Sometimes the hardest of problems have the simplest solutions. We ran some packet traces and confirmed that even with the CTCs out of the OSPF configuration they were still part of the source VIPA configuration. I really wanted to dedicate LPAR-LPAR traffic on the CTCs and leave the OSAs for normal network traffic. I am not going to mess with the qdio just yet because I must move this Linux LPAR to another processor in 2 months. I will revisit qdio at that time.
For now, I simply removed the CTCs from the z/OS source VIPA configuration. This allowed me to dedicate the CTCs for high volume LPAR traffic without affecting the OSAs and network usage. I pass this along for those like myself that sometimes miss the boat because we take too long to stop and smell the flowers. Our VIPA configuration was: HOME xxx.xxx.98.20 MAINPEPT 10.28.93.20 FE1 ; OSA Express Fast Ethernet card 10.28.91.20 FE2 ; OSA Express Fast Ethernet card xxx.xxx.86.9 CTCTP ;Test to Prod xxx.xxx.86.5 CTCTC ;Test to CEC ; PRIMARYINTERFACE MAINPEPT We simply moved the CTCs before the primary interface like so to remove them from the source VIPA configuration: HOME xxx.xxx.86.5 CTCTC ;Test to CEC xxx.xxx.86.9 CTCTP ;Test to Prod 1xxx.xxx.98.20 MAINPEPT 10.28.93.20 FE1 ; OSA Express Fast Ethernet card 10.28.91.20 FE2 ; OSA Express Fast Ethernet card ; PRIMARYINTERFACE MAINPEPT Additional packet traces confirmed that the CTCs are no longer part of the source VIPA. This has been working great. Thanks you all that pointed me in the right direction.
