Table 8.2.1.1 : Standard INQUIRY data format
The Peripheral Qualifier and Peripheral device-type fields indicate the
connected logical unit devices. The autoloader only supports logical unit 0.
Therefore, when LUN is zero, 08h is returned; when LUN is not zero, 7fh is
returned.
Qualifier Description
000b The specified peripheral device type is currently connected to this
logical unit. If the autoloader cannot determine whether or not a
physical device is currently connected, it shall also use this
peripheral qualifier when returning the INQUIRY data.
This peripheral qualifier does not mean that the device is ready for
access by the initiator.
001b The autoloader is capable of supporting the specified peripheral
device type on this logical unit; however, the physical device is not
currently connected to this logical unit.
010b Reserved
011b The autoloader is not capable of supporting a physical device on
this logical unit. For this peripheral qualifier the peripheral device
type shall be set to 1Fh to provide compatibility with previous
versions of SCSI. All other peripheral device type values are
reserved for this peripheral qualifier.

Table 8.2.1.3 : Peripheral device type
A Removable medium (RMB) bit of 1 indicates that the media is removable.
When it is 0, the media is not removable. Because the autoloader handles
removable media, this field is 1.
00h is returned for the Device-type modifier field.
