As other already mentioned, LPAR definition is the same for z/OS and z/VM (the distinction is between OS nad CF). OS config contains distinction between MVS and VM type. However, especially when using Linux under VM, it is worth to mention how to isolate MVS devices from VM. It can be done via Explicite device list - at LPAR level, while z/OS is usually filtered at OS config level. First method is at IOS level, while OS config can be changed on operating system (and Linux does not honor it).

IOCDS with VM and zOS LPARS

Re: IOCDS with VM and zOS LPARS
What I did was simply define the LPAR partition for VM on the Processor List screen using the P line command. When VM IPLs, it automatically discovers everything it has access to, so unless you have some unusual device VM cannot automatically identify, it's not necessary to create an OS definition for the VM LPAR. Coming from MVS, I was imagining this would be harder than it turned out to be. VM is much more advanced than MVS in this area in that it has (almost amazing) auto-discovery capabilities for attached devices.

While doing this, you can put the appropriate CHPs on the access list for the new LPAR. Then go into Operating System Configurations and create a new OS configuration. Make the Operating System Type equal to VM instead of MVS. Now create any new devices needed and put them, along with any required existing devices, on the access list for the new LPAR. Make a production IODF, then a IOCDS. Do a POR with the new IOCDS (unless on a z9?) to create the new LPAR. Define the LPAR characteristics on the HMC screens like you do for an MVS LPAR. Eg. the LPAR weight, the number of CPs to assign (shared/dedicated), the storage size, etc. Also, to be very blunt, you could just create a new z/OS type LPAR and OS configuration and IPL z/VM in it. The LPAR definations don't really care what OS (z/OS, z/VM, z/VSE, z/Linux) is running in the LPAR. All that I can see different between the MVS and VM values in Operating System Type is that MVS has an EDT associated with it and VM does not. Very high level, but there is really no real difference at the IOCDS level between the types of LPARs, other than a CF type LPAR. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its content is protected by law.

Re: IOCDS with VM and zOS LPARS
We run 2 VM and 2 z/OS LPARS on our 2086-170. I can get the IOCDS on Monday and send it to you. /Tom Kern /301-903-2211 --- Marc Holiwell [EMAIL PROTECTED] wrote: I am currently running two LPARs (with zOS 1.4 as OSes) on a IBM 2086 model A04(220), and would like to know if it is possible to create an IOCDS that will support an LPAR with VM as the OS, and another LPAR with zOS as the OS...???
