9.3.1 Inquiry Vital Product data
Instead of the standard Inquiry data shown in Table 7, the initiator can request several Vital Product Data
pages by setting the Inquiry command EVPD bit to one. The SCSI, Version 2 Interface Product Manual P/N
77738479, section 5.1.1.3.1 lists the Vital Product Data pages and describes their formats. A separate Inquiry
command must be sent to the drive for each Vital Product Data page the initiator wants the drive to send back.
