8.4.4.4 Media Loader Inquiry Response
The DLT4000 controller generates INQUIRY Data on the Medium Changer LUN that
is very similar to that of the tape drive LUN. The key differences are:
• Peripheral Device Type is set to "8" for SCSI-2 Medium Changer
• Product ID bytes are set to DLT4700 for a 7 cartridge loader.
