RE: [Redhat-s390-list] RC2 beta iucv problem

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.

Thanks for the quick reply.

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?
