Thick. All storage space that you specify when you create a thick LUN is allocated
up front and the storage space is reserved on the volume. Snapshots, other LUNs,
and shares on the volume cannot consume storage space that is reserved. The size
of the LUN is reported as the total storage space that you specify when you create
the LUN. You cannot assign more storage space than the available nonreserved
storage space on the volume.
Default LUN Settings
The following table explains the default settings of a LUN. You can change these settings
when you create or change the LUN. The defaults depending on whether the LUN is
thick provisioned (the default), or you select thin provisioned.
