Just for documentation purposes, I figured out how to add a second
SCSI disk (with Sean Fagan's tip). Here is the basics with an example
of adding sd2 (on my system sd0 is for NT, sd1 is freebsd, sd2 is the
2nd freebsd disk I want to add):

1. Figure out your disk parameters and make an entry in /etc/disktab.
   For me it was a st12400n.
2. Zero out the boot block of the new disk with:
   dd if=/dev/zero of=/dev/rsd2 bs=1k count=1
3. fdisk -u /dev/rsd2, and update necessary info in the partition
   you wish to use. I used partion 3 (aka /dev/sd2c).
4. disklabel -rw /dev/sd2 st12400n.
5. newfs -T st12400n /dev/rsd2c.
6. run fsck /dev/rsd2c.
7. mount disk on a valid mount point.
8. add entry to /etc/fstab for automount.

Hope this helps anyone that needs to add a second SCSI disk.

-Ron
