed when you first detect a fault in your system and begin the troubleshooting
procedure. You should always read this chapter before using any of the recovery proce-
dures presented in this document. It also briefly describes how you can avoid opera-
tional problems.
Begin NetAct troubleshooting by checking the items listed in the following figure. You
should first determine whether the problem only occurs in some network elements or all
network elements. After determining the location of the problem, continue by checking
compatibility and licences. You should proceed by first checking the DNS, LDAP, high-
availability service and the NetAct processes because they affect the functionality of the
entire system. However, the order of the other system checks is random.

Overview of NetAct troubleshooting
The following table lists some of the reasons for operational problems in NetAct:
2.2 Diagnostic tools
Diagnostic tools provide a set of automatic and manual tests for detecting problems,
analysing the configuration and verifying that NetAct is functioning properly. For more
information on using these scripts and detailed descriptions of the tests, see Testing the
System Platform.
2.3 Checking compatibility
After determining the faulty network elements, check that they are compatible with
NetAct. Network elements fall into three categories: fully supported, compatible and not
supported. For an explanation on different compatibility levels, see the following table.
What to do Why to do it
Regularly perform the maintenance tasks
described in NetAct System AdministrationRoutines.
This document describes routine tasks
which a NetAct system administratorshould perform regularly. When mainte-nance tasks are performed regularly,
problems in the system are less likely to
occur.
Install all active NetAct Change Deliveries. Change Deliveries correct detected faults.
To avoid these faults in your system, installall Change Deliveries.
Read the NetAct Technical Notes. Technical Notes inform you of detected
faults and help to avoid possible problems.
Technical Notes also contain a correctionschedule and indicate which notes are still
valid. Technical Notes are available to all
users of NetAct on NOLS athttp://online.portal.nokiasiemensnet-
works.com

For the latest information on supported network element releases and currently support-
ing functions provided for them by NetAct applications, see NetAct and Network
Element Compatibilityon NOLS at http://online.portal.nokiasiemensnetworks.com.
g Authentication is required to get access to NOLS.
2.4 Checking application licences
Before beginning specific troubleshooting tasks, check that a licence exists for the appli-
cation or a certain feature. An entry in the licence file lmdlicmx.datexists for all
licensed applications.NetAct uses two different mechanisms for licensing applications:
1. Installation licence
The installation licence is used during the installation of the corresponding compo-
nent or application. For example, PM Aggregation uses an installation-specific
licence, which means that all software including database components are missing
from the system without the appropriate licence.
2. Run-time licence
Run-time licensing means that all software including database parts are installed
into the system, but the corresponding application or feature cannot be used without
a licence, for example PM-ASCII interfaces and the Alarm Forwarding application.
To check the application licence
1 Log into the Data Server with the username omc.2 In the $OMCPOLICEdirectory, in the file lmdlicmx.dat, check if the string
LTE_ADAPTATION exists.
For more information about the lmdlicmx.dat license file, see lmdlicmx.datinSystem
Platform Technical Reference Guide.
2.5 Contacting Technical Support
When performing troubleshooting, you can turn to Nokia Siemens Networks TechnicalSupport for help if the problem persists and can not be solved by yourself. In such case,
Compatibility Description
Support The defined current (for example, fault management, performance
management or configuration management) or relevant parts of thenew features and related alarms, measurements and parameters ofthe new NE release are supported by NetAct releases or Change
Deliveries on top of releases.
Compatible Different releases of NetAct work together (installing a new version
does not affect existing functionalities) but no new features, alarms or
measurements are supported. You should upgrade NetAct if new func-tionality of a network element is needed.
Not supported Combination of different NetAct releases is impossible. You must
upgrade NetAct or the network element.

reports can be filtered by maintenance regions, therefore alarms in different mainte-
nance regions can be monitored separately using several windows.
Once you receive an alarm in Alarm Monitor, the first task is to locate and identify the
fault or the faulty element for more detailed troubleshooting.
t You can also start the Alarm Monitorapplication from a managed objects pop-up menuand monitor only this particular objects alarms.
Another way to select only one Flexi Multiradio BTS LTE site to be monitored is to drag

To locate and identify the faulty Flexi Multiradio BTS LTE site based on an alarm
1 Start Alarm Monitorfrom Application Manager or from Top-level User Interface.2 Double-click an alarm in Alarm Monitorto open the Alarm Detailsdialog if you
need more detailed information on the alarm.
3 For information on the original reasons behind BTS alarms and on correctiveactions, see the Alarm Manualpages. For instructions, see chapter Referring to
Alarm Manual for alarm specific instructions.
4 Locate the faulty element on Top-level User Interface. Check the alarm lists to findthe element that has generated the alarm. Concentrate first on the alarms generated
by BTS and FTM, and then on the alarms generated by iOMS. Always proceed by
targeting the most severe alarm first. After locating the BTS on Top-level User
Interface, you can start applications and access the BTS Site Manager. .
For instructions on how to navigate through the views on Top-level User Interface,
see Navigating through subviewsin Top-level User Interface Help.
5 You can also drag and drop the BTS into Alarm Monitorto get the basic informationabout it. The information in Alarm Monitortells you the type, ID, name and geo-
graphical location(site address and name) of the faulty Flexi Multiradio BTS LTE
site.
3.4 Checking the event history of the alarming Flexi Multiradio
BTS LTE site
You can get information on alarms originated from Flexi Multiradio BTS LTE site by
referring to the textual information on alarms in Alarm History.
Alarm Historyprovides you with access to all alarms in the faulty Flexi Multiradio BTS
LTE site and allows you to create different queries by defining different search criteria.
Because the amount of alarms can be significant, search criteria help you narrow down
the search. WithAlarm History, you can search for alarm history data in a certain main-
tenance region and make very accurate searches within a precise time frame like one
minute. In addition, you can see other alarms that are related to a certain fault. It also

