I've used promise's hardware in the past.  When I have, I defined the array 
outside FreeBSD.  When I installed FreeBSD it saw the array as just a 
single disk volume, which I partitioned in the sysinstall process.

Do you have the array already created?  What are you seeing in sysinstall 
when you go to partition the volume?
