To take hardware snapshots on HP StorageWorks 2000 Modular Smart Array
(MSA2000) storage arrays, the latest version of firmware must be installed on the
array controllers and the SSH Command Line Interface (CLI) service must be enabled
on the array controllers. Also, note that a MSA2000 snapshot license is required.
Only the filesystems located on Master Volumes (not Standard Volumes) are snapshot
capable. To locate MSA2000 array controller firmware, or snapshot license
information, contact your HP representative.
Engenio storage arrays
To take hardware snapshots on Engenio storage arrays, the latest version of SANtricity
Storage Manager client software must be installed on all servers in the cluster. Also,
the latest 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.
