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.
Re-creating A Snapshot Virtual Disk Or Consistency Group Snapshot Virtual
Disk
Use the Re-Create option when you want to re-create a snapshot virtual disk or consistency group
snapshot virtual disk that you previously disabled. Re-creating a snapshot virtual disk or consistency
group snapshot virtual disk takes less time than creating a new one.
If you have a snapshot virtual disk or consistency group snapshot virtual disk that you no longer need,
you can reuse it (and any associated snapshot repository virtual disk), instead of deleting it, to create a
different snapshot virtual disk or consistency group snapshot virtual disk of the same base virtual disk. You
can re-associate the snapshot virtual disk or consistency group snapshot virtual disk with the same
snapshot image or a different snapshot image as long as the snapshot image is in the same base virtual
disk.
NOTE: If the snapshot virtual disk or consistency group snapshot virtual disk is part of an online
copy relationship, you cannot perform the Re-create option on the virtual disk.
Keep these important guidelines in mind when you re-create a snapshot virtual disk or consistency group
virtual disk:
• The snapshot virtual disk or consistency group snapshot virtual disk must be in either an Optimal
status or Disabled status.
• For consistency group snapshot virtual disk, all member snapshot virtual disks must be in a Disabled
state before you can re-create the consistency group snapshot virtual disk.
• You cannot re-create an individual member snapshot virtual disk, you can re-create only the overall
consistency group snapshot virtual disk.
• All write data on any associated snapshot repository virtual disk is deleted. Snapshot virtual disk or
consistency group snapshot virtual disk parameters remain the same as the previously disabled virtual
disk parameters. The original names for the snapshot virtual disk or consistency group snapshot virtual
disk are retained. You can change these names after the re-create option completes.
To re-create a snapshot virtual disk or consistency group snapshot virtual disk:
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 → Re-create. The Confirm Re-Create Snapshot Virtual
Disk window is displayed.
– Copy Services → Consistency Group Snapshot Virtual Disk → Re-create. The Confirm Re-
Create Consistency Group Snapshot Virtual Disk window is displayed.
3. Select whether to re-create the snapshot virtual disk or consistency group snapshot virtual disk using
an existing snapshot image, or a new snapshot image and then click Re-create.
The status of the snapshot virtual disk or consistency group snapshot virtual disk is changed from
Disabled to Optimal.
