Manage Hardware Snapshots
Matrix Server provides support for taking hardware array-based
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 PolyServe Matrix Server Installation Guide for

on each server.
Hardware snapshots are supported on Hewlett-Packard StorageWorks
Enterprise Virtual Array (EVA) storage arrays and Engenio storage
arrays. See the Hardware and Software Configuration Guide for the
supported software and firmware versions.
HP EVA Storage Arrays
To take hardware snapshots or snapclones on Hewlett-Packard
StorageWorks Enterprise Virtual Array (EVA) storage arrays, a supported
version of the HP StorageWorks Scripting System Utility (SSSU) must be
installed on all servers in the cluster. Also, a supported version of
