I followed the howto http://tldp.org/HOWTO/SCSI-Generic-HOWTO/scsi_snd_cmd.html to pass through scsi cmd with data (self defined,target can handle it) to iscsi disk. however,the request was handled six times ,I checked the log ,the reason is shown below. The connection failed and recovered six times ,and I tested many times ,each time ,the same :six times! I'm newbie to scsi program. Any idea that can cause this problem ?
