The more we discuss this, the more it makes sense to install a LPAR if for nothing else but to test TLs. But the question is what do I have to allocate. My biggest problem would probably be the memory it usually runs at 99% and paging runs from 0 to 40%.

Also, what all does the LPAR share? The DVD drive? What about the tape library? Another problem could be I don't have enough disk space to replicate everything that is installed in production. We have a test environment but for some reason they installed it on the same machines as production.

Will the LPAR have to have its own IP address? I would guess so because it is "virtually" its own machine.

If I can come up with enough information maybe I can convince the "powers-to-be" how much safer and more secure it will be.

-Your architecture and AIX level must support LPARS
-You'll need a HMC
-Each partition requires a minimum of 192 MB (that's a "real world" value from my LPAR training)
-DVD drives, tape drives, and so on are "shared" between the LPARS, but are only attached to 1 LPAR at a time.
-You'll need enough disk to do a complete install of AIX, plus whatever you need to test your apps.

I suggest you go to IBM's site, look through the redbooks and read up on LPARS. Then inventory your current hardware and see if you are ready.
