You do not have the iser_cmd_handler event numbers memorized yet :) Me neither :( It looks like the target disconnected and there was some sort of iser connection error because the ib_conn state is ISER_CONN_DOWN. The iser guys can diagnose it better for whatever kernel you are using. What you have here is connection established (event 9) and then disconnection (event 10). I suggest that you use logging with the iscsid user space daemon to realize better what went wrong. The way I do this is: start the service, then logout, then kill the daemon, run it again with logging/debug prints open and login manually. run$ iscsid -d 8 -f /tmp/iscsid.log 21 login$ iscsiadm -m node -T $target -l logout$ iscsiadm -m node -T $target -u As for the iser event numbers... it not iser but rather the RDMA CM events, they are present in include/rdma/rdma_cm.h at the kernel source tree.

For iser questions you should stick something about iser in the subject, because I do not think the iser guys read every email on the list. I added Eli and Or.

This is RHEL 5.2 w/ OFED 1.3 built on top of it. I know it comes bundled, but it did not work. I am using whichever Open iSCSI comes bundled w/ OFED 1.3. Also, I remember I had to update the tcl pkg for some reason? Other than that, stock kernel and libraries. Is this related to the other issue you posted about on Monday? I did not see a reply.

I'll explore from this side (I was thinking it had to do w/ some iSCSI parameter, but maybe I'm just blowing up the RC channel for no good reason).
