The Peripheral Device Type and Peripheral Qualifier fields identify the physical device
currently connected to the logical unit. The Peripheral Qualifier is described in
Table 4-20 and the Peripheral Device Type is described in Table 4-21. Table 4-22
shows the possible combinations of peripheral qualifiers and device types generated
based on which LUN the INQUIRY command is sent to. In the case where INQUIRY
data byte 0 is 7Fh (i.e. an unknown or no device type is connected to this LUN) the
logical unit product ID (bytes 24-31) will contain ASCII spaces (20h).
The Device-type Modifier field is not supported and is returned as all zeroes.
1 The RMB (Removable Medium) bit is set to one indicating that the medium is remov-
able.
The ANSI-approved version field of 2h indicates this device complies to the ANSI
SCSI-2 standard (X3.131-1994, version 10L).
0 Zero codes in the ISO version and ECMA version fields indicate no compliance is
claimed with the ISO version of SCSI (ISO 9316) or the ECMA version of SCSI
(ECMA-111).
A Response Data Format is set to a value of 2 indicating that this INQUIRY data is
formatted based on the format specified by the ANSI SCSI-2 standard (X3.131-1994,
version 10L).
0 The Terminate I/O Process (TrmIOP) bit is set to zero, indicating the device does not
support the Terminate I/O Process message.
0 The Asynchronous Event Notification Capability (AENC) bit is set to zero, indicating
the device does not support SCSI-2 defined asynchronous event notifications.
The Additional Length field indicates 99 additional bytes of parameters are supplied.
If the allocation length in the INQUIRY CDB is too small to transfer all of these
parameters, the additional length is not adjusted to reflect the truncation by the initia-
tor.
0 The Soft Reset (SFTRE) bit is set to zero indicating the target does not support the
Soft Reset option.
0 The Command Queuing (CmdQ) bit is set to zero indicating the target does not sup-
port command queuing for this logical unit.
1 The Linked command (Link) bit is set to one indicating the target supports linked
commands for this logical unit.
1 The Synchronous Transfer (Sync) bit is set to one indicating the target supports syn-
chronous data transfer.
