Creating a custom snapshot collection
You can create snapshots of multiple volumes in a single operation, without using a volume collection. The set of
snapshots, one for each volume, is called a custom snapshot collection.
Requirement: Before
you create a custom snapshot collection, you must allocate snapshot reserve for each
volume in the volume collection. See About snapshot reserve settings on page 1
1-2.
1. Click
Volumes and then Custom snapshot collections.
2. In the Create Custom Snapshot Collection – General Settings dialog box, enter a name for the custom snapshot
c
ollection (up to 63 ASCII characters) and an optional description (up to 127 ASCII characters). You cannot
specify spaces in the name. Then, click
Next.
3. In the Create Custom Snapshot Collection – Components dialog box, s
elect the volumes and click Next.
4. In the Create Custom Snapshot Collection – Summary di
alog box, review the information. If correct, click
Finish. Click Back to make changes.
The default custom snapshot collection name is the volume
collection name followed by the date and time when
you created the snapshots (for example,
UserData-2009-05-14-15:08:18.3).
To display custom snapshot collections, see Displaying custom snapshot collections on pag
e 11-7.
Displaying custom snapshot collections
To see information about a custom snapshot collection, you must know the timestamp for the custom snapshot
collection, which is the same as the timestamp for its snapshots.
Note: A custom snapshot collection is not associate

Click
Volumes and then expand Custom Snapshot Collections. The Custom Snapshot Collections panel
provides the following information:
• The name, timestamp, and status of the custom snapshot.
• Accessibility (security) of, and connections to the custom
snapshot

ne help for information about the data fields and options.
