I do not see anything about ping/nop timeouts in /var/log/messages. I did a tcpdump during a failed connection and a successful connection. Unfortunately, I am not certain how to interpret the results. However, I do see "nop" in these results for the failed connection. This tcpdump was done when I know the connection was not working: Failed: 21:56:57.597808 IP ndsfdh1-iscsi.whoi.edu.47753 > ndsfnar1p2.whoi.edu.iscsi-target: S 1049711648:1049711648(0) win 5840 <mss 1460,sackOK,timestamp 963230000 0,nop,wscale 7> 21:57:03.658197 IP ndsfdh1-iscsi.whoi.edu.47754 > ndsfnar1p2.whoi.edu.iscsi-target: S 1069029545:1069029545(0) win 5840 <mss 1460,sackOK,timestamp 963236060 0,nop,wscale 7> 21:57:06.657769 IP ndsfdh1-iscsi.whoi.edu.47754 > ndsfnar1p2.whoi.edu.iscsi-target: S 1069029545:1069029545(0) win 5840 <mss 1460,sackOK,timestamp 963239060 0,nop,wscale 7> 21:57:12.658069 IP ndsfdh1-iscsi.whoi.edu.47754 > ndsfnar1p2.whoi.edu.iscsi-target: S 1069029545:1069029545(0) win 5840 <mss 1460,sackOK,timestamp 963245060 0,nop,wscale 7> This is the tcpdump from when the connection seemed to be working fine: 22:00:00.648924 IP ndsfnar1p2.whoi.edu.iscsi-target > ndsfdh1- iscsi.whoi.edu.45937: . 365633:367081(1448) ack 5901 win 49438 <nop,nop,timestamp 220290 963413046> 22:00:00.648931 IP ndsfnar1p2.whoi.edu.iscsi-target > ndsfdh1- iscsi.whoi.edu.45937: . 367081:368529(1448) ack 5901 win 49438 <nop,nop,timestamp 220290 963413046> 22:00:00.648935 IP ndsfdh1-iscsi.whoi.edu.45937 > ndsfnar1p2.whoi.edu.iscsi-target: . ack 368529 win 1525 <nop,nop,timestamp 963413047 220290> 22:00:00.648940 IP ndsfnar1p2.whoi.edu.iscsi-target > ndsfdh1- iscsi.whoi.edu.45937: . 368529:369977(1448) ack 5901 win 49438 <nop,nop,timestamp 220290 963413046> 22:00:00.648946 IP ndsfnar1p2.whoi.edu.iscsi-target > ndsfdh1- iscsi.whoi.edu.45937: . 369977:371425(1448) ack 5901 win 49438 <nop,nop,timestamp 220290 963413046> 22:00:00.648950 IP ndsfdh1-iscsi.whoi.edu.45937 > ndsfnar1p2.whoi.edu.iscsi-target: . ack 371425 win 1525 <nop,nop,timestamp 963413047 220290> 22:00:00.648955 IP ndsfnar1p2.whoi.edu.iscsi-target > ndsfdh1- iscsi.whoi.edu.45937: . 371425:372873(1448) ack 5901 win 49438 <nop,nop,timestamp 220290 963413046> We have one dedicated network adapter on the linux machine connected to the network. We have one network adapter/iscsi port on the Promise array connected to the network. If this means "1 session" , then yes. The promise array and the linux machine are on different subnets (is this what you mean by the same network?") No other machines should be accessing the raid array. As far as "target portal" I assume this means the Promise array? thank you for your help. -Jonathan -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
