4.1.0 HP PolyServe Matrix Server administration guide (T5392-96073, October 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.
IMPORTANT:
Snapshots should be deleted only from the PolyServe Management Console or with
the mx snapshot destroy command. Deleting snapshots directly on the array,
without using the PolyServe Management Console or the mx command, might leave
the cluster unstable.
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 Patha or Unassign Paths as appropriate. If you are assigning a
drive letter or path to a snapshot, the Assign a Matrix-Wide Drive Letter or Path
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.
