In the typical bridged library controller connection each tape drive has one physical link to the SAN switch
and connects to the SAN switch as one Fibre Channel device.
The tape drive hosting the library controller path connects as one Fibre Channel device containing two
logical units. The tape drive is logical unit number zero and the tape library is logical unit number one.
The tape library Fibre Channel device contains a tape drive logical unit and a media changer logical unit.
