Hi Brandon, 

I recently dealt with the same controller, with a 3TB array.  My
solution is tons easier than dealing with gpt or breaking it up.  So
long as you don't need to boot from the raid, and you just want it as
one big disk, forget partitioning it.  newfs the device directly, and
mount it directly.  

drue at leopard:~$ df -h
...
/dev/da0       2.6T    182G    2.3T     7%    /d

I just did a newfs on /dev/da0 and mounted it.  Works /great/.  No fuss.
