Standard Inquiry Data Page — Field Descriptions
Field Name
Description
Peripheral Qualifier
The tape drive returns one of the following values in this field:
000b
The indicated Peripheral Device Type is connected to the logical
unit.
001b
The indicated Peripheral Device Type is not connected to the
logical unit; however, the tape drive is capable of supporting the
indicated Peripheral Device Type at the specified logical unit.
011b
The target is not capable of supporting a physical device on this
logical unit. In this case, the Peripheral Device Type is 1Fh.
Peripheral Device Type
On the tape drive LUN, this field is 01h, indicating a sequential access device. On
the Medium Changer LUN, this field is 08h. All other LUNs return 1Fh.
Other Inquiry Data
Fields
The rest of the fields in the Inquiry Response are used as follows:
Byte 1
RMB – Removable Medium bit. Set to 1.
Device Type Modifier. Set to 0.
Byte 2
ISO Version. Set to 0
ECMA Version. Set to 0
ANSI Approved Version. Set to 02h, indicating compliance with
SCSI-2
Byte 3
ANEC. Set to 0 (Asynchronous Event Notification not
supported)
TrmIOP. Set to 0 (TERMINATE I/O PROCESS message not
supported)
Response Data Format. Set to 2 (Inquiry Data in SCSI-2 format)
Byte 4
Additional Length. The tape drive sets this field to indicate the
number of additional bytes of INQUIRY Response Data
available.
Byte 6
All bits set to 0, except MChngr – Set to 1 if an integrated Media
Loader is present and EEPROM parameter EnbIngMedChgr
is 1. This SCSI-3 bit indicates that the initiator can issue READ
ELEMENT STATUS and MOVE MEDIUM commands to the
tape drive LUN (0). By default, this bit is 0.
