Re: Detecting RHEL console disconnect/reconnect
Thanks Neale, I hadn’t thought of that. I can make that work.

Re: Detecting RHEL console disconnect/reconnect
Do you have Broadcom's VM:Operator, Velocity's zVPS, or IBM's VM Operations Manager (or even good old PROP)? If so, you could create an action routine that would intercept the DISCONNECT/RECONNECT message.

Detecting RHEL console disconnect/reconnect
With RHEL running on VM is there an interrupt or something that Linux can act on when the console reconnects or disconnects? If there were a vm event for those I could easily handle it outside Linux and invent my own trigger, but cp doesn’t pass those events to *vmevent :-( Maybe a udev rule to script something when either of those events happen. I could do some sort of polling thing that uses vmcp q userid to see if I’m disconnected or not, but that sucks and if that’s the only solution I think I’ll have to pass. Or settle for well under real-time action.

Re: Reconnect
Ron, If your emulator is assigned a specific slot on a HMC/ICC then the slot on the ICC has to be reset. If you are going directly into TCPIP and there are no specific exits that assign you to a particular terminal then I am not sure what your problem could be. Usually the first case above is the problem. Jim P.

On UNIX (thus on Linux) many of the best products live in their own "sandbox". Some call it a "product home directory". Others might call it a "package root directory". VM is a superb example of this where we enjoy Service Virtual Machines that not only can be isolated to their own minidisk (or two or more; it depends) but may also do so read only. (R/O sharing ... what a concept!) Substantial portions of the VM TCP/IP service machine suite can be made to run from a common PROFILE EXEC with the "product EXECs" invoked automatically. This is not how IBM ships VM TCP/IP, but it works VERY NICELY. Many many other VM based services run this way without being at odds with the vendor.

Ref: Your note of Mon, 21 Oct 2002 16:21:37 -0700 The equivalent commands in SuSE's way of doing things is "rcnetwork stop ctc0" and "rcnetwork start ctc0". Note that you may loose your default route with the ctc interface down, so you will probably want to enter "rcroute start" for good measure. Also note that even if you only have 1 network device, entering the device argument on the command avoids broadcasting the "Network is going down now" message. Bruce Hayden IBM Global Services
Re: Reconnect TCPIP
Two items: I can get the CTC's recoupled no problem. but: the "ifdown" and "ifup" commands are unknown on my SuSE 2.4.7 system. Where might I find them? also: I agree vlan's would be best. But if you don't have z/VM 4.3 yet, what can you do? We're in the process of installing, but it is unlikely we'll have it in production before February at earliest. (The boss decided it would be good experience for our new junior systems programmer to do 4.3 as his first install and everything is taking twice as long -- or more!) There are ptfs for vlans in 4.2, but those ptfs don't include the code for IP broadcast. Until we get 4.3 up we have to have an interim solution to this problem.

Re: Reconnect TCPIP
Gordon, You should only need to restart the ctc0 interface. Logon to the Linux system console and: ifdown ctc0 ifup ctc0 You may want to consider connecting your Linux servers to the VM TCPIP stack with VLANs instead using the HSI interface. If you do that, you won't have to restart anything when the VM TCPIP stack is restarted. There are a couple PTFs you may need for z/VM 4.2 to get it to work.

There are only 2 reasons to reboot a linux: changing the number of processors or changing your abount of memory. Everything else could be done without reboot. It is a linux. In worst case you need to shutdown all ctc-interfaces on that box, remove the ctc module, reload it and start the interfaces up again. You see, CTCs are not very reliable. The best virtual network interfaces at the moment are GuestLans. The reason for this is, they only "couple" to the interface and not to the guest at the other side of the interface. For this reason, if a guest dies, it doesn't matter to the others, except it stays down longer than the tcp timeout. And at all I claim there are no reasons to route a linux guest through the VM TCPIP. ;-) Greetings Oliver Paukstadt +++LINUX++ +++Manchmal stehe ich sogar nachts auf und installiere mir eins+++ ++
Re: Reconnect TCPIP
This question *really* surprised me, because I didn't even consider it a problem when we started up. I added an exec call in the TCPIP profile to "LINCOUP", and on the TCPMAINT 198 disk, I created "LINCOUP EXEC". In it, I have the Couple pairs needed to reconnect all the Linux images. While none of our images are under a severe load (we're just trying the waters, after all), this hasn't failed to work yet, and we've bounced TCPIP several times without incident or extreme interruption. (Sessions lost, sure. But the Linux images seem none the worse for wear once TCPIP is back up.) Our problem has been the other way 'round. Randomly, when we bounce a Linux image, TCPIP fails to recognize its return, and we have to send an OBEYFILE to restart the line. Robert P.

Re: Reconnect TCPIP
Gordon, I would think you would need to restart ALL the services that IP uses on EACH LINUX Image !! that could be a real pain to keep track of, or maybe you could restart ALL of the services !!! I do that on my desktop, but it runs Hercules & Sles7/390 A auto script that could be fired off from a session would be good, considering IF IP services take a hit you may not have Telnet like connectivity !!... let us know what you find out about this one, I would like to file the response away Thanks Ken Dreger At 03:15 PM 10/17/2002, Wolfe, Gordon W wrote: We have a number of Linux (SuSE 2.4.7) images running under z/VM 4.2.

Reconnect TCPIP
We have a number of Linux (SuSE 2.4.7) images running under z/VM 4.2. These are all connected to the VM TCPIP stack via virtual CTCA's. If the VM TCPIP stack comes down and back up, is there a way to reconnect the linux servers without shutting them down and rebooting?
