That's one of my concerns.

It seems we're just speculating what purpose these codes were intended
to serve.  Not only don't we know for sure what that purpose was, we
also don't know if that purpose is actually achieved.

The other concern is that these codes could be interpreted to impose a
new requirement on targets to generate them in certain situations.  Of
course we don't know what those situations are, or why targets should
do this, but clearly someone could argue that those numbers exist and
therefore are supposed to be generated.

Unless there is a solid proposal that assigns a clear meaning, and
that meaning is valuable to initiators, I believe that the only
correct answer is to consider what happened as a glitch in the
standards process and remove, to the extent possible, the debris left
behind by that glitch.

I don't see anything in the recent discussion that gets us to this
clear meaning and useful purpose.  In particular, I see absolutely NO
trace of "rough consensus and running code" to support the notion that
the iSCSI standard should support these new codes.

David, can we put in motion the deprecation of these codes?
