1 Description

This instruction describes how to start active-active geographical redundancy in the SAPC.

Prerequisites

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

To start active-active geographical redundancy do the following:

Steps

  1. Connect to one 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
    If action was successfully executed, alarms Policy Control, Geographical Redundancy Unable To Reach Peer and DBS, NR, Initial Synchronization Needed raise until the other 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 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:
    • Not possible to execute start action from <state> state

    • Geographical Redundancy without license

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

  5. Go to the other SAPC and execute the steps 1, 2 ,3 and 4. If step 4 is successfully executed the currentState is Distributed instead of Active.
  6. Verify the state of the SAPC started in first place.
    (ManagedElement=1,PolicyControlFunction=1,GeoRedManager=1)> show
    Verify that the attribute currentState is Distributed.
