MatrixRAID is one of those not-really-raid controllers that only
provides RAID during the boot process, and the OS has to implement RAID
in software itself.  FreeBSD has an ataraid driver to handle these
cards.  The atacontrol command lets you view status.  See the ataraid
and atacontrol manpages for more info.
