If bytes 1, the "EVPD (enable vital product data)" bits, the "CmdDt (Command Support Data)" bits, and byte 2, the "Page code" field in the CDB are enabled only in the case that transfer of the SCSI-2/SCSI-3 mode's INQUIRY data is specified. In the case of the SCSI-1/CCS mode, zero must be set in these bits and in this field. And if both the "EVPD" and "CmdDt" bits are one, this command is terminated by a CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid Field in CDB [=24-00]).

(1)EVPD (Enable Vital Product Data)

a)If the specification in this bits is zero, the IDD transfers the standard INQUIRY data or the command supported data, mentioned later, to the application client.

b)If the specification in this bits is one, product information called VPD (vital product data) is transferred to the application client.

(2)CmdDt (Command Supported Data)

a)If the specification in this bits is zero, the IDD transfers the standard INQUIRY data, mentioned later, to the application client.

b)If the specification in this bits is one, the IDD transfers the command supported data, mentioned later, to the application client.

(3)Page code / Operation code

a)When the "EVPD" bits is one, this field specifies that the IDD transfers the kind of the VPD information.

b)If the "EVPD" bit is zero and the "CmdDt" bits is one, this field specifies the operation code (CDB byte 0) of commands generated command supported data.

(4)Transfer Byte Length

Byte 4 of the CDB, the "Transfer Byte Length" field, shows the number of bytes of standard INQUIRY data or VPD information that the application client can receive by this command.

The IDD transfers data with the byte length specified in the "Transfer Byte Length" field, or the byte length in the standard INQUIRY data or VPD information which it is holding, whichever has the smallest number of bytes, to the application client. When zero is specified in the "Transfer Byte Length" field, this command is normally terminated without anything being transferred.

(5)Standard INQUIRY data

Figure 3.1 shows the format and contents of the standard INQUIRY data transferred to the INIT by this command if "0" is specified in the "EVPD" and the “CmdDt” bit.
