One of "those" days here, sorry.

The last RAID controller I used under FreeBSD
was a compaq 2i which showed up as /dev/ida0
and (IIRC) the RAID was /dev/idad0 (so idad0s1a,
idad0s1b, and so on).  The disks were all SCSI,
but since none of them were plugged into either
of the (more normal) SCSI controllers there were
no /dev/daN at all.
