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:
a
Go to the Active Snapshots tab, select the snapshot that you want to
export from the middle-pane, right-click and select
Export Snapshot.
b
The Welcome to the Export Snapshot Wizard appears. Click Next.
c
In the Snapshot Access screen, add the Targets that you want to grant
read-only access to this Snapshot. Click
Next.
d
Click Finish.
e
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.
