ONTAP 7-Mode Transition

Deleting 7-Mode volume Snapshot copies from transitioned volumes

Because the 7-Mode volume Snapshot copies are not deleted automatically from a transitioned volume, you must delete these Snapshot copies manually after the transition operation is completed.

Because the naming convention for Snapshot copies differs between 7-Mode environments and clustered Data ONTAP, the 7-Mode Snapshot copies cannot be automatically overwritten by the Snapshot copies in the clustered Data ONTAP environment.

To achieve better space utilization, you should delete the unwanted 7-Mode Snapshot copies, including the ones from the 7-Mode to 7-Mode SnapMirror relationships and the 7-Mode to clustered Data ONTAP SnapMirror relationships.

Steps

  1. After the storage cutover operation is completed, delete the unwanted 7-Mode Snapshot copies:

    snap delete -vserver <svm_name> -volume <volume_name> -snapshot <snapshot_name>
