Yes. > > It sounds like the Persistent Portal is the one that we initially try to > log into, and the Current Portal is the one we get redirected to. Or is Correct. Persistent portal is the one returned by the discovery command. > that backwards? > > What happens if we discover the main (group virtual) portal, and our > Node record reflects that, then we get redirected? It seems like the Node record portal ip is the ip that the EQL box returns when you do discovery, and it is the persistent ip value you see in sysfs and when you run iscsiadm -m session. Note that if a driver does not support persistent_address attr then the persistent and current are both the currently logged into address. I think just older qlogic driver did not export this, but does now. Also, really old iser drivers did not export the non persistent address so they were both the same, but that was a long time ago. > Portal is going to differ between the Node record and the Session > record, which might explain what I'm seeing. It should match. Run iscsiadm -m session and iscsiadm -m session -P 1 and iscsiadm -m node .... your target/portal Does it show what it should? > > In this particular case, the problem occurs when Yast tries to step > through the Session records, doing an "iscsiadm -m node -I default -T > <iqn> -p <ip:port> -P1" for each session, but IPs does not match. > I am not sure what you mean. The iscsiadm -m node command above prints out the node record. What do you mean by session record? What gets printed when you do iscsiadm -m session/iscsiadm -m session -P $N? The iscsiadm -m session command prints the persistent address. See session_info_print_flat, so it should match what you see in iscsiadm -m node commands. Maybe you could cut and paste an example of what you mean it would help. -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
