Well, I found the answer. - Matthew and Lonnie were on the right track. I've not worked with the devfs (device file system) before. After much reading of many docs on devfs I did find a a /dev/st directory that contains the devices. If I symlink /dev/tape0 to the proper /dev/st file it then it all works.
However, the docs reference modes 0,1,2, and 3 (rewind and norewind) for tapes. What is the difference in the modes. I learned more about devfs so it was a good afternoon!
