Peer Persistence switchover operation

A switchover changes the roles of the Peer Persistence groups and reverses the replication direction without impacting the host I/O. The source volume becomes the target, the target volume becomes the source, and the paths between them are reversed from the original configuration. A switchover also makes the LUNs writable from hosts connected to both systems. A switchover is also called a manual transparent failover.

Perform a switchover if service or maintenance must be performed on the source system in the Peer Persistence configuration.

  • Changes the Remote Copy Peer Persistence group Target role of the target systems. The primary group becomes secondary and the secondary group becomes the primary system.

  • Changes the replication direction.

  • Provides the host with read/write access to the volumes on the secondary group.
