Results of a Switchover From a Replication Perspective

After a successful switchover, at the data replication level the roles of the primary and secondary volumes have been switched. The pre-switchover RDF1 volumes become the RDF2 volumes. The pre-switchover RDF2 volumes become the RDF1 volumes. Data replication continues from the new RDF1 volumes to the new RDF2 volumes.

The Local-role property of the protection group is also switched regardless of whether the application could be brought online on the new primary cluster as part of the switchover operation. On the cluster on which the protection group had a Local role of Secondary, the Local-role property of the protection group becomes Primary. On the cluster on which the protection group had a Local-role of Primary, the Local-role property of the protection group becomes Secondary.
