[lug] Raid on a Compaq DL380

[Erick Bodine]

Thanks Peter, this is at least a start.  I had begun a search on the
Compaq site and wasn't getting very far.

That device node is specific to the Compaq RAID controller.

I've never used that particular controller, but it makes sense to
configure a single disk on a RAID controller as a RAID 0 to allow for
future expansion.

I found this:

Looks like you have to do some device-specific stuff for this
controller. 
Not sure if you need a special fdisk or just a special device.
