Disabling a Snapshot Virtual Disk
If you no longer need a , you might want to disable it because, as long as a snapshot virtual disk is enabled, your performance is impacted by the activity to the associated . When you disable a snapshot virtual disk, the copy-on-write activity stops.
If you disable the snapshot virtual disk instead of deleting it, you can retain it and its associated repository. Then, when you need to create a different snapshot of the same , you can use the re-create option to reuse a disabled snapshot. This takes less time than creating a new one.
When you disable a snapshot virtual disk:
You cannot use that snapshot virtual disk again until you use the re-create option on that .
Only that snapshot virtual disk is disabled. All other snapshot virtual disks remain functional.
If you do not intend to re-create a snapshot, you can delete that snapshot virtual disk instead of disabling it.
Re-creating a Snapshot Virtual Disk
Re-creating a snapshot virtual disk takes less time than creating a new one.
If you have a snapshot virtual disk that you no longer need, instead of deleting it, you can reuse it (and its associated snapshot repository virtual disk) to create a different snapshot virtual disk of the same source virtual disk.
When you re-create a snapshot virtual disk:
The snapshot virtual disk must be in either an optimal or a disabled state.
All copy-on-write data on the snapshot repository virtual disk is deleted.
Snapshot and snapshot repository virtual disk parameters remain the same as the previously disabled snapshot virtual disk and its associated snapshot repository virtual disk. After the snapshot virtual disk is re-created, you can change parameters on the snapshot repository virtual disk through the appropriate menu options.
The original names for the snapshot and snapshot repository virtual disks will be retained. You can change these names after the re-create option completes.
