Serving data from a SnapMirror DR destination volume

When disaster disables the primary site for a SnapMirror DR relationship, you can serve data from the destination volume with minimal disruption. You can reactivate the source volume when service is restored at the primary site.

  1. Making the destination volume writeable
    You need to make the destination volume writeable before you can serve data from the volume to clients. You can use the snapmirror quiesce command to stop scheduled transfers to the destination, the snapmirror abort command to stop ongoing transfers, and the snapmirror break command to make the destination writeable.
  2. Configuring the destination volume for data access
    After making the destination volume writeable, you must configure the volume for data access. NAS clients, NVMe subsystem, and SAN hosts can access the data from the destination volume until the source volume is reactivated.
  3. Reactivating the original source volume
    You can reestablish the original data protection relationship between the source and destination volumes when you no longer need to serve data from the destination.
