User`s guide

Adaptec Storage Manager has a snapshot wizard to help you create a snapshot and
snapshot sets (a group of snapshots taken at the same time). A snapshot can include
one volume or multiple volumes. You cannot create a snapshot of either a mirrored
volume (the mirror manager) nor its mirror (the mirror plex). You can’t work with
any individual snapshot in a snapshot set; only the complete snapshot set can be
mounted or deleted, for example.
You can choose to run a snapshot job immediately, or schedule it for another time.
Before You Begin
Ensure that the VSS Provider (see page 17) is installed on the system on which you
plan to take snapshots. Also ensure that Microsoft Hotfix 913648 or equivalent is
installed on the system. Refer to http://support.microsoft.com/kb/895092
.
Creating a Snapshot from an iSCSI Storage Host Volume
You can create a up to 256 separate snapshots on one iSCSI Storage Appliance. (You
can include multiple volumes in one snapshot). When you are creating snapshots
for a mirrored volume, snapshots will be created on the mirror master plex only.
To create a snapshot:
1 In the Enterprise View, select the iSCSI Storage Host you want.
2 In the Volumes View, select any volume.
3 Click the Snapshots button (shown at right). Or, In the Actions menu, select
Create snapshot.
The wizard opens.
4 Select the volume(s) you want to include in the snapshot set.
Note If the volume you select has dependent volumes listed, Adaptec strongly
recommends that you copy the volume and its dependencies, to avoid losing
related data.
5 Type a name or description for the snapshot, then click Next.
The Snapshot Settings screen opens. The pool for the snapshot is automatically
assigned.
6 Set the mount point for the snapshot. (If you don’t want to mount the snapshot,
select
None from the iSCSI Storage Host drop-down list, then skip to Step 7.)
a Select the iSCSI Storage Host where you want to mount the snapshot, then
assign a drive letter.
All volumes in a snapshot set are mounted or unmounted. If you mount the
snapshot set, all volumes are mounted on the same server.