1 In Top-level User Interface, start Alarm History.2 Select Search Search Criteria.3 Set the managed object search criterion to include the faulty BTS.4 Fill in other search criteria, such as the alarm period, if you want to define your
search even further.
5 Start the search.You may find the root cause of the fault you are investigating by checking the status
of Flexi Multiradio BTS LTE site from a longer time period, such as bad weather con-
ditions, BTS down and so on.
3.5 Checking the status of adjacent Flexi Multiradio BTS LTEs
Once you have located the alarming Flexi Multiradio BTS LTE and analysed the alarm
data, you should check the adjacent BTSs within the same maintenance region to see
if they are affected by something similar. For example, bad weather might cause
problems with microwave links and more than one base station might suffer from this
influence. In addition to adjacent BTSs, problems in a faulty cell may also be caused by
problems in adjacent cells.
Investigate the adjacent Flexi Multiradio BTS LTEs to see if they have generated alarms
that are possibly related to the malfunction.
3.6 Referring to Alarm Manual for alarm-specific instructions
Once the faulty Flexi Multiradio BTS LTE site has been identified, you can take a closer
look at the alarm in theModifiable Alarm Manual application. Alarm Manualcontains
more comprehensive information on alarms and instructions on how to recover from a
failure.
To get more detailed information on the fault
1 Start Alarm Monitor(or Alarm History) if it is not yet open.2 Select the alarm you located earlier.3 Open the Alarm Manual page, check the alarm information and take corrective
actions according to instructions, if possible.
The Alarm Manualpages describe the alarms and diagnostic reports. They provide a
textual explanation of the reason for an alarm and of its impact.
3.7 Troubleshooting Flexi Multiradio BTS LTE modules using
the local management tool
The Flexi Multiradio BTS LTE Site Manager provides you with information on a single
BTS and helps you locate the fault within the BTS. The Site Manager can be used locally
or remotely to see the status and the alarm data of all the modules in a Flexi MultiradioBTS LTE site.

Troubleshooting Flexi Multiradio BTS LTE sites
You will get more information on alarms and modules by selecting different views or gen-
erating history information. The following views are useful in locating and troubleshoot-
ing the BTS and its modules:
The Equipment Viewshows all connected active modules and their state, whichhelps you locate the faulty module. You immediately see the status of the modules
from the LED colour and the number of dot symbols (faulty -red/three dots; degraded
- yellow/two dots; working - green/one dot).
TheAlarm Paneshows the BTS alarms that are generated by itself during a Site
Manager session. It shows the current, most recent alarms.
Alarm History dialogshows all the alarms that have been saved into the BTS. You
can also see alarms other than those saved in the NetAct database.
g BSTechReports are also useful for troubleshooting purposes. They can be fetchedlocally or remotely with the BTS Site Manager.
To troubleshoot the faulty modules using the BTS Site Manager
1 Locate the BTS on the Top-level User Interface.2 Launch BTS Site Manager from the BTSs pop-up menu.3 Locate the faulty modules (in Equipment View) and check the status and the alarm
data.
4 Correct the fault or contact Nokia Siemens Networks Technical Support.
g Because of the correlation techniques in the Flexi Multiradio BTS LTE software, only theoriginal cause of the failure is reported, not the secondary alarms which follow the
original failure.

3.8 Generating reports on Flexi Multiradio BTS LTE perfor-
mance
The NetAct Reporterfunctionality is used for generating PM reports of a certain Flexi
Multiradio BTS LTE site. The Report Builderapplication provides you with methods to
generate ad hoc and pre-made reports on network performance. With Report Builderyou can generate your self-defined reports to visualise the performance data of network
elements in a LTE RAN network based on performance indicators of your choice. You
can also select different time and object level granularities for your reports according to
your needs. For information on how to generate reports with Report Builder, see the
applications help document.
t In addition to analysing single network element with these reports, you can also get aconsistent overview of a region as well as locate problematic areas in the network.
t After a KPI or a report with several KPIs has been created with Report Builder, you caneasily access them via the web by using Report Explorer.

remotely.
To reset the element manually
1 In the Top-level User Interface, locate the Flexi Multiradio BTS LTE site object.2 Open the objects pop-up menu.3 Select Reset BTS.4 If resetting does not help, contact your local Nokia Siemens Networks Technical
Support personnel.
3.10 Initiating recovery actions
With NetAct trouble ticketing solution, you can initiate recovery actions and make surethat the fault is corrected. Trouble ticketing functionality assists in trouble management
by transferring information between NetAct and Trouble Ticket solution. You can create
a trouble ticket based on an alarm or a managed object. You can also create tickets
without any default information.
g Trouble ticket creation is an optional feature in Alarm Monitorand it will only work cor-rectly if a complete trouble ticket system has been fully integrated to NetAct.
To create a trouble ticket based on an alarm
1 In Alarm Monitor, select an alarm (You can also create a trouble ticket from AlarmHistory or from the Top-level User Interface)
2 In the Alarm Monitortool bar, click the Create...icon.The fields in the trouble ticket form are automatically filled in with the information on
the alarm and the alarming object.
3 Edit the information, if needed.4 Click Save.
You can follow the status of the ticket in Alarm Monitor.
