Switching Over and Switching Back › Initiate Switchover

Initiate Switchover

If you chose to initiate switchover automatically, after the Master is considered to be down, CA ARCserve HA automatically tries to restore the services and databases on it to their active state. First, CA ARCserve HA tries to restart the SQL services that it previously checked. If the services are running, it then tries to bring the relevant database’s online. If all attempts failed, CA ARCserve HA initiates a switchover. These attempts to restore the services and databases are not performed if the switchover is initiated manually.

To initiate manual switchover

1. Open the Manager and select the desired scenario from the Scenario pane. Verify it is running.
2. Click on the Perform Switchover button, or select from the Tools menu the Perform Switchover option:

   A confirmation message appears.

3. Click OK on the Perform Switchover confirmation message. This procedure initiates a switchover from the Master server to the Replica server:

   Detailed information about the switchover processes is located in the Events pane during switchover.

4. After the switchover is completed the scenario stops:

   Note: The only case in which the scenario may continue to run after switchover is when automatic reverse replication is defined as Start automatically.

   In the Event pane a message appears, informing you that Switchover completed, and then that the Scenario has stopped.

   Now, the Master becomes the Stand-by server and the Replica becomes active server.
