If it's already partitioned, yes, to some extent. You can wait till
both partitions are powered down (should be able to see this from the
lights on the PCI-E slots). Then use ASMI to shutdown the hardware, if
it isn't configured to shut down automatically.

You can also configure both partitions for Autostart and to use LAN
console instead of the HMC console, and you'll be able to access the
console without a HMC.

You can individually restart partitions with a simple pwrdwnsys *YES and such.

Yeah, of course. The LPARs don't care much about the HMC being down.
