I'll second this. In 20+ years of running VM, I can remember only two cases where something worked differently 2nd level than it did 1st level, and in at least one case, there was a reason for it. Unless you really have to be 197.34% paranoid about such things (you're launching missiles or

Good morning List, I have a question of general test and production architecture. We currently have some production zLinux guests running under z/VM 5.1. z/VM is installed as an LPAR on our single Z9 server. We had, until recently, a second Z9 on which I was running a test VM which I could

I would suggest the second LPAR approach, if anything for the separation of function. Until you can get it defined, you can certainly run the test VM second level. Moeur Tim C wrote: Good morning List, I have a question of general test and production architecture. We currently have some

I'm going to go with one of my favorite answers here and say it depends. There are pros and cons for both approaches. Some z/OS centric sites might feel more comfortable using the LPAR approach,as that might fit in better with their over all system management scheme. Running z/VM as a 2nd

1. Use what you are familar with. If it was LPAR on the test box, you may lean towards LPAR on your production box. 2. Many of the small to midrange shops never had LPAR. We always ran VM in basic mode, hence we would run VM under VM for testing. Now that IBM forced everyone to LPAR, the
