    To: X3T9.2 Committee (SCSI)

    From: George Penokie (IBM)

    Subject: Maximum Burst Size Rounding Definition


    PROBLEM


    The current SCSI-2 Specification (Rev. 10) section 7.3.3.2
    Disconnect-Reconnect Page page 7-82 second to the last
    paragraph reads 'This value may be rounded as defined in
    6.5.4.'.   Section 6.5.4 states that if you round a parameter
    you must issue a check condition status.

    In the case of the Maximum Burst Size parameter what is being
    rounded is not the parameter but the result of the
    multiplication.  The multiplication is gives a result which
    may or may not fall on a boundary the device considers valid
    and therefore may round the multiplication result.

    I do not think this rounding should  result in a check
    condition as the original parameter passed is not modified.


    PROPOSAL

    The wording 'This value may be rounded as defined in 6.5.4.'
    should be changed to 'This value may be rounded to the
    nearest valid boundary condition.'
