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).
Byte 4 and subsequent bytes list all the VPD information page codes supported by the IDD, with
the VPD page code indicated in ascending order in each byte.
b. Device serial No.
This VPD information reports the device serial number of the IDD. The format of this VPD
information is shown in Figure 3.4.
