Modify Snapshot Properties
After a snapshot is created, you can modify the settings of the snapshot.
1. Click the Storage view.
2. In the Storage pane, select a PS Series group.
3. Click the Storage tab.
4. In the Storage tab navigation pane, expand the Volumes node and select a volume that contains a snapshot.
5. From the Snapshots tab, select a snapshot to modify.
6. Click Edit Settings. The Modify Snapshot Properties dialog box opens.
7. In the Name eld, type a name for the snapshot.
8. (Optional) In the Description eld, type a description for the snapshot.
9. In the Snapshot iSCSI Settings area, type a value in the Public Alias eld to specify a public alias for the snapshot.
10. In the Shared Access area, select the Allow simultaneous connections from initiators with dierent IQNs checkbox if your
environment supports multiple initiators accessing a volume.
11. In the Read-Write Permissions area, set the read-write permissions for the snapshot.

Control Snapshot Space Borrowing
You can control whether or not a volume is allowed to borrow space for snapshots. Snapshot space borrowing enables you to
temporarily increase the available snapshot space for a volume by borrowing space from other sources. Borrowing can help prevent
the oldest snapshots from potentially being deleted when the allocated snapshot reserve of a volume is depleted.
1. Click the Storage view.
2. In the Storage pane, select a PS Series group.
3. Click the Storage tab.
4. In the Storage tab navigation pane, select a volume.
5. In the right pane, click Edit Snapshot Policy. The Edit Snapshot Policy dialog box opens.
6. Select the action to perform when creating a snapshot exceeds the snapshot reserve.
• Set volume oine — This option sets the volume and snapshots oine.
• Delete oldest snapshot — This option deletes the oldest snapshots to free up space for new snapshots.
7. If the Delete oldest snapshot option is selected, you can select the Borrow snapshot space as needed checkbox to enable the
PS Series group to borrow space for snapshots.
8. Click OK.
Set a Snapshot Online or Oine
When you create a snapshot, the PS Series group sets the snapshot oine by default. An iSCSI initiator on a computer cannot
discover or connect to an oine snapshot. To make a snapshot accessible to iSCSI initiators, set the snapshot online.
1. Click the Storage view.
2. In the Storage pane, select a PS Series group.
3. Click the Storage tab.
4. In the Storage tab navigation pane, select a volume that contains a snapshot.
5. From the Snapshots tab, select a snapshot.
6. If the snapshot is oine, click Set Online to set the snapshot online.
If the snapshot is online, click Set Oine to set the snapshot oine.
7. Click OK.
