David, Check with your DR provider. Although you may not have VM, they most likely do. I know that Sungard and IBM do. If so, you might be able to use their VM system for your DR. If so, then you don't need to do anything. Just tell the DR vendor your current addresses and have your DR Linux guest have those same addresses. I.e. run all your DR under VM instead of in LPAR mode. I'm trying to get our DR environment changed from LPAR mode to VM. But nobody else around here seems to care.
