create logical_drive_name available_array available | size

Create a new logical drive with a user name of
logical
. The IQN name that the
initiator uses to access this logical drive is automatically generated. The
character set used for a logical drive must be the character set which is valid for
an IQN.
The logical drive takes its space from the named
array
. Size is entered in bytes,
as a percentage of the total size of the pool. If the
size
is not specified, all of the
available space in that pool is used.
The Access Control must be explicitly defined using the
restricted
or
unrestricted
option. If you enter restricted, you must also enter a list of initiators
which will be used to define the initial ACL.
