This tells me that I currently have 2 active partitions, p1 & p2, on drive c0d0 (controller 0, disk 0); if a secondary disk is added or used it would therfore be c0d1 (controller 0, disk 1); if another SCSI controller is added or used it would therefore be c1d0 (controller 1, disk 0).

Logically my new drive should be on c0d1 (controller 0, disk 1), & the linux device file to match should be in /dev/cciss, so:

Follow the prompts to add a Linux partition, I usuallu add a primary partition using the full capacity of the drive.

Yup, cool, p1 is partition 1 on device c0d1

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.

Hint: if you need to add it into lvm look at the RAID Howto in the wiki.

If you don't see a line for /dev/cciss/c0d1p1, something went wrong.
