    Re: iSCSI : Aborting non-SCSI tasks.



    Hi Charles,
    
    non-scsi tasks refers to Login, Logout, Text & NOP-OUT PDUs.
    
    Initiators will need to time these tasks [exchanges ?] and how do they
    deal with a timeout of such non-scsi tasks [exchanges/PDUs/commands] ?
    
    
    Regards,
    Santosh
