SPC-3 section 6.12.1 says:
"The PERSISTENT RESERVE OUT command contains fields that specify a
persistent reservation service action,
the intended scope of the persistent reservation, and the restrictions
caused by the persistent reservation. The
TYPE and SCOPE fields are defined in 6.11.4.2 and 6.11.4.3. If a SCOPE
field specifies a scope that is not implemented,
the device server shall return a CHECK CONDITION status. The sense key
shall be set to ILLEGAL
REQUEST and additional sense code shall be set to INVALID FIELD IN CDB."


What if the TYPE field is bad (not implemented)?  Is ILLEGAL
REQUEST/INVALID FIELD IN CDB also the expected result?  Why is SCOPE
singled out here?  The SERVICE ACTION field could also have an
unsupported value.
