Nothing stopping you from deleting all partitions. Creating one partition
and assigning all resources to it. Install just the Lic and OS. Install
the disk sanitizer and go from there. This new partition should have 70
days of keys. Batteries on the disk cards shouldn't be a show stopper,
just make it run slower.
We have a 9117 MMA. (and two other power 6 boxes). And use HMC.
