Why do you care what hdisk numbers get assigned to rootvg? It is mildly
annoying that they change, but it doesn't affect the system in any
meaningful way, assuming that the bootlist command still shows these new
disks as the boot disks. The above seems to me to be a lot of work and
potential for harm for a change that has no real benefits. A cost-risk
analysis says this is not worth it, IMO.
