Performing a switchover for 3DC PP

A switchover changes the roles and replication direction of the groups from primary to secondary without impacting the host I/O.

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

Prerequisites
  • The three data center Peer Persistence (3DC PP) group has a source and target in synchronous mode.
    TIP:

    HPE SSMC automatically selects the storage system with the synchronous target.

  • The volumes in the source and target are synchronized.

  • All volumes in the source and target have the same WWN.

  • All volumes were exported to the same host from both storage systems.

  • The DR state is Normal.

Procedure
  1. On the HPE SSMC main menu, select Remote Copy Groups under DATA PROTECTION.
  2. In the list pane, select the 3DC PP group, and then select Actions > Switchover.
  3. Click Switchover.
  4. To confirm the switchover operation, select the check box about understanding the implications, and then click Yes, switchover.
