It could be correct if you haven't set up your RAID card correctly. Is 
it a hardware or software controlled RAID card. If it's hardware 
controlled, you have to set up your RAID configuration in the card so 
FreeBSD recognizes it as 1 disk. If it's software controlled, cou can 
use something like ccd or vinum.
See this articles for more info on vinum:
http://www.freebsd.org/doc/en_US.ISO8859-1/articles/vinum/index.html
Or the RAID section from the trusty handbook:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/raid.html

Good Luck,
Jason
