48 Detailed End-to-End iSCSI Setup

• Export Snapshot—Use this option to make Snapshot available to a remote

system or to take a redundant copy of a Snapshot. Use the

Export

Snapshot

wizard to export the Snapshot to one or more iSCSI Targets. The

Snapshot can then be accessed by Initiators (read-only access). To export

snapshot perform the following steps:

Go to the

Active Snapshots

tab, select the snapshot that you want to

export from the middle-pane, right-click and select

Export Snapshot

The

Welcome to the Export Snapshot Wizard

appears. Click

In the

Snapshot Access

screen, add the Targets that you want to grant

read-only access to this Snapshot. Click

Click

Finish

Go to the Target and verify that this snapshot has been added as a

Virtual Disk.

NOTE: In a PowerVault NX1950 cluster solution, the snapshot must be

exported to the targets belonging to the same resource group.

• Delete snapshot—Select the Snapshot that you want to delete, right-click

and click

Delete

NOTE: You cannot delete the Snapshots that are mounted. You must dismount

the Snapshot before deleting it.

• Disk Access – You can mount the Snapshot of an iSCSI Virtual Disk in

read-only mode from the PowerVault NX1950 storage system and it

appears as a local disk.

NOTICE: While dismounting a Snapshot/Virtual Disk, ensure that the disk is not in

use. Failure to do so may cause data corruption.

NOTE: You can either mount iSCSI Virtual Disk (read/write or read/only) or its

Snapshot (read-only), but not both. If you have mounted Virtual Disk and

perform a subsequent mount operation of Snapshot, the previous instance is

dismounted before proceeding.
