Manually Recover a Failed Server - Move IP and Switch Computer Name

To manually recover a failed server when both IP and Switch Computer Name Redirection are used

1. Repair any hardware problems that could have caused the switchover issue, if any.
2. Reboot the server without a network connection to prevent IP conflicts.

   The Is Alive check from the Replica to the Master recognizes resource failure, and makes the original Replica the active server.

3. From the Advanced TCP/IP Settings dialog on the Master, remove the additional IP address.
4. From the System Properties dialog, Computer Name tab, change the Computer Name to <ServerName>-RHA. For example, if your server is called "Server 3", rename it to "Server 3-RHA."
5. Assign the server to a temporary workgroup.
6. Restart the computer to enable your changes to take effect. After the reboots completes, reconnect to the network. An error message appears: At least one service failed during system startup. Ignore this message, which it is normal under these circumstances, because the Engine usually runs in a domain account.
7. Rejoin the domain, making sure you use the -RHA name, and reboot again.
8. If the HA scenario is not already running, start the scenario from the Manager by clicking the Run button on the Standard toolbar. If you selected the Run Reverse Replication Scenario after Switchover option, the scenario runs in backward mode, from the original Replica to the original Master. The original Master now acts as the standby server.
9. Wait until the synchronization completes.
10. To return the active role to the Master server, perform a manual switchover by clicking the Perform Switchover button on the Standard toolbar.

    Note: We recommend that you perform the manual switchover outside of normal business hours.
