    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!
    
    Cheers
    
    Matthew

    I'm not a good writer but I would write it as:
    
      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.
    
    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?

    Eddy,
    
    I think I may be missing something here: what would you suggest the wording
    to be?

    Because it says "afterwards whether during login".

    Hi Eddy,
    
    Why does 1.2.2.1 need modifying?

    So a correction is needed in 2.12.2.
    
    Also, if all other login phase PDUs MUST be immediate, Section 1.2.2.1 needs
    change because it clearly implies the opposite.

    Hi Eddy,
    
    IMO 2.12.2 is incorrect and the initial login command MUST be immediate as
    are all other login phase PDUs.  Therefore 1.2.2.1 is correct.
    
    Cheers

    Section 1.2.2.1 says:
    
      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 whether during login or in full-feature
      phase.
    
    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
