Disabling Snapshot Virtual Disk or consistency group Snapshot Virtual Disk

Use the Disable option when you want to invalidate a snapshot copy or a consistency group snapshot virtual disk. If the snapshot virtual disk or consistency group snapshot virtual disk is designated as read-write, this option also allows you to stop any further write activity to its associated snapshot repository virtual disk.

Use the Disable option if one of these conditions applies:
  • You are finished with the snapshot virtual disk or consistency group snapshot virtual disk for the time being.
  • You intend to re-create the snapshot virtual disk or consistency group snapshot virtual disk (that is designated as read-write) later and want to retain the associated snapshot repository virtual disk so that it does not need to be created again.
  • You want to maximize the storage array performance by stopping write activity to the snapshot repository virtual disk.
If you decide to re-create the snapshot virtual disk or consistency group snapshot virtual disk, you must choose a snapshot image from the same base virtual disk.
If you disable the snapshot virtual disk or consistency group snapshot virtual disk, the system performs the following actions:
  • Retains the World-Wide Name (WWN) for the snapshot virtual disk or consistency group snapshot virtual disk.
  • Retains the snapshot virtual disk or consistency group snapshot virtual disk’s association with the same base virtual disk.
  • Retains the snapshot virtual disk or consistency group snapshot virtual disk’s associated repository—if the virtual disk is designated as read-write.
  • Retains any host mapping and access (any read-write requests fail).
  • Removes the snapshot virtual disk or consistency group snapshot virtual disk’s association with the current snapshot image.
  • For a consistency group snapshot virtual disk, disables each member’s snapshot virtual disk.
NOTE: If you are finished with the snapshot virtual disk or consistency group snapshot virtual disk and do not intend to re-create it later, you must delete the virtual disk, instead of disabling it.
  1. From the AMW, select the Storage & Copy Services tab.
  2. Select the snapshot virtual disk or consistency group snapshot virtual disk that you want to disable and then select one of the following:
    • Copy Services > Snapshot Virtual disk > Disable. The Confirm Disable Snapshot Virtual Disk window is displayed.
    • Copy Services > Consistency Group Snapshot Virtual Disk > Disable. The Confirm Disable Consistency Group Snapshot Virtual Disk window is displayed.
  3. Type yes in the text box and then click Disable to disable the snapshot virtual disk.
    The snapshot virtual disk or consistency group snapshot virtual disk is displayed in the Logical pane with the Disabled Snapshot status icon. If you disabled a read-write snapshot virtual disk or consistency group snapshot virtual disk, its associated snapshot repository virtual disk does not change status. The write activity to the snapshot repository virtual disk stops until the snapshot virtual disk or consistency group snapshot virtual disk is re-created.
