Configuration: Premium Feature—Snapshot Virtual Disks 163
Snapshot Repository Capacity
If you receive a warning that the capacity for the snapshot repository virtual
disk is approaching its threshold, you can increase the capacity of a snapshot
repository virtual disk by using one of the following methods:
• Use the free capacity available on the disk group of the snapshot repository
virtual disk.
• Add unconfigured capacity to the disk group of the snapshot repository
virtual disk. Use this option when no free capacity exists on the disk group.
You cannot increase the storage capacity of a snapshot repository virtual disk
if the snapshot repository virtual disk has any one of the following conditions:
• The virtual disk has one or more hot spare drives in use.
• The virtual disk has a status other than Optimal.
• Any virtual disk in the disk group is in any state of modification.
• The controller that has ownership of this virtual disk is currently adding
capacity to another virtual disk. Each controller can add capacity to only
one virtual disk at a time.
• No free capacity exists in the disk group.
• No unconfigured capacity is available to add to the disk group.
NOTE: You can add a maximum of two physical disks at one time to increase
snapshot repository virtual disk capacity.
To expand the snapshot repository virtual disk from MDSM:
1
In the AMW, select the
Logical
tab.
2
Select the snapshot repository virtual disk for which you want to increase
the capacity.
3
Select

Increase Capacity
.
NOTE: If no free capacity or unconfigured capacity is available, the Increase
Capacity option is disabled.

window displays the Virtual
disk attributes. The snapshot repository virtual disk name, the associated
snapshot virtual disk name, the associated source virtual disk capacity and
name, the current capacity, and the amount of free capacity that is
available for the selected snapshot repository virtual disk appear. If free
