1   Introduction

This document describes how to return Preferred peer back to Active state in a Geographical redundancy scenario, typically after a takeover.

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.
• The SAPC is in Standby state.
• The SAPC is configured as Preferred cluster.
• There are no alarms raised in the SAPC.

2   Procedure

To return Preferred peer back to Active state, do the following:

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

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

3. Execute giveback action:

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

4. Verify the result of the action:

   (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=GIVEBACK

   lastOperationResult=ACTION_RESULT_OK

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

   lastOperationExecuted=GIVEBACK

   lastOperationResult=ACTION_RESULT_NOT_OK

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

   • Not possible to execute giveback action from Non-Preferred node
   • Not possible to execute giveback action from <state> state

   To check the status of the node, verify that the attribute currentState is in Active state.
