RE: iSCSI Text Request

["Julian Satran" <Julian_Satran@il.ibm.com>]

Eddy,

We did not think that it is worth having a variety of statuses for
different errors.
After a (relatively long) debate we reduced them to the current list.
It could have been shorter (as in the old Unix ?).
In any case your choices are the ones we had in mind too.

Regards,
Julo

A "protocol error" is only represented by a Reject and the login phase only
allows Login PDU's (see 2.2.3). So, I use a Login Response with status =
0200 (Initiator Error).

There should probably be more status's defined. For example, Section 5.1
(Login Phase Start) says:

        the target may reply with a Login Response indicating that it is
        unwilling to accept the connection without SecurityNegotiation and
        terminate the connection.

But the table in 3.13 (Login Response) does not give a status for
explicitly
that. So, I give 0201 (Authentication Failure).

Comments?

Dave,

You are correct: only Login Requests and Login Responses are allowed
during the login phase.  Until FFP, any other PDU is protocol? error.
The use of Text PDUs were removed when we revised the login procedure as
there were no benefits for using different PDUs (i.e. Text PDUs).

Before full feature phase is entered, is it valid for an initiator to
send a
Text Request PDU for parameter negotiation purposes?   In other words,
are only Login Request PDUs and Login Response PDUs allowed during
the login phase?

I believe iSCSI draft 9 only permits Login Request/Response PDUs
during the login phase, but we've noticed that some initiators violate
this restriction.
