I have been searching SPC-4 to answer the question, "What is the correct
additional sense code to return if the SERVICE ACTION field contains an
unsupported value?"
One might think that since the OPERATION CODE field and the SERVICE
ACTION field are taken together to indicate a command that the correct
response would be INVALID COMMAND OPERATION CODE
However, with a strict reading of SPC-4, since it is silent on this
specific condition, the correct response is to use INVALID FIELD IN CDB
Does anybody disagree with my interpretation?
Thanks,
