Breaking mirror and vault relationships

You can use System Manager to break the mirror and vault relationship if a source volume becomes unavailable and you want client applications to access the data from the destination volume. 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


  1. Click Protection > Relationships.
  2. Select the mirror and vault relationship that you want to break, and then click Operations > Break .
  3. Select the confirmation check box, and then click Break.


The mirror and vault relationship is broken. The destination volume type changes from data protection (DP) read-only to read/write. The system stores the base Snapshot copy for the relationship for later use.
