You're right, it's simple. That said, it's not obvious. But since you're just subbing, all is forgiven. :-) Each HiperSocket chpid is its own LAN segment. They are not bridged together. So the hosts using E8 have to go through a *router* (e.g. Linux, z/OS, z/VM) to get a host attached to E9 or EA. If you run out of triplets, you need to define more.
