This sounds much better to me. Invest 30 min. and install a centos-5 to a 4G 
usb-stick. Put hpacucli and hpaducli on it and then you can configure, manage 
and diagnose any server you want.

Why would you make 5 logical drives? Why use partition tables?

I think hpacucli works fine but it sure would have been nice to be able to 
create flexible logical drives in the smartarray bios.
