4.0.0 HP Polyserve Matrix Server Administration Guide (T5392-96052, March 2010)

10 Manage hardware snapshots
Matrix Server provides support for taking hardware snapshots of PSFS filesystems.
The snapshots provide a point-in-time image of a PSFS filesystem. Users or the
Administrator can then use the Microsoft Shadow Copies of Shared Folders feature
to recover individual files or whole volumes from the appropriate snapshot image.
The subdevices containing the PSFS filesystems must reside on one or more storage
arrays that are supported for snapshots.
Supported snapshot methods
Snapshot methods can be configured either on the PolyServe Management Console
“Configure Matrix” window or via the mx config snapshot utility. (See the HP
PolyServe Matrix Server installation guide for more information.) This procedure
creates a snapshot configuration file on each server.
Supported arrays
Hardware snapshots are supported on HP EVA, HP MSA2000, and Engenio storage
arrays.
HP EVA storage arrays
To take hardware snapshots on HP StorageWorks Enterprise Virtual Array (EVA)
storage arrays, the latest version of the HP StorageWorks Scripting System Utility
(SSSU) must be installed on all servers in the cluster. Also, the latest version of
CommandView EVA software must be installed on your Management Appliance. Be
sure that your versions of SSSU and CommandView EVA are consistent. The SSSU
utility must be renamed to:
%Program Files%\Hewlett-Packard\SANworks\Element Manager for
StorageWorks HSV\Bridge\sssu.exe
