Table C-4 SCSI Command Format
Command
Logical Unit The library has a single Logical Unit Number (LUN). The library always appears
Number as LUN 0. If the LUN is specified in the IDENTIFY message, the LUN field in the
CDB is ignored by the library.
Reserved The word Reserved or Rsvd refers to a field defined by the SCSI standard as 0.
The library checks the field for 0. If the field is not 0, the library returns Check
Condition status with a sense key of Illegal Request.
