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.
About this task
- Run the volume show <volumename> -instance and volume snapshot policy show commands to verify the source and destination volume settings, including the volume type "rw – read/write access", Snapshot policies, thin provisioning, deduplication, compression, and autogrow settings. You can use the volume setting information that you noted after creating the SnapMirror relationship to verify the destination volume settings.
For more information about how to use the commands, see the man pages.
