Shimon Thanks for the assistance. After pulling a little more hair out I finally got the LPAR CTC links to work. In the process I ran into a few things I still don't quite understand.
When I got the CTC's properly defined, I ran into a situation where I could get both sides to bring the links ready and set up the gateways between them but could not Ping across the LINK. After trying about every order of bringing up the links I restarted both stacks and took the START statements for the DEVICEs out of the PROFILE TCPIP files on both systems. I was then able to run an OBEYFILE on both sides to START the DEVICEs and things worked fine. I've never run into a case where order of starting the LINKs gave problems. BTW, the first TCp/IP was at Z/VM 4.4 level and the second was as Z/VM 5.2 level. (It took me a while to notice the syntax in the 5.2 Gateway statement had changed.) Is there a command to stop a DEVICE so you can reissue a START again without restarting TCP/IP? Z/OS TCP/IP has a VARY command for this sort of thing. --------------------- Also , on the redundant paths mentioned below. > >Ok, all CUs and DEVs defined on channel 02 and channel 03 will be >accessable from all three LPARs.

Its been a while since we've run LPARs. The IFL and some isolation issues on Z/OS forced us back to LPAR's again.
