Before copying a snapshot, be sure that a suitable target volume exists on the storage array, or create a new target volume specifically for the snapshot.
Caution -
Like any volume copy, a volume copy of a snapshot overwrites all data on the target volume and automatically makes the target volume read-only to data hosts. Ensure that you no longer need the data or have backed up the data on the target volume before starting a volume copy.
To copy a snapshot:
The Array Summary page is displayed.
The Volume Summary page is displayed.
The Snapshot Summary page is displayed.
The Snapshot Details page is displayed.
The Copy Snapshot page is displayed.
Valid values are Highest, High, Medium, Low, and Lowest. The higher the priority, the more resources will be allocated at the expense of the storage array's performance.
Only valid target volumes with capacities equal to or greater than the capacity of the source snapshot are displayed.
Note: Selecting a target volume with a capacity similar to that of the source snapshot reduces the risk of there being unusable space on the target volume after the volume copy has been created.
