There
was a change made in draft 7 as follows:
- SCSI response made to fit having both
a Status and a Response
field. Needed for target errors that
result in a check
condition and ACA. In line with SAM2
that requires both fields
(former versions where modeled on FCP).
Can
someone give me a case where both response and status can be set together?
Also,
it seems that ACA is reported via status; so what is the referenced statement referring
to?
Also,
the spec says status “is valid only if the Response Code is Command Completed
at target”. So, that makes me wonder more about why they need to be separate. I
assume the initiator should check the response for 0 before checking the status
and then ignore the status if the response is not 0.
