3.1 Control/Sense Commands

a. Qualifier field

(0,0,0): The specified logical unit shows the type of input/output device shown in the "Device Type Code" field. Even if this code is reported, it does not mean that that logical unit is in the ready state.

(0,0,1): The specified logical unit shows the type of input/output device shown in the "Device Type Code" field, but it shows that an actual input/output device is not connected to that logical unit. The IDD does not report this code.

(0,1,1): Shows that the specified logical unit is not supported. When this code is reported, it X '1F' is shown in the "Device Type Code" field.

b.Device type code

(0,0,0,0,0): Direct access device

(1,1,1,1,1): Undefined device

When LUN=0 is specified, the IDD reports "(0,0,0,0,0) : direct access device" as the device type code. At this time, the "Qualifier" field is "(0,0,0)." Therefore, byte 0 indicates X '00.' On the other hand, when a LUN other than "0" is specified, the IDD reports "(1,1,1,1,1) : undefined device" as the device type code. At this time, the "Qualifier" field is "(0,1,1)." Therefore, byte 0 indicates X '7F.'

c.RMB bit

When this bit is "1," it indicates that the storage media is a removable disk device. The IDD is a fixed disk device, so this bit is always reported as "0."

d.Version

The VERSION field indicates the implemented version of this standard and is defined below.

Code

Description

 

 

 

X'01'

ANSI X3.131: 1986

(SCSI-1)

 

 

 

X'02'

ANSI X3.131: 1994

(SCSI-2)

 

 

 

X'03'

ANSI X3.301: 1997

(SPC Rev.11)

 

 

X'04'

T10/1236-D (SPC-2)

 

 

 

e.Response data format field

This field shows the code which shows the standard INQUIRY data format. The definition of the code is (0,0,0,1) for SCSI-1/CCS mode or (0,0,1,0) for SCSI-2 or SCSI-3 mode.

f.Additional data length

This field shows the length of the INQUIRY data (byte length) after byte 5. This value shows the length in the INQUIRY data held by the IDD without relation to the specification in the transfer byte length field in the CDB, and is always X‘5B’ (total data length = 96 bytes).
