(1) EVPD (Enable Vital Product Data)
a) If the specification in this bits is zero, the IDD transfers the standard
b) If the specification in this bits is one, product information called VPD
(2) CmdDt (Command Supported Data)
a) If the specification in this bits is zero, the IDD transfers the standard
b) If the specification in this bits is one, the IDD transfers the command
(3) Page code / Operation code
a) When the "EVPD" bits is one, this field specifies that the IDD transfers
b) If the "EVPD" bit is zero and the "CmdDt" bits is one, this field specifies
(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
Table 4.1 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.
