Eric, You _bought_ the Redbook? Wow. You're the first person I've known to have bought one after they became available for download.
Can I borrow some money? :) No, we didn't document hooking up CTC connections. We had enough work to do as it was. You shouldn't have to worry about the CHPID and Control Unit definitions. They should already be there. You may need to make the one you select available to the Linux/390 LPAR. The CTCs are defined as type "SCTC" (ESCON CTC). Define the connections in even/odd pairs (read channel/write channel). The connections are paired up from CTC FC side to CNC/FCV or FC side. Make sure that in _one_ place, you make sure that the read/write channels are swapped so that you don't wind up with a read channel hooked to a read channel, etc. This would probably be easiest to do in the MVS TCP/IP parms, but you can also do it by telling the chandev layer in Linux that the device numbers are the odd number, followed by the even number. I'm not sure about the dynamic loading of the gen. I'm not really a hardware guy, and we've seen problems with people doing that in the past. As I recall, if you do it, you need to configure the stuff online from the service console, since Linux doesn't have the equivalent of a "config online" command yet.

Actually, I have formulated a plan of action, which I will share. I also have some questions I'm still not sure of. I have decided to get the RedHat 7.2 S/390 distribution. I will download it from a RedHat Mirror site someone posted last week. Is 7.2 the current RedHat S/390 distribution? From everything I've seen, I believe it is. Hopefully, this weekend, I will install the IOCDS change to our MP3000-H50 for connecting 2 Escon channels with an Escon cable. I'm still not exactly sure how to define each CHPID, the Control unit, and Device definitions. I actually purchased the SG24-6264 redbook you listed below, but I couldn't find a definition for the CTC connection. They only show the OSA connections. If I'm not seeing the examples (very possible - I was deemed to have vision of 20-Nil by my army physcial - which kept me out of Viet Nam), please give me a page number in the book. One last question. Can I dynamically install the IOCDS with the CTC connections? There is nothing defined on the two Escon chpids I would be using. I've decided that I need to get a Linux system for my PC at home. I don't really like the idea of dual boot, but I think it would give me a great toy to learn all of the commands on, and something to play with that wouldn't harm anything. Actually, that might be a good excuse to buy a laptop. Now all I have to do is convince the wife!

Just to recap, you are dead in the water until you can get a CTC connection to your production LPAR. That is the only way you're going to get a working network with the current distributions. Once that is done, you'll probably want to refer to the "Linux for IBM zSeries and S/390: Distributions" Redbook, SG24-6264. It's pointed to from the top of the main page at http://linuxvm.org/ . That has step by step instructions for doing what you need to do after you get the network up, and is more current that the document you've been using.
