    Re: Target Reset handling



    Julian,
    
    I was thinking that the C-bit would go into bytes 2/3 (currently
    reserved) of the SCSI Task Management Command PDU (as defined in 
    section 3.7 of draft-satran-iscsi-01.txt) - which does not have
    a CDB.  So, I guess it's part of the iSCSI protocol headers, as
    you were suggesting.
    
    Thanks.
