Chapter 10: Manage Hardware Snapshots 191

To create a snapshot from the command line, first run the following

command to determine the options available for the array type on which

the specified volume is located:

mx snapshot showcreateopt <volume>

Then run the following command to create the snapshot:

mx snapshot create [--terse] [<options>] <volume>

The --terse option causes only the name of the snapshot volume to be

printed on success.

Errors During Snapshot Operations

If the snapshot operation could not be completed, errors will be reported

to the matrix log. You will need to review these errors and may need to

delete any partial snapshots by using the Management Appliance.

Delete a Snapshot

Storage arrays typically limit the number of snapshots that can be taken

of a specific filesystem. Before taking an additional snapshot, you will

need to delete an existing snapshot. Also, if you want to destroy a

filesystem, you will first need to delete all snapshots of that filesystem.

To delete a snapshot, select the snapshot on the Management Console,

right-click, and select Delete.

To delete a snapshot from the command line, type the following:

mx snapshot destroy <volume>

Snapclone devices, like regular filesystem LUNs, cannot be deleted

from the Management Console. To delete snapclones, you must destroy

the filesystem and/or volume, deport the LUN(s), and delete the LUN(s)

using the appropriate array-specific utilities.

Mount or Unmount Snapshots

Snapshots can be mounted or unmounted in the same manner as

filesystems. Select the snapshot on the Management Console, right-click,

and select Mount or Unmount as appropriate. If you are mounting a
