I fat-fingered, 03h is what is currently specified in FCP-2/3. As such
the query should be:=20
 =20
Please repond if you object to changing "Invalid OX_ID-RX_ID
combination" to 17h (i.e. not 03h) for FCP FC-4 Link Services, along
with your reasoning.=20
 =20
So Kevin, I believe you are indicating a change from 03h to 17h is ok
for you, since you already use 17h.=20

Sorry for any confusion...=20

Dave,=20

I disagree with changing this.  =20

My reasoning is that all IBM Tape drives use 17h and not 03h.  Also, =
03h
is already defined for Extended Link Services and while we do not use
it, some implementation out there might.  I understand that SRR is an
FC-4 Link Service and is neither a Basic Link Service nor an Extended
Link Service.  However, it is much closer to an Extrended Link service
in it's handling than it is a Basic Link Service.  This would force a
code change, and while that change would not be difficult it would =
cause
differences in behavior and expectations.  How will the HBA's react to =
a
change in the value of the response they get - and differences =
depending
on the device and code level?  Will this cause a change in their
behavior?=20

Thanks,=20

Below is an email that was discussed at the last FCP-3 working group.
The belief of the working group was that their implementations used 17h
for an "Invalid OX_ID-RX_ID combination" for the SRR FC-4 Link Service
(i.e., the same as for Extended Link Services).=20
=20
Also note that FC-FS/FC-FS-2 specifies a 03h for "Invalid OX_ID-RX_ID
combination" for a BA_RJT reason code explanation.=20
=20
Please repond if you object to changing "Invalid OX_ID-RX_ID
combination" to 03h for FCP FC-4 Link Services, along with your
reasoning.=20

Subject: Possible error in FCP3r03c document

Dave,=20
=20
I think I caught an error in the fcp3r03c document.=20
=20
In Table 17:=20

=20
The Reason Code explanation for "Invalid OX_ID-RX_ID combination" is
listed as a 03h.=20
However FC-LS lists this Reason Code explanation as "03h Service Parm
error - Initiator Ctl" and "Invalid OX_ID-RX_ID combination" is listed
as a 17h.=20

Am I missing something?=20
