Switching Over and Switching Back › Initiate Switchback for a Group

Initiate Switchback for a Group

After a switchover is initiated, whether manually or automatically, at some point, you will want to reverse the server roles and make the original Master the active server again the Replica the standby server. Before you switch back the roles between servers, decide if you want to the data on the original Replica server to overwrite the data on the original Master. If yes, you must first perform a reverse scenario, a backward scenario.

Note: The following steps are the same regardless of server type.

To initiate switchback for a group

1. Ensure that both Master and Replica servers are available on the network and that the Arcserve RHA Engine is running.
2. Open the Manager and select the desired group from the Scenario pane.
3. Perform one of the following:
   • If the scenario is already running, skip directly to Step 4
   • If the scenario is not running, perform these steps and then go to Step 4:
     1. Click Run on the toolbar to start the group.

        Arcserve RHA detects that a switchover has occurred and verifies its state and configuration. After verification completes, the Verification Results dialog appears, listing existing errors and warnings if detected, and prompting you to approve the running of the backward group. If desired, click the Advanced button to open an additional pane with detailed information about the hosts that participate in the group.

     2. Select Block synchronization method from the Run dialog and click OK.

        Resynchronization starts. After resynchronization completes, the message, "All modifications during synchronization period are replicated. Now, replication from the active server to the standby server begins" appears in the Event pane. You can now reverse the roles between the Master and Replica servers.

4. Click Perform Switchover on the toolbar while the scenario is running to reverse the server roles. A confirmation message appears.
5. Click Yes to clear the message and start the switchback process.

   After the switchback is completed, the server roles are reversed back and the scenario automatically stops.

Note: The scenario will continue to run after the switchback when the Reverse Replication Initiation option is defined as Start Automatically.

You may now run the scenario again in its original (forward) state.
