We just recently upgraded to a G5 processor and got an IFL engine with the other processors. Just last night I did an I/O gen with an IOCDS that created a separate LPAR that will run z/VM 4.2 and will eventually have all of our Linux servers as guests on this one z/VM LPAR.
We have just obtained z/VM 4.2 (currently running on z/VM 3.1.0 on our other LPARs) and so we can't test this new LPAR yet since we don't have a VM that will IPL on it yet. We have five other LPARs that share three 390 processors, but we want the Linux LPAR to use just the IFL processor. Since I've never done this before with an IFL processor, my question is, how do I tell the LPAR controls to use the IFL engine for this LPAR? When creating the LPAR image profile on the HMC console, under the "General" tab, I went into the "Mode" window and I see four choices there: ESA/390 ESA/390 TPF Coupling Facility Linux Only Do I choose the IFL engine by selecting 'Linux Only"? I don't see any other choice anywhere in the image profile that would indicate an IFL processor. Is there something else I have to do? Should I dedicate this processor to the LPAR? The only manual we have for the HMC is for our old G4 processor. I'd appreciate any help from someone who's done this before, or perhaps someone from IBM who's in the know.
