Maybe I'm missing something here but isn't FCP-4 at a layer above the
FC-LS fibre channel layer and somewhat independent?  If it's a FCP-4
layer detected unknown exchange then the reason code returned
corresponds with the FCP-4 layer (logical error), and if it's a FC-LS
layer detected exchange unknown then the FC-LS layer code is returned
(Unable to perform command request).

Subject: FC-LS/FCP-4: REC ELS reason code inconsistency
* From the T10 Reflector (t10 at t10.org), posted by:
* "David Peterson" <dpeterso at brocade.com>
*
FCP-2/3/4 error detection implementers,
FC-LS and FCP-4 are inconsistent regarding the proper reason code to
return if the Originator S_ID,=20 OX_ID, or RX_ID fields are
inconsistent (i.e., the Exchange is unknown).
FC-LS specifies the reason code shall be 09h "Unable to perform command
request". Note this reason code has been specified since FC-FS.
FCP-4 specifies the reason code shall be 03h "Logical error". Note this
reason code has been specified since FCP-2.
Please respond indicating the reason code you return and/or expect if
the Originator S_ID,=20 OX_ID, or RX_ID fields are inconsistent, along
with any associated specific reasoning.
And please respond by end of business March 30th so I can address this
issue at the April T11 meeting week.
Thanks...Dave
