Reverse resynchronizing mirror and vault relationships

You can use Storage Manager to reestablish a mirror and vault relationship that was previously broken. In a reverse resynchronization operation, the functions of the source and destination volumes are reversed. You can use the destination volume to serve data while you repair or replace the source, update the source, and reestablish the original configuration of the systems.

Before you begin

The source volume must be online.

About this task

    Attention
    The reverse resynchronization operation can cause data loss on the source volume.

  • When you perform reverse resynchronization, the policy of the relationship is set to MirrorAndVault and the schedule is set to None.
