1   Description

This instruction describes how to start geographical redundancy in the SAPC. To do this, start Preferred SAPC as Active and Non-Preferred SAPC as Standby.

1.1   Prerequisites

This section provides information of the prerequisites which must be fulfilled before using the procedure.

The following conditions must apply:

• Understand geographical redundancy functionality.
• Both SAPCs are in Initial state.
• Geographical redundancy license is active.

2   Procedure

2.1   Start Preferred as Active

To start the Preferred SAPC as Active, do the following:

1. Connect to the Preferred SAPC and open an Ericsson Command-Line Interface (CLI) session:
2. Navigate to class GeoRedManager object:

   >dn ManagedElement=1,PolicyControlFunction=1,GeoRedManager=1

3. Execute start action:

   (ManagedElement=1,PolicyControlFunction=1,GeoRedManager=1)> start --state Active

   If action was successfully executed, alarms Policy Control, Geographical Redundancy Unable To Reach Peer and DBS, NR, Initial Synchronization Needed raise until the Non-Preferred SAPC is started.

4. Verify the result:

   (ManagedElement=1,PolicyControlFunction=1,GeoRedManager=1)>show

   Note:  

   Since this is a long-running operation, it can be required to enter show command several times until the final operation result is shown in the progress report.

   
   

   When the operation is successfully executed, it shows the following values:

   lastOperationExecuted=START

   lastOperationResult=ACTION_RESULT_OK

   To check the status of the Preferred SAPC, verify that the attribute currentState is Active.

   If an error occurs during the execution of the operation, it shows the following values:

   lastOperationExecuted=START

   lastOperationResult=ACTION_RESULT_NOT_OK

   Attribute lastOperationDetailedInfo shows information about the error. It can take one of these values:

   • Already in Active state
   • Not possible to execute start action from <state> state
   • Parameter state missing
   • Geographical Redundancy without license

2.2   Start Non-Preferred as Standby

To start the Non-Preferred SAPC as Standby, do the following:

1. Connect to the Non-Preferred SAPC and open an Ericsson Command-Line Interface (CLI) session.
2. Navigate to class GeoRedManager object:

   >dn ManagedElement=1,PolicyControlFunction=1,GeoRedManager=1

3. Execute start action:

   (ManagedElement=1,PolicyControlFunction=1,GeoRedManager=1)> start --state Standby

   If action was successfully executed, alarms Policy Control, Geographical Redundancy Unable To Reach Peer and DBS, NR, Initial Synchronization Needed are cleared when both peers are synchronized.

4. Verify the result:

   (ManagedElement=1,PolicyControlFunction=1,GeoRedManager=1)>show

   Note:  

   Since this is a long-running operation, it can be required to enter show command several times until the final operation result is shown in the progress report.

   
   

   When the operation is successfully executed, it shows the following values:

   lastOperationExecuted=START

   lastOperationResult=ACTION_RESULT_OK

   To check the status of the Non-Preferred SAPC, verify that the attribute currentState is Standby.

   If an error occurs during the execution of the operation, it shows the following values:

   lastOperationExecuted=START

   lastOperationResult=ACTION_RESULT_NOT_OK

   Attribute lastOperationDetailedInfo shows information about the error. It can take one of these values:

   • Already in Standby state
   • Not possible to execute start action from <state> state
   • Parameter state missing
