Re: NFS mounted directory
Mark, Sorry for the late reply. 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!

Re: NFS mounted directory
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.

Re: NFS mounted directory
Mark, Thanks for the update. I just noticed your name on the cover of the Redbook. Actually, the company bought the book - all $58 worth plus shipping. If you want to borrow money, you can ask my boss, but I think I know the answer. I hate reading Redbooks with Acrobat reader. I much prefer book manager, but most redbooks are only in PDF format. I prefer books I actually read on paper. Like I said below, I don't have the best eyesight. If I'm searching for something, bookmanager is great for searching a book, or a whole bookshelf. I think I have enough to do the IOCDS now. I can try the HCD command to test if the install will work dynamically, and then install it if the test works. That won't hurt anything. Otherwise, I'll do it Saturday with our normal IPL of z/OS. Eric [EMAIL PROTECTED] 03/11/03 03:13PM Eric, You _bought_ the Redbook? Wow.

Re: NFS mounted directory
Eric, There are no Linux/390 distributions that include the CLAW driver in the installation starter files (yet), so that isn't an option. Yes, you can hook two ESCON channels together to get a communication path going. It's a _little_ more involved that what you said, but not a lot. You need to make sure that the two ends of the connection are not both genned as CTC (one end has to be CNC?), routing will be something that needs attending to, etc. You won't be able to use the MVSNFS facility to NFS export the files, since that requires authentication stuff that won't be on the initrd.
