Snapshot Virtual Disks 79
• Whether you use the software-supplied sequence number that (by
default) populates the
Snapshot virtual disk name
or the
Snapshot
repository virtual disk name
field, the next default name for a snapshot or
snapshot repository virtual disk still uses the sequence number determined
by the software. For example, if you give the first snapshot of source virtual
disk
Accounting
the name
Accounting-8
, and do not use the software-
supplied sequence number of 1, the default name for the next snapshot of
Accounting
is still
Accounting-2
.
• The next available sequence number is based on the number of existing
snapshots of a source virtual disk. If you delete a snapshot virtual disk, its
sequence number becomes available again.
• You must choose a unique name for the snapshot virtual disk and the
snapshot repository virtual disks, or an error message is displayed.
• Names are limited to 30 characters. After you reach this limit in either the
Snapshot virtual disk name
or the
Snapshot repository virtual disk name
fields, you can no longer type in the field. If the source virtual disk is
30 characters, the default names for the snapshot and its associated
snapshot repository virtual disk use the source virtual disk name truncated
enough to add the sequence string. For example, for
Host Software
Engineering Group GR-1
, the default snapshot name is
Host Software
Engineering GR-1
, and the default repository name would be
Host
Software Engineering GR-R1
.
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.
