Description

Default

-c capacity

Specifies the capacity of the LUN. Capacity
can be specified in megabytes (M) or
gigabytes (G) by appending the appropriate
letter to the capacity value.

By default, the LUN will use the entire
capacity available from all the disks. It is
possible to specify a lower value for LUN
capacity, but this will result in unused disk
capacity. Any capacity not included in the
LUN will be inaccessible and is essentially
wasted capacity.

If not specified, the LUN capacity
will equal the total available
capacity of the specified disks.

If a capacity value is specified but
no letter is appended, gigabytes will
be assumed.
