Scripting snapshots
Application-based scripting allows automatic snapshots of a volume. For detailed information, see
“Working with scripting” (page 198) and the HP StoreVirtual LeftHand OS Command Line Interface
User Guide, for information about the LeftHand OS software command-line interface.
Mounting a snapshot
A snapshot is a copy of a volume. To access data in the snapshot, you have two choices:
• Create a SmartClone volume from the snapshot to use for data mining, development and
testing, or creating multiple copies. See “Create a new SmartClone volume from the snapshot”
(page 175).
• Mount the snapshot for backing up or data recovery. You assign the snapshot to a server as
a read/write volume and connect to it with an iSCSI initiator.
Mounting a snapshot on a server adds temporary space to the snapshot. See “Managing
snapshot temporary space” (page 173) for more detailed information about temporary space.
Mounting the snapshot on a host
You can add a server to the snapshot when it is created, or add the server later.
1. If it is not already added, add the server on which you want to mount the snapshot to the
management group.
2. Assign the snapshot to the server, and configure the snapshot for read/write access.
3. Configure server access to the snapshot
4. If you mount a Windows application-managed snapshot as a volume, use diskpart.exe
to change the resulting volume's attributes, as described in “Making a Windows
application-managed snapshot available” (page 171).
When you have mounted the snapshot on a host, you can do the following:
• Recover individual files or folders and restore to an alternate location
• Use the data for creating backups
