All:
One of our CPUs (z800 box) was recently set up with z/VM 5.1, not in LPAR mode. The trouble is that we run several 2nd-level VMs and the performance on that box has been miserable (some of the VSE machines had to be moved off, due to performance problems).
From my reading, I have gathered that the correct way to handle this is to put the 2nd-level VMs (and their VSE systems) on their own LPAR.
My question: never having been involved with LPARs, how difficult (or easy) is it to be able to move devices from one LPAR to the other quickly? That is my main concern. We have multiple CPUs and need to be able to move tape, disk, and printers around quite often. And, in the same CPU, we often need to mode OSA connections. Is all of this doable?
