Copying a Volume Snapshot

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:

  1. Click Sun StorEdge 6130 Configuration Service.
  2. The Array Summary page is displayed.

  3. Click the array for which you want to copy a snapshot.
  4. The Volume Summary page is displayed.

  5. Click Logical Storage > Snapshots.
  6. The Snapshot Summary page is displayed.

  7. Click the name of the snapshot that you want to copy.
  8. The Snapshot Details page is displayed.

  9. Click Copy.
  10. The Copy Snapshot page is displayed.

  11. Select a copy priority.
  12. 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.

  13. Select a target volume from the Target Volumes list.
  14. 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.

  15. Stop all I/O activity to the snapshot and target volume.
  16. Unmount any file systems on the source volume and target volume, if applicable.
  17. Review the specified information. If you are satisfied, click OK. Otherwise, click Cancel.
  18. Remount any file systems on the source volume and target volume, if applicable.
  19. Enable I/O activity to the snapshot volume and target volume.
