RE: Concensus Call on Urgent Pointer.

["HAAGENS,RANDY (HP-Roseville,ex1)" <randy_haagens@hp.com>]

I disagree with making a solution to the framing problem optional.

The framing problem is real.  Without a solution to it, iSCSI will fail.
Failure is not an option.

Those who doubt the importance of finding a solution to the framing problem
should argue that point directly, without trying to negate proposed
solutions by making them optional.

Those who accept the framing problem, but disagree with the urgent pointer
mechanism as a solution, can contribute constructively by (a) exhibiting an
alternative solution; (b) fully explaining their reservations about use of
the urgent pointer mechanism.

I myself am not yet convinced that the urgent pointer mechanism is a viable
solution to the framing problem.  But I do applaud Matt's attempts to find a
solution.

I agree with Daniel smiths wording.

Neither the target or the initiator must support it but either or both can
request it.
The requested party does not have to support it to be complient.
