Fujitsu MAN3367, MAN3735, MAN3184 specifications VPD information VPD identifier list

(7)VPD information

When "1" is specified in the "EVPD" bits of the CDB, the VPD information described below is transferred to the INIT by this command. The INIT specifies the type of VPD information required in the "Page code" field of the CDB. The type of VPD information supported by the IDD and its page code number are as shown below.

Page Code Page (Hex)	Function
00	Page code list of supported VPD information
80	Device serial number
C0	Operation mode

Furthermore, if page codes other than those shown above (VPD information that is not supported by the IDD) are specified in the CDB, that command is terminated with a CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid field in CBD [=24-00]).

The format and contents of each type of VPD information are shown below.

a.Page code list

This VPD information reports the page code list of VPD information supported by the IDD. The format of this VPD information is shown in Figure 3.3.

Byte	Bit	7	6	5		4	3	2	1	0
	0		Qualifier				Device Type Code
	1				X‘00’ (Page Code)
	2				X‘00’
	3				X‘03’ (Page Length)
	4				X‘00’ (Page Code List)
	5				X‘80’ (Device Serial No.)
	6				X‘C0’ (Operation Mode)

Figure 3.3 VPD information: VPD identifier list

The values indicated in the "Qualifier" and "Device Type Code" fields in byte 0 are the same as those in the previously mentioned standard INQUIRY data. The "Page code" field in byte 1 indicates the page code (X '00') of this VPD information itself. Also, the "Page length" field in byte 3 indicates the length (byte length) after byte 4. This value has no relationship to the specification in the "Transfer Byte Length" in the CDB, but indicates the length of this VPD information and is always X '03' (Total data length = 7 bytes).
