Julo "BURBRIDGE,MATTHEW (HP-UnitedKingdom,ex2)" <matthew_burbridge@hp.com> @ece.cmu.edu on 13-09-2001 20:33:30 Please respond to "BURBRIDGE,MATTHEW (HP-UnitedKingdom,ex2)" <matthew_burbridge@hp.com> Sent by: owner-ips@ece.cmu.edu To: "'eddy_quicksall@ivivity.com'" <eddy_quicksall@ivivity.com>, ips@ece.cmu.edu cc: Subject: RE: iSCSI-countdown to new version Hi Eddy, The last part of the sentence was added just to highlight that if the first full feature phase commands were immediate then it does not increment the CmdSN. I would therefore proprose: Command numbering starts with the login request on the first connection of a session (the leading login) and includes every non-immediate command issued afterwards including into the full feature phase. The first login must be immediate otherwise if it is queued and there is a missing PDU earlier in the command queue then the login will not get processed. If the login was for recovery we have stalemate!

The reason it works better is because all login commands have to be immediate (with the correction you have stated). BTW, I thought the reason for the very first login to have the I = 0 was so hardware does not have to worry about the leading login and will just always advance CmdSN for the next Immediate command. Does Julian know the leading login is supposed to also be Immediate?

Also, if all other login phase PDUs MUST be immediate, Section 1.2.2.1 needs change because it clearly implies the opposite.

Therefore 1.2.2.1 is correct.

But 2.12.2 says: Login MUST be issued as an immediate request (I=1) except for the first Login request (C=0) of the leading connection that MUST have I=0. Since all commands during login must have the I bit set, I believe 1.2.2.1 3rd line should read command issued afterwards in full-feature Am I correct? Eddy
