3.4.0 Matrix Server Administration Guide

Chapter 9: Manage Hardware Snapshots 108

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)

with the array-specific utilities.

Assign or Remove Drive Letters or Mount

Paths

Drive letters or mount paths can be assigned or unassigned to snapshots

in the same manner as filesystems. Select the snapshot on the

Management Console, right-click, and select Assign Path or Unassign

Paths as appropriate. If you are assigning a drive letter or path to a

snapshot, the Assign a Matrix-Wide Drive Letter window appears,

allowing you to specify the appropriate drive letter or path.

To assign a drive letter or path to a snapshot from the command line, type

the following:

mx fs assignpath --path <path or driveletter> <snapshot>

<ALL_SERVERS | server ...>

To unassign a drive letter or path from the command line, type the

following:

mx fs unassign <snapshot> <ALL_SERVERS | server ...>

Using Shadow Copies of Shared Folders

When you take a snapshot of a PSFS filesystem, you can specify that it

should be shared as a shadow copy. The snapshot provides a point-in-

time version of the filesystem. Users who have accidently lost or changed

a file can access the appropriate shadow copy of the filesystem and

retrieve or copy the previous version of the file.

Shadow copies of PSFS filesystems are intended to be used with CIFS.

The filesystem is shared via Matrix File Shares or Virtual File Shares, as

described in the Matrix File Serving Solution Pack for CIFS Administration
