Disabling A Snapshot Virtual Disk - Dell PowerVault MD3220 Owner's Manual

Disabling a Snapshot Virtual Disk

Disable a snapshot virtual disk if one of the following conditions exists:
• You do not need the snapshot now.
• You intend to re-create the snapshot at a later time and want to retain the
associated snapshot repository virtual disk so that you do not need to
create it again.
• You want to maximize storage array performance by stopping copy-on-
write activity to the snapshot repository virtual disk.
NOTE:
If you do not intend to re-create the snapshot virtual disk at a later time, in
the Logical pane, select the snapshot virtual disk, and select Virtual Disk
to remove it. The associated snapshot repository virtual disk is also removed. Refer
to the PowerVault Modular Disk Storage Manager online help topics for more
information on removing a snapshot virtual disk.
NOTE:
The SMdevices utility displays the snapshot virtual disk in its output, even
after the snapshot virtual disk is disabled.
To disable a snapshot virtual disk:
1 In the AMW, select the Logical tab, select the snapshot virtual disk, and
select Virtual Disk Snapshot Disable.
2 In the text box, type yes and click OK.
The snapshot virtual disk is disabled. The associated snapshot repository
virtual disk does not change status. The copy-on-write activity to the
snapshot repository virtual disk stops until the snapshot virtual disk is re-
created.
