Initiate Switchback

To initiate a switchback

1. Ensure that both Master and Replica servers are available on the network and that the Engine is running.
2. Open the Manager and select the desired scenario from the Scenario pane.
3. [Skip this step if the backward scenario is already running, and move to step 7.]

   If the backward scenario is not running, select the Run button to start the scenario. Arcserve RHA detects that a switchover has occurred, verify its state and configuration, and prompts you to approve the running of the backward scenario.

   Note: The Advanced button opens an additional pane with detailed information about the hosts that participate in the scenario.

4. Click the Run button to start the backward scenario.

   The Run dialog opens.

5. For Microsoft Exchange, select Block Synchronization. For File Server, click File Synchronization and click OK. The resynchronization starts.

   Wait until the resynchronization is completed.

6. Once the resynchronization is completed, you receive the following message in the Event pane: All modifications during synchronization period are replicated. Then, replication from the active server to the standby server starts.

7. Now, you can reverse back the roles between the Master and Replica servers. To reverse the roles, while the backward scenario is running, click the Perform Switchover button, or select the Perform Switchover option from the Tools menu.

   A confirmation message opens.

8. Click Yes on the Perform Switchover confirmation dialog. This procedure initiates a switchback from the original Replica server to the Master server.

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

Now, you can run again the scenario in its original (forward) state.
