Chapter 3: mx Commands 110

--method <type>

The method can be hpeva or engenio. This option must always be specified

for engenio snapshots. For hpeva snapshots, the option is needed only if more

than one snapshot method is configured on the system.

--terse

On success, only the name of the snapshot volume is printed.

Any of the options returned by the mx snapshot showcreateopt command, as

described below.

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:

1 2 ... 116 117 118 119 120 121 122 123 124 125 126 ... 140 141
