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 Interface Product Manual, part number
77738479, 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.
Table 8 shows the Vital Product Data pages for the drives of this product manual. “Y” means reporting that particular
parameter is supported, but it may be different for each drive.
