We have a Z/VM 5.2 TCP/IP connected to a Linux SLES 9 stack via CTC. We tested the setup with VCTC links and get connected ok. (LINUX in same LPAR). We moved the SLES system to another LPAR (again under VM) and attached a pair of real CTC paths to the systems to replace the VCTC links. When we do a NETSTAT OBEY STOP and START to bring the links up, the real CTC LINKs will come ready but will get unit checks (Sense 41) on the CTCs when any activity is initiated. We've tested the real CTC paths with RSCS to RSCS to see that we had a good pair of CTC addresses between the LPARs. The RSCS links work fine. Is there something unique in TCP/IP with real CTC links that we may have missed?
Thanks for any help. Ron Greve SDSU Admin and Research Computing
