A unique device address (SCSI ID: #n in Figure 7.1) is assigned to each SCSI
device. Input-output devices connected to or under an SCSI device operating as a
target are accessed in logical units. A unique device address (LUN: logical unit
number) is assigned to each logical unit.
An initiator specifies an SCSI ID to select an SCSI device operating as a target,
then specifies an LUN to select the input-output device connected to or under the
target.
An optical disk drive is constructed with all volumes as a single logical unit.
Specificable SCSI IDs and LUN are as follows:
SCSI ID: #0 to #7 selectable (setting terminal or external input)
LUN: #0 (fixed)
