Initialize a Device
The media init command initializes a device, such as an array.
WARNING! Using the force option of the media init command (media init <device_name>
<block_name> force) destroys the existing data on an array. You should not use this command on a
previously initialized array without first backing up the data on the array.
media init device <device> type [block] [name <name>] [force]
Command Syntax
Enable and Disable Block Storage
[no] media [block] id <id> enable
Enable or disable a specified storage device. The <id> can be found in the output of the show
media all
or show media block id all command.
Caution: When a media device is disabled, all applications using that device immediately stop using
it, and space from other media devices is allocated for them. This may be a disruptive operation.
Show Media Commands
This section provides the syntax for show media commands, along with an explanation of the
functionality of each command.
Show All Media Devices
show media
Display all media devices that can be used by the current HP VMA SAN Gateway (node or module)
as block storage or caching media. This command shows a summary line for each device location,
giving the size and status of that device. Media used by the system for other purposes are not shown.
device <device>
The <device> parameter indicates the array to be initialized, and is a
string of the form:
ata-
VIOLIN_MEMORY_ARRAY_xxxxxxxxxxxxxx
type
The type indicates block (vSHARE) storage.
name
The name parameter is used to name the container. The default is to
reuse the existing name/serial number.
force
The force parameter is used to force initialization of an array that
has already been initialized.
