Chapter 11: Manage Hardware Snapshots 135
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.
Engenio Storage Arrays
To take hardware snapshots on Engenio storage arrays, a supported
version of SANtricity Storage Manager client software must be installed
on all servers in the cluster. Also, a supported version of firmware must
be installed on your storage array controllers. To locate this software and
firmware, contact your Engenio representative.
Create a Snapshot or Snapclone
A snapshot is a space-efficient reflection of a source filesystem at a
particular point in time and is intended to be temporary. Snapshots can be
both readable and writable. A matrix can include multiple snapshots of
the same filesystem taken at different times.
A snapclone is similar to a snapshot, except that it completely copies the
source filesystem data at a particular point in time. Snapclones are
supported only on HP arrays.
To create a snapshot or snapclone, select the filesystem on the
Management Console, right-click, and select Create Snapshot (or select
Edit > Filesystem > Create Snapshot). You will then see a dialog asking for
information specific to your snapshot method.
