    Re: Another question of the obvious



    
    The general answer to your questions is "b." in both cases.  The SCSI
    Response PDU only shows that field as Reserved (with no other options).
    The only time that the LUN field is used with Data-In PDUs, is in
    relationship to setting the A-bit.  In that case it is set along with the
    TTT so that it can be returned with the SNACK.

    Subject:    Another question of the obvious
    
    
    
    Hi again,
    
    I've re-re-read (no, not a stutter) the spec and cannot determine the
    correct
    handling for the LUN field in the Data-In and/or Response pdus.
    
    If an initiator issues a SCSI READ10 command on LUN52 does the target set
    its
    LUN field in the Data-In pdu to:
    (a) 52 (ie same as what the initiator had)
    (b) 0   (treating it as reserved)?
    
    And does the target set its LUN field in the Response pdu to:
    (a) 52 (ie same as what the initiator had)
    (b) 0   (treating it as reserved)?
    
    Could the answers to the above change for different SCSI Commands?
    
    
    TIA,
    Ken
