    Julian,
    
    Can a Logout command PDU be originated by a target ? If so,
    this would eliminate operations like the target sending AEN
    with an iSCSI Event Indicator of
    "Target Requests Logout on this connection".
    
    In general, what is the policy of the iSCSI draft towards
    un-solicited inbound command PDUs received by an
    initiator. Which of the following commands
    can an initiator receive  :
    
    1) Login Command
    (Could be received during device discovery process when
    another initiator  on the SAN is discovering its devices.)
    
    2) Logout Command
    (Could be originated by targets as a form of error recovery.)
    
    3) Text Command
    
    4) NOP-OUT Command.
    (Could be originated by a target to test a connection or to
    request DataRN acknowledgement, when the max un-acknowledged
    DataRN limit has been reached.)
    
    Specifc elaboration in the draft of the commands that targets are
    allowed to originate would be desirable.
    
    Thanks,
    Santosh
