Michael, Make sure you have the SuSE IUCV2 kernel installed. That was supposed to include some fixes to make things like this work better. Once I got a connection established, things seemed to work fine, it was just getting one started that was a problem. I don't recall ever trying to set up an IUCV connection to the VM TCP/IP service machine.

I did manage to make a connection by starting them up in rapid succession, as you suggested. I had heard the IUCV was a little shaky at times, but I had no idea that it was this bad. Does it suffer these same problems communicating with the TCP/IP stack or is it just other Linux images? Michael L. "Post, Mark K" <mark.post@eds.com> 12/18/2001 08:46 PM EST Michael, I ran into a similar problem during the RedBook residency. I had a very difficult time getting two Linux/390 guests to talk over an IUCV link. Basically, I wound up taking both sides down and then starting them very close in time to each other until they seemed to "synch up." It was very aggravating. Some people have commented on how much more reliable IUCV connections are between Linux/390 guests, but I've always had better luck with vCTC connections.

I did as you suggested and now the device iucv0 is active. However, I'm still not able to connect with another image in VM. Earlier, I neglected to mention that i'm trying to set up an iucv connection between two linux images under VM. We used this connection to retrieve the installation files. Now i'm trying to reestablish that communication. The older image (SuSE) still has the same iucv setup as during the installation process. I have the vm usernames declared in the parm files and active iucv devices, but no connection. The SuSE side produces the log message "kernel: iucv0 : connection to user redhat is down" whenever I attempt to ifconfig iucv up on it. Now that I've followed your advice, the red hat side produces "kernel: iucv0 : connected with remote side" when I bring it up. Any ideas? Michael Lambert >Did you add a REMIP entry in this file ?
