3. Internal connection
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. The logical view of the tape library is shown in
“Logical view of traditional
configuration” (page 8) .
