If it does raid6 then you have a p400 or p800 controller, right? If so then
hpacucli or similar can easily give you a small logical drive for the OS and
then a large one for data.
On the small one partition normally and install grub.
On the big one do one of:
1) partition with parted and gpt
2) use lvm and put a pv directly on the cciss device
3) put the filesystem directly on the cciss device
Also since you have that hardware. Make sure your controller firmware is at
5.22, drives at HPG6 and backplane at 2.00
