Page 108 highlights

Available Subdevices: The display includes all imported subdevices that are not currently in use by another volume and that do not have a filesystem in place. Subdevices belonging to unimported volumes that are on imported disks are also included in the display. The subdevices that you select are used in the order in which they appear on the list. Use the arrow keys to reorder, one-at-a-time, the appropriate subdevices and then highlight those subdevices. Striping: If you want this volume to use striping, check Enable striping and then select the size of the stripe. HP recommends that you increase the stripe size to at least 2 MB. Click either OK or Apply to create the volume. (Apply keeps the window open, allowing you to create additional dynamic volumes.) NOTE: If you selected a subdevice that is associated with an unimported volume, you will see a message reporting that the subdevice contains a volume signature. The message asks whether you want to destroy the affected unimported dynamic volume and reuse this subdevice in the new volume you are creating. Be sure that you do not need the unimported dynamic volume before doing this. If the unimported volume associated with the subdevice is in a "duplicate" state, the attempt to destroy the volume will fail. See Unimportable volumes, page 118 for more information. When the dynamic volume has been created, the Management Console reports the psv name assigned to the volume. On the Management Console, filesystems are identified with the psv name of the dynamic volume on which they are located, as shown below. To create a dynamic volume from the command line, use the following command: mx dynvolume create [--stripesize ] You can use either spaces or commas to separate the subdevice names. The following command lists the available subdevices: mx dynvolume showcreateopt 108 Configure dynamic volumes

Available Subdevices:
The display includes all imported subdevices that are not
currently in use by another volume and that do not have a filesystem in place.
Subdevices belonging to unimported volumes that are on imported disks are also
included in the display. The subdevices that you select are used in the order in which
they appear on the list. Use the arrow keys to reorder, one-at-a-time, the appropriate
subdevices and then highlight those subdevices.
Striping:
If you want this volume to use striping, check
Enable striping
and then select
the size of the stripe. HP recommends that you increase the stripe size to at least 2
MB.
Click either
OK
or
Apply
to create the volume. (Apply keeps the window open,
allowing you to create additional dynamic volumes.)
NOTE:
If you selected a subdevice that is associated with an unimported volume, you will
see a message reporting that the subdevice contains a volume signature. The message
asks whether you want to destroy the affected unimported dynamic volume and reuse
this subdevice in the new volume you are creating.
Be sure that you do not need the unimported dynamic volume before doing this.
If the unimported volume associated with the subdevice is in a
duplicate
state, the
attempt to destroy the volume will fail. See
Unimportable volumes
, page 118 for more
information.
When the dynamic volume has been created, the Management Console reports the
psv
name assigned to the volume. On the Management Console, filesystems are
identified with the
psv
name of the dynamic volume on which they are located, as
shown below.
To create a dynamic volume from the command line, use the following command:
mx dynvolume create [--stripesize
<4KB-64MB>
]
<subDevice ...>
You can use either spaces or commas to separate the subdevice names.
The following command lists the available subdevices:
