VPD information: device serial No.
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 '80') 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 '0C' (Total data length = 16 bytes).
