Peripheral Qualifier and Peripheral Device Type: These fields identify the device that is currently connected to
the logical unit. The drive is a single target, single logical unit device. The logical unit number is set to ZERO.
Therefore, the drive normally returns Peripheral Qualifier set to 000b the specified peripheral device type is
currently connected to this logical unit and Peripheral Device Type set to 01h sequential-access device .However,
if the initiator requests a logical unit number greater than ZERO, the drive returns Peripheral Qualifier set to 011b
the target is not capable of supporting a physical device on this logical unit and Peripheral Device Type set to 1Fh
unknown device type.
RMB: The Removable Medium bit of one indicates that the tape can be removed.
Device-Type Modifier: This is a seven-bit user defined code, set to 00h.
ISO Version: This field is ZERO, indicating that the drive does not necessarily comply with the ISO version of
SCSI.
ECMA VERSION: This field is ZERO, indicating that the drive does not necessarily comply with the ECMA version
of SCSI.
ANSI Approved Version: This field indicates the implemented version of the ANSI version.
AENC: The drive does not support asynchronous event notification, so this field is ZERO.
TrmIOP: The drive does not support the Terminate I/O Process message, so this field is ZERO.
Response Data Format: This field is 2, indicating that the INQUIRY DATA format complies with the ANSI version
of SCSI-2.
Additional length: The additional length field specifies the length in bytes of the parameters, in this case, 31
bytes.
RelAdr: The drive does not support the Relative Addressing mode, so this bit is never set.
Wbus16: The drive supports 16-bit wide data transfers, so this bit is set.
