Here's how I did it:

Create a big 3TB RAID5 array.

Create an 80GB virtual disk of the OS and applications (sda1)

Create as many other virtual disks as you want/need.  My raid controller
required me to make 2 as it couldn't create a disk that big. (sdb)

Install the OS as per normal onto sda1.  Should work just fine.

Manually create an LV directy onto sdb. No partitions.

Set up any LV partitions you might want.  Format and mount the drive.

I chose to use JFS which has been fast for disk checks, formatting and
overall performance seems good.
