1 Introduction
This instruction concerns alarm handling.
1.1 Alarm Description
The alarm is raised when an installed license cannot be reached.
In a deployment with multiple license key files, the alarm is raised in response to a single missing or corrupted license key file.
The possible alarm causes and fault locations are explained in Table 1.

|---|---|---|---|---|
|
Failing to reach an installed license |
The configured license servers do not respond to the Managed Element (ME) attempt to refresh its license inventory. License information remains unreachable. The ME enters Autonomous mode. |
A missing or corrupted license key file |
License servers |
This fault leads to no service impact during the first 24 hours. If the fault duration exceeds 24 hours, the licensed services are affected (no availability or limited capacity) and alarm License Management, Key File Fault is raised. |

1.2 Prerequisites
This section provides information on the documents, tools, and conditions that apply to the procedure.
1.2.1 Documents
This instruction references the following documents:
- Activate Emergency Unlock Mode
- Data Collection Guideline
- Install License Key File
- License Management
- License Management, Key File Fault
1.2.2 Tools
No tools are required.
1.2.3 Conditions
Before starting this procedure, ensure that the following conditions are met:
- A License Management, Autonomous Mode Activated alarm is raised.
- No ongoing maintenance activities are affecting the network or network elements.
- The user has proper authority to handle configuration management of the network elements.
- Linux® shell access to the System Controllers (SCs).
- Access to an Ericsson Command-Line Interface (ECLI).
2 Procedure
Do the following:
- If there are any network-related alarms on the ME, act on them first.
- Log on to the SC to access a Linux shell, for example:
ssh <user>@<hostname> -p 7022
- Check connectivity with the persistent storage path, for
example:
ls –l /storage/system/software/lm-apr9010503
- Is the persistent storage path accessible?
Yes: Continue with the next step.
No: Consult the next level of maintenance support. Further actions are outside the scope of this instruction.
- Exit the Linux shell:
exit
- Start the ECLI, for example:
ssh <user>@<hostname> -p 22
- Navigate to the KeyFileManagement Managed Object (MO), for example:
>dn ManagedElement=NODE06ST,SystemFunctions=1,Lm=1,KeyFileManagement=1
- View the key file information:
(KeyFileManagement=1)>show -r
The following is an example output:
KeyFileManagement=1 reportProgress actionId=0 actionName="loadLicKeyFile" progressInfo="" progressPercentage=100 result=SUCCESS resultInfo="Successfully loaded the new LKF" state=FINISHED timeActionCompleted="2014-05-13T14:12:34" timeActionStarted="2014-05-13T14:12:34" timeOfLastStatusUpdate="2014-05-13T14:12:34" KeyFileInformation=1 installationTime="2014-05-13T14:12:34" locatable=true productType="SSR 8000" KeyFileInformation=2 installationTime="2014-05-13T14:11:35" locatable=false productType="SASN" KeyFileInformation=3 installationTime="2014-05-13T14:12:15" locatable=true productType="EDA 1500"If locatable=false, then the corresponding license key file is missing or corrupted.
- Change directory to the location where the license key
file is stored on the SC, for example:
cd /storage/system/software/lm-apr9010503/SSR\8000/8887563311a276a54cba15d6359a7f8c
- Note:
- Each license key file is stored in a hashed subdirectory.
The path to the hashed directory contains productType of the license key file, for example:
/storage/system/software/lm-apr9010503/SSR\ 8000/8887563311a276a54cba15d6359a7f8c
The SC detects the restored file within one minute.
For each license key file where locatable=false, transfer the backup license key file to the SC from the backup location.
- Open an SFTP session, for example:
>sftp <user>@<hostname>
Enter remote host password if necessary.
password:
- Navigate to the directory where the backup license key
files are located, for example:
sftp>cd /cluster/licenses
- Copy the backup license key files, for example:
sftp>get license.xml
- Note:
- If backup files are unavailable, order replacement license
key files from the Ericsson software supply organization and install
the files, refer to Install License Key File.
If resolving the issue is expected to take more than 24 hours, Emergency Unlock can be used to prevent the system from entering Locked mode, refer to Activate Emergency Unlock Mode.
The following is an example output when copying a backup license key file from the /cluster/licenses/ folder:
Fetching license.xml
- Exit the SFTP session:
sftp>exit
- Is the alarm cleared?
Yes: Proceed with Step 17.
No: Continue with the next step.
- Perform data collection, refer to Data Collection Guideline.
- Consult the next level of maintenance support. Further actions are outside the scope of this instruction.
- Job is completed.
