3.4.0 Matrix Server Administration Guide

Manage Hardware Snapshots

Matrix Server provides support for taking hardware snapshots of PSFS

filesystems. The subdevices on which the filesystems are located must

reside on one or more storage arrays that are supported for snapshots.

Snapshot support can be configured on the Management Console

“Configure Matrix” window. (See the PolyServe Matrix Server Installation

Guide for more information.) This procedure creates a snapshot

configuration file on each server.

NOTE: Currently hardware snapshots are supported only on Hewlett-

Packard 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 for HP EVA snapshots to work. To obtain this utility, go to

www.hp.com, select Software & Driver Downloads, and search for

“HP StorageWorks Command View EVA Software.” Choose the

latest media kit version, and select the correct version for your OS.

The current media kit version is v4.1. The utility must be renamed

to %Program Files%\Hewlett-Packard\SANworks\Element

Manager for StorageWorks HSV\Bridge\sssu.exe. You will also

need to install Microsoft Knowledge Base Hotfix 899415. The

hotfix is available at the following Web site:
