4.0.0 HP Polyserve Matrix Server Administration Guide (T5392-96052, March 2010)

To delete a snapshot from the command line, enter 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.
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, enter the
following:
mx fs assignpath --path <path or driveletter> <snapshot>
<ALL_SERVERS | server ...>
To unassign a drive letter or path, enter the following:
mx fs unassignpath <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 HP
PolyServe Software for Windows File Serving administration guide. CIFS clients then
use Windows Explorer to access the shadow copies.
To enable a CIFS client to use shadow copies, you will need to install the Shadow
Copies of Shared Folders client pack on the CIFS client workstation. The client pack
is provided in the Windows 2003 distribution and can be installed from the following
location, where C is the drive where Windows 2003 is installed:
C:\windows\system32\clients\twclient\x86\twcli32.msi
