    RE: Question regarding SNACK and bidi transfers



    It wouldn't really have to be repeated but I don't think 9.8.1 and 9.7 should say something other than "(starting with 0").
     
    I just didn't know the best way to suggest the clarification.
     
    Maybe something more light, like "except when used with bidirectional commands (see section 2.2.2.3)".
     
    The problem with a blanket statement like "(starting with 0)" is that one can easily miss the other section contradicting it.

    Eddy,

    In fact 2.2.2.3 contains:

    For bidirectional commands, the target uses the DataSN/R2TSN to sequence Data-In and R2T PDUs in one continuous sequence (undifferentiated).

    Do you think I should repeat this in 9.8.1 and 9.7 ?

    Julo

    Julo,

    Since the answer to the 2nd question is "yes" (see your EMAIL with subject
    "Emailing: msg10874.txt"), then I think the spec should make that more clear
    in sections 9.8.1 and 9.7.

    Perhaps in section 9.8.1, it should say something like "Except, when used
    with a bidirectional command and SNACK is being supported, the R2TSN must
    start with a number that couples the R2TSN and DataSN together as one
    continuous sequence". And a similar statement added to 9.7.

    Eddy

    I have a question about SNACK type 0 requests. In the text, they are
    described as being for Data-In PDUs or R2T PDUs.

    For a bidi command, how do you know which? Does this mean that for a bidi
    command, data-in and R2TSNs have to be mutually-unique (i.e. drawn from
    the same pool)?

    Take care,

    Bill
