Gordon, You cannot have both S/390 and IFL processors in the same LPAR. That is not supported. Or did I misunderstand what you were trying to do?

Sorry for the duplicates. About two months ago I wrote to this list asking about how to set up VM to run on an IFL processor. We've finally got z/VM 4.2.0 up to where we can IPL it in a new LPAR. We have a 9672-r36 with an IFL engine and we want to run it in the new LPAR on a dedicated IFL engine. In the HMC we've defined the LPAR to be "Linux Only" in the General tab of the LPAR image profile. Activating the image profile we even get a cute little icon with a penguin on it in the list of CPC images. However, it will not IPL if we set up the processor for the LPAR as "dedicated central processors" on the "processor" tab of the image profile (says no processors are available and to free one up from the other LPARs). It -will- IPL if we set this up as "dedicated integrated coupling facilities processor". So far, so good. However, looking at the SAM monitor shows CP0 CP1 and CP2 (our 390 processors on this box) active, but CP3 as not active. Furthermore, if we start a program on the Linux/zVM420 LPAR running that chews up CPU time - VM in the LPAR shows 94% active - we note that CP0, CP1 and CP2 increase their bars in the SAM monitor and CP3 does not. If we stop the program, the bars return to normal. It appears that we are NOT running on the IFL engine! Has anyone actually gotten z/VM 4.2.0 to run on an IFL engine in a G5 processor? If so, how did you do it? "Never trust any computer you can lift."
