Have you defined an array?
If you create the array in the adaptec BIOS you will see one large hard
disk in FreeBSD. If you do not define an array in the adaptec BIOS you
will see the individual SCSI drives as da0, da1, etc.
The GENERIC kernel has all the typical SCSI and RAID adapters compiled in,
so look at the dmesg output when you boot FreeBSD.
This message has been scanned for viruses and
dangerous content by MailScanner, and is
believed to be clean.
