The above comments are questioning whether to use REJECT PDU (as defined in
section 2.19) or to use the "reject login" Login response PDU. It seems like
there's redundant solutions being provided here. The "Status" field in the
Login Response should be removed since a login reject should be conveyed
through the REJECT PDU.

Additionally, the above also questions the use of REJECT PDU for scsi PDUs
since their reject could do with more specific error information conveying
the reason for the failure. REJECT PDU would be desirable for use with
non-scsi PDUs along the lines of a standard LS_RJT for all ELS in fibre
channel.
