z/VM Hardware Configuration Question
Hello, Everyone. This is my first post to this User Group. Thanks in advance for your help. I have a question... We are running five VSE guests under VM and recently experienced a hardware failure. This has led us to investigate the possibility of installing a spare so that we're not down if we have another failure in the future. Is it possible to configure an installed piece of hardware to be used (for redundancy) in case another one fails? Let's say that I want a FICON card that is not cabled up to be available for use, without an IOCP change (i.e. POR) in case the FICON card I'm using goes bad. I need it to be available to all the same devices as the one that's cabled and configured so that I can pull the cable off the bad and put it on the empty one. But the problem I've run into is the build of the IODF fails with the following message: *ICP ICP230I CONTROL UNIT 0440 PREVIOUSLY DEFINED Any help would be appreciated. Thank you, Sherry Sharon J.

Re: z/VM Hardware Configuration Question
I would cable it up and use it! Then if one fails you fail over immediately, no loss of I/O or downtime while our cabling up the new one.

Re: z/VM Hardware Configuration Question
Yes, it is possible under the right circumstances to have fail-over devices defined. One example that comes to mind is with OSA adapters and virtual switches. I've seen deployments of fail-overs for those components that work slick. Am curious why you would need to do this for something other than a communications port, though. Nearly all modern hardware has redundancy built into it already, which is why there are multiple paths to DASD, etc. Most mainframe configurations always have at least 2 of everything (FICON cards, etc).

Yes and no. :-) Yes: Storage controllers have the concept of multipathing. If you run multiple FICON cables from your DS8000, say, to your CEC, then the I/O subsystem handles failures semi-transparently. (The I/O goes through, but the host is notified of loss of a path.) Yes: OSAs that are given to a VSWITCH. CP handles the failover - the guest doesn't see it. No: Things like FICON CTCs do not have multipathing. Each cable represents a unique set of addresses/subchannels. If one of the CTCs fails, it will be noticed by the OS. It is up to the OS to manage the grouping. No: Dedicated OSAs. Failover is the guest's responsibility.

Re: z/VM Hardware Configuration Question
the processor itself used to be able to remap a chpid from one physical port to a different one, using the chpid mapping tool in the SE. You may need to have a CE / PE do the work, but I think it's still possible to remap a dud port to a functional one without having to rebuild your IODF. This is probably not exactly what you're looking for though, since it means you gotta call a service person to get it done. -- Jay Brenneman
