Knowing the background, I would expect it consistently from a few
products and not at all from the rest. The important point is to be
prepared for it and handle it correctly.

I am aware of the footnote in FCP-4 and because it is a should there is
no guarantee that a PRLO will be sent. If it is sent, fine. But I would
certainly not expect it...

I would say the opposite, actually: A PRLO may be expected (though not
required) from the TPRLO responder to the TPRLO originator if the TPRLO
originator had an active process login with the TPRLO responder. This
resulted from accepting T10/04-383r2, and is reflected in FCP-4 table 4,
table footnote 6 (physical page 18 in FCP4r00a).
According to FC-LS subclause 7.2 fourth paragraph, the receiver of a
PRLO shall accept the request even if it has no active process login.
Based on the permitted reason codes for a PRLO LS_ACC, I would say the
reason code would have to be "Request executed".

No, the originator should not expect a PRLO from the recipient.
TPRLO has the same effect on the recipient Nx_Port as if all Nx_Ports
that have performed Process Login with the recipient Nx_Port for the
specified TYPE, performed PRLO with the recipient Nx_Port.
Thus no PRLO from the recipient is needed nor expected.

Would the originator of a TPRLO with the GLOBAL bit set to one expect a
PRLO from the recipient?
I would appreciate a reply.
