Note: In compliance with the SCSI specification, the unit will terminate the command with a CHECK
CONDITION status and the sense key will be set to ILLEGAL REQUEST when a reserved bit, byte, field or
code is not ZERO.
The unit has an embedded SCSI controller interface and therefore is a single target, single logical unit device on
the SCSI bus. The Obsolete for the drive is fixed and is set to ZERO. In order to be SCSI-2 or SCSI-3 compatible,
the following scheme is used to check the LUN:
SCSI-2 states that the LUN addressed by the initiator will appear in the IDENTIFY message sent to the target on
selection. LUN field inside of CDB will be “obsolete”.
