4.1.0 HP PolyServe Software command reference guide (T5392-96071, October 2010)

volume that you want to snapshot, run the following command. In the command,
<volume> is the psd or psv device containing the filesystem that you want to
snapshot.
mx snapshot showcreateopt <volume>
destroy—Destroy a snapshot
mx snapshot destroy <volume>
showcreateopt—Show snapshot options for the storage array associated with a
volume
mx snapshot showcreateopt <volume>
The output specifies the options that are available for the snapshot methods configured
on your system. The following options are available for all snapshot methods:
--label “<label>”
An identifier for the snapshot. The label must be enclosed in double quotation
marks and can include up to 63 characters. The default is “Snapshot of volume”.
--scsf false|true
Whether the snapshot should be shared as a shadow copy of a shared folder.
The default is true.
The following option applies to hpeva snapshots:
--allocation_policy fully|demand|copy
The type of snapshot. The allocation policy for all snapshots of a particular virtual
disk is determined by the oldest snapshot of that virtual disk. The choices here
are only a preference. fully reserves the maximum amount of disk group resources
needed at snapshot creation time and is the default. demand reserves the minimum
amount of disk group resources needed. copy creates a complete copy of the
original volume (a snapclone).
The following option applies to engenio snapshots:
--repositoryPercentOfBase
The snapshot process creates a repository on disk that stores pointers to the data
in the source filesystem. As changes are made to the filesystem, subsequent
snapshots will copy the changed data to the repository. This option asks for the
initial size of the repository. The size is specified as a percentage of the volume
holding the filesystem. The default is 20% of the base volume.
