Hello Eric, Yes, I believe the two mainframes were connected to the same VLAN subnets. The client had no problem accessing the new CPU without VIPA/MPROUTE. Beyond that I don't know the answers to your questions. Something to ask the network people. Thanks, Mike

It could have been a ARP/MAC timeout issue? Are the MAC's locally administered on the mainframe? You may have private VLAN or some other mechanism setup to limit the host interactions on the switch.

Sorry. =20 Anyways, we had new cables attached from the OSA card on the new CPU = attached one to our switch, the other to the switch for the client. No = new cabling was done at migration time. We tested before the migration = and all well, non-VIPA.=20 =20 Thanks, =20 Mike=20 ________________________________ From: The IBM z/VM Operating System on behalf of Davis, Larry (National = VM/VSE Capability) Sent: Wed 15/12/2010 8:34 AM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Problems with MPROUTE going from z800 to z9BC computer Are you using the same or New Network connections to the network.

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 =3D 540RES, XXXPAG =3D 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?
