if Yes, how would I set the hardware raid? in effect I need the software raid to still see 4 hard drives?
you should be able to tell the HP raid card to use the drives as JBOD or, at worst, set up each drive as a degraded raid-1 drive by itself....then you can run linux software raid on top of that.
Last time I tried this with a HP server there was no way to run drives without having the RAID header. The RAID header tells the RAID controller to treat the disk as a JBOD, but it makes the disk slightly smaller and at a slight offset.
if neither of the above work, you could try replacing the raid card with a non-raid controller for that kind of drive - what kind of drives are they? scsi? sata? maybe the m/b has non-raid drive ports as well as the raid card.
If the ML series of HP servers is the same as the DL series then you have a RAID card that exactly fits and cables that exactly cover the distance to the drives. The easiest option is to just use the hardware RAID. Unless you are going to use ZFS or BTRFS then the HP hardware RAID is a better option. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
