158 Configuration: Premium Feature—Snapshot Virtual Disks
Disabling a Snapshot Virtual Disk
Disable a snapshot virtual disk if:
• 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 DiskDelete
to remove it. The associated snapshot repository virtual disk is also removed. See
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.
