Activating the destination volume

When the source volume is unable to serve data due to events such as data corruption, accidental deletion or an offline state, you must activate the destination volume to provide data access until you recover the data on the source volume. Activation involves stopping future SnapMirror data transfers and breaking the SnapMirror relationship.

  1. Verify the status of the source volume.
  2. Break the SnapMirror relationship.
  3. Verify the destination volume status.
  1. Verifying the status of the source volume
    When the source volume is unavailable, you must verify that the source volume is offline and then identify the destination volume that must be activated for providing data access.
  2. Breaking the SnapMirror relationship
    You must quiesce and break the SnapMirror relationship to activate the destination volume. After quiescing, future SnapMirror data transfers are disabled.
  3. Verifying the destination volume status
    After breaking the SnapMirror relationship, you must verify that the destination volume has read/write access and that the destination volume settings match the settings of the source volume.
