    Julian,
    
         I'm confused as to what field was removed in order to make
         the CDB field 16 bytes and locate the CmdSN at offset 24.
         Can you send the correct layout of the SCSI Command PDU
         when you get time?
    
    Thank You

    Thanks Daniel,
    
    It's fixed. CmdSN is at 24 and  the following are shifted.

    In section 2.3 SCSI Command...
    
    the table shows bytes 36--47 reserved for the CDB (12 bytes).
    But
    the description 2.3.6 says it's 16 bytes.
    
    (I'd prefer 16 bytes---I'm not a big fan of Stat/DataSN.)
    
    This document is getting big---but the latest version seems to be holding
    up
    well as I read through it.  Good work.
    
    Daniel
