Hi Marcy, I thought about the same idea... would you mind sharing your script? I was thinking about a script that would capture the CPU id and then it would activate the appropriate ifcfg-ethx and include it into the zipl.

What we do is use an init script to manipulate network config files based on the LPAR name we see in /proc/sysinfo. Would something like that work for you? We also do it to set identity at clone time.

I want to use Static VIPA and OSPF, with that said, I want to introduce an eth1 device. This second device will have an IP address at my DR site. At that DR site, there is a separate OSPF stub area. I want to define both eth on my golden image and clone from there. Has this ever been done? If so, do you guys have any suggestions as to how I can change my ospfd.conf to make this work? What I have below in red (if you have html turned on) is what I want to add for eth1, it is only available when the zLinux guest image and z/VM is physically brought up at my DR site: Static vipa = 1.1.1.55 Eth0 = 10.1.1.55 - OSPF stub area 10.1.1.0 Eth1 = 182.1.1.55 - OSPF stub area 10.0.0.0 ! -*- ospf -*- ! !
