This tells me that I currently have 2 active partitions, p1 & p2, on drive c1d0
This tells me that I currently have 2 active partitions, p1 & p2, on drive c0d0 (controller 0, disk 0); if a secondary controller was added or used it would therefore be c1d0 (controller 1, disk 0).
Logically my new drive should be on c1d1, & the linux device file to match should be in /dev/cciss, so:

Yup, cool, p1 is partition 1 on device c1d1

I don't want to add it to lvm to as it helps to make it more portable for me so this is all I need, your requirements may differ.
