4-3.6.2 INQUIRY CHECK CONDITION Status
If an INQUIRY command is received from an initiator with a pending unit attention condition (i.e.,
before the target reports CHECK CONDITION status), the target performs the INQUIRY com-
mand and does not clear the unit attention condition. If an INQUIRY command is received after
CHECK CONDITION status has been presented for the unit attention condition, then the unit
attention condition is cleared and the INQUIRY command is performed.
CHECK CONDITION status is only generated for the INQUIRY command when the target can-
not return the requested INQUIRY data due to a hardware error or invalid INQUIRY CDB con-
tents.
Inquiry data is returned to the initiator regardless of the state of the selected LUN (e.g. NOT
READY, Non-Existent).
If the initiator requests a VPD page that is not supported, a CHECK CONDITION status with a
sense key of ILLEGAL REQUEST and an additional sense code of ILLEGAL FIELD in CDB is
returned.

nates the command with CHECK CONDITION status, the sense key is set to
ILLEGAL REQUEST, and the ASC/ASCQ is set to INVALID FIELD IN CDB
Specifies that the target return the optional Vital Product Data (VPD) specified by
