Synchronizing Primary and Secondary Instances After Backup and Restore
Synchronizing Primary and Secondary Instances After Backup
and Restore
When you specify that a system backup is restored on a primary instance, the secondary instance is not
updated to the newly restored database that is present on the primary instance.
To make sure the secondary instance is updated, from the secondary instance, you need to request a
hardware replacement to rejoin the restored primary instance. To do this:
Step 1 Deregister the secondary instance from the primary instance.
Step 2 From the web interface of the secondary instance, choose Systems Administration > Operations >
Local Operations > Deployment Operations, then click Deregister from Primary.
Step 3 Choose Systems Administration > Operations > Local Operations > Deployment Operations;
This allows you to perform the hardware replacement of the secondary instance to the primary instance
again
Step 4 Specify the primary hostname or IP address and the admin credential,
Step 5 Select Hardware Replacement and specify the hostname of the secondary instance,
Step 6 Click Register to Primary.
