Steps

1. Connect to the SAPC in which the administrative operation is executed and open an Ericsson Command-Line Interface (CLI) session:
2. Navigate to class GeoRedManager object:
   >dn ManagedElement=1,PolicyControlFunction=1,GeoRedManager=1
3. Execute stop action:
   (ManagedElement=1,PolicyControlFunction=1,GeoRedManager=1)> stop
   If action was successfully executed, data replication stops until start command is executed.
   During this period, DBS, NR, Redundancy Disabled alarm is raised.
   If the other SAPC is in Distributed or Standby state, it changes to Active state.
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=STOP
   lastOperationResult=ACTION_RESULT_OK
   To check the status of the SAPC, verify that the attribute currentState is Halted
   If an error occurs during the execution of the operation, it shows the following values:
   lastOperationExecuted=STOP
   lastOperationResult=ACTION_RESULT_NOT_OK
   Attribute lastOperationDetailedInfo shows information about the error. It can take one of these values:

   • Already in Halted state

   • Not possible to execute stop action from <state> state

Steps

1. Configure Active SAPC as Preferred and Halted SAPC as Non-Preferred (See Change Preferred Role in Active-Active Geographical Redundancy). This guarantees that the data changes performed during the administrative procedure are not lost.
2. Connect to the Halted SAPC and open an Ericsson Command-Line Interface (CLI) session:
3. Navigate to class GeoRedManager object:
   >dn ManagedElement=1,PolicyControlFunction=1,GeoRedManager=1
4. Execute start action:
   (ManagedElement=1,PolicyControlFunction=1,GeoRedManager=1)> start
   If action was successfully executed, data replication starts and the SAPC synchronizes with the other SAPC.
   DBS, NR, Redundancy Disabled alarm is cleared.
5. Verify the result of the action:
   (ManagedElement=1,PolicyControlFunction=1,GeoRedManager=1)> show
   When the operation is successfully executed, it shows the following values:
   lastOperationExecuted=START
   lastOperationResult=ACTION_RESULT_OK
   To check the status of the SAPC, verify that the attribute currentState is not Halted.
   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:

   • Not possible to execute start action from <state> state

   • Not possible to execute start action with parameter <parameter> in Active-Active Geographical Redundancy

   • Not possible to execute start action from HALTED state because the SAPC is configured as Preferred
