Vital product data pages
The initiator requests the vital product data information by setting the EVPD bit to one and specifying the
page code of the desired vital product data. If the disc drive does not implement the requested page it shall
return CHECK CONDITION status. The sense key shall be set to ILLEGAL REQUEST and the additional
sense code shall be set to INVALID FIELD IN CDB.
This section describes the vital product data page structure and the vital product data pages that are appli-
cable to the disc drive. These pages are optionally returned by the INQUIRY command and contain specific
product information about the disc drive. The vital product data includes unit serial numbers, device operating
definitions, firmware release numbers, servo ROM and RAM release numbers and the date code from the
manufacturer’s defect log.
