If both EVPD and CmdDt are set then the drive will return CHECK
CONDITION status with a sense key of ILLEGAL REQUEST.
If CmdDt is set and EVPD is clear then the drive will return the
Command Support Data for the specified operation code (see
Support Data on page 59).
If the EVPD flag is set and the Page Code is not zero and there is a vendor
defined Inquiry Data Page corresponding to that page code, then that
page is returned. Otherwise, Check Condition status is returned. The
Sense Key is set to Invalid Request (5) and the additional Sense to Invalid
Field in CDB (2400).
The command returns Standard Inquiry Data in the format
INQUIRY
shown in table 25.

The Standard Inquiry Data is based on the SCSI 3 standard for Standard
Inquiry Data. This allows for setting certain bits in byte 6 to indicate
features that were non-standard in SCSI 2. The only supported SCSI 3
field is Multi Port (MultiP).
The Multi-Port (MultiP) flag is set if the device has multiple interface
ports. Parallel SCSI devices do not have multiple interface ports and have
this flag clear.
The 16 Bit Address (Addr16) and Wide Bus 16 (WBus16) flags are set
depending on whether the hardware supports these bus features. These
flags are only valid for Parallel SCSI and are clear for all other interfaces.
