Re: z/VM 3 and IFL engines - Oh No!
It is also my understanding that you have to buy another VM license to run guests under your IFL engine when you get it. The IFL VM will have to talk to the NON-IFL VM via an intra-LPAR communications technique. Alan Altmark posted that z/VM 3 can't run in IFL engines. This is not good news for us. We are currently running VM on a machine that can't run z/VM 4. We are looking at getting newer machine with an IFL engine. We wanted to do a Linux proof of concept on the new machine, on the IFL to isolate the linux workload. If z/VM 3 can't run on an IFL we'll have to upgrade VM - but after we get the new machine since our current machine can't run z/VM 4. So my question is can z/VM 3 really not run in an IFL, or is this another license issue? We already are pursuing RACF licensing and I now see we'll need a special bid for RSCS NJE and/or Passthru. Can the z/VM issue also be pursued as a licensing issue or is this one real? -- Rod Clayton KA3BHY Systems Programmer Howard County Public Schools [EMAIL PROTECTED]

Re: z/VM 3 and IFL engines - Oh No!
Ann, You can have the IFL added to your system, and use PR/SM to create several LPARs that share the processor resource, and don't use VM at all until your hardware and software portfolio match up to allow that. That should at least allow you to get started on your proof of concept.

Re: z/VM 3 and IFL engines - Oh No!
Are both machines going to be on the floor together for a while? If so, will there be enough time to migrate your VM workload to the other system and start your Linux POC after your VM migration?

Re: z/VM 3 and IFL engines - Oh No!
Ann, If you try to IPL any version of z/VM prior to z/VM 4 on an IFL, the processor will check stop on you. It's definitely not just a licensing issue, it's a real limitation put there by IBM so that they and the ISVs could feel safe in not counting the processing capability of an IFL towards the machine group size, and hence not increasing the group-based software charges.

Re: z/VM 3 and IFL engines - Oh No!
Keeping both machines could incur additional software and hardware costs. For now, I just need IBM to verify z/VM 3 really can't run in an IFL. If it really can't, we'll just have to deal with it.

Re: z/VM 3 and IFL engines - Oh No!
I don't really see much of a problem here. Since the IFL engines can't be mixed with S/390 engines. You end up running the S/390 in seperate LPARs from the IFL engines. Buy the new box. Move your current z/VM 3 on the S/390 engines. Install z/VM 4.2 on the IFL side. Do the Linux proof of concept, on the IFL side. You may, at this time, when you buy z/VM 4 for the IFL engines, also buy it for the S/390 engines and run your z/VM 3 under SVC for up to a year. BTW, we got z/VM 4.2 a lot cheaper than $45K when we bought a MP3000. If we would have known to bid our current VSE operating system at that time, we could have received a discount on VSE/ESA for the first year also. I don't know if z/OS can be discounted or not. But in any case, find out before you sign the deal on the hardware. Tom Duerbusch THD Consulting Ann Smith wrote: Alan Altmark posted that z/VM 3 can't run in IFL engines.

Re: z/VM 3 and IFL engines - Oh No!
And, if I may ask, what do you need RSCS and PVM for that cannot be handled by FTP or Telnet? (Given that this is a Linux workload, not traditional apps.) One thing might be that they're integrating a set of pre-existing management tools to cover the VM side of the new box -- not too uncommon to ship all the console logs for TCP and OPERATOR over to one system so you don't have to do automation in multiple places. FTP is difficult to automate (as you've seen over time), and the current telnet client doesn't have scripting built in like PVM does -- although a TCPIP line driver would be a nice extension to PVM. Hmm. Where did I put that requirement form.. -- db
