166 Configuration: Premium Feature—Snapshot Virtual Disks
Re-Creating Snapshot Virtual Disks
You can re-create a snapshot virtual disk that you have previously disabled.
CAUTION: Possible loss of data redundancy
—
If the snapshot virtual disk is in
Optimal status, it is first disabled prior to being re-created. This action invalidates
the current snapshot.
Keep these important guidelines in mind when you re-create a snapshot
virtual disk:
• To re-create the snapshot virtual disks correctly, follow the instructions for
your operating system.
NOTE: Failing to follow these additional instructions could create unusable
snapshot virtual disks. For more information, see the
PowerVault Modular
Disk Storage Manager online help
topics.
• To use this option, the snapshot virtual disk must be either in an Optimal
status or Disabled status.
• When using this option, the previously configured snapshot name
parameters and snapshot repository virtual disk are used.
To recreate the snapshot virtual disk:
1
In the AMW, select the
Logical
tab, select a snapshot virtual disk.

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.
