When primary site is available or planned maintenance is completed, you can restore the applications from the primary site.

  • Verify that the replication CR or the replication group CR exists at the primary site.
  • Verify that the applications are shutdown at the secondary site before failing back to the primary site.
  • Verify that any data written at the secondary site is copied and resynchronized to the primary site.
  1. For a planned switchover, stop the applications running at the secondary site.
  2. From the primary site, perform a failover of a replication pair. See Managing failover for TrueCopy or Universal Replicator pairs.
  3. If you have configured a replication group, perform a failover of the replication group from the primary site. See Managing failover of a TrueCopy or Universal Replicator copy group.
  4. Create the manifest for the application using PVCs created by Replication Plug-in for Containers at the primary site.
  5. Deploy the applications at the primary site using the prepared manifests, and verify that they are running correctly.
  6. Copy the application data from the primary site to the secondary site.
    1. From the primary site, resynchronize the replication pair. See Resynchronizing a TrueCopy pair or Universal Replicator pair after a failover.
    2. From the primary site, resynchronize the replication group. See Resynchronizing a TrueCopy or Universal Replicator copy group after a failover.
