Are you using the same or New Network connections to the network. Make sure the two OSA ports are not cross connected at the switch. If they are TRUNC'd together then you will have routing issues.
Just get a new set of IP's to test with on the new box, and get your network and firewall people involved.

We had this new machine for a couple of weeks and we created a copy of our z/VM 5.4 system on it (XXXRES = 540RES, XXXPAG = 540PAGetc...). I was able to test z/VM 5.4 and TCP/IP on it and it worked fine given that we were assigned new IP addresses for it. We have 2 TCP/IP stacks, one for our use, the other for the clients. For the client, on our production machine we use VIPA/MPROUTE. We could not test VIPA/MPROUTE on the new machine but static routing worked fine. We tried the OSA card in QDIO and non-QDIO mode and no problems. Connectivity for both us and the client. Come migration time however, we could not get the VIPA/MPROUTE functionality working. I could not ping from within the mainframe to anything beyond the OSA card. Tried both QDIO and non-QDIO mode. Our TCP/IP stack, no problems. We had to back out and now we have to try to set up a test VIPA/MROUTE setup and try it on the new machine. Waiting on the telecom architect for this. No changes to the configuration files were done (except for QDIO in the PROFILE TCPIP, but the same configuration files for non-QDIO). Any clues what could have gone wrong? Thanks, Mike Horlick CGI Montreal
