I think it's pretty evident that he hasn't set up the config files.

Specifically, what you *should* do is:
1. Close to the beginning of your /etc/rc:
vinum start
Yes, this isn't quite kosher. I need to commit this to the
latest versions and -STABLE, but it won't help you if you're
running a CD version. This also assumes that you're using a
relatively new version of FreeBSD. You should try this out by
issuing this command in single-user mode. If it complains about
syntax, the version is too old. If it complains about not
finding any vinum drives, something else is wrong, and I want to
know about it.
2. In your /etc/fstab:
/dev/vinum/S /S ufs rw 2 2
(this is an example from my system; your names will differ)

The freely available version of Vinum doesn't include RAID-5. RAID-5
performance is similar to striped plexes for reading, and about
one-quarter the speed for writing.
