Make sure that you have the scsitape driver in your kernel (SAM can add
it for you).  A quick check of /etc/master indicates tha the major
number should be 54.  The minor number is similar to a 9-track drive. 
I use:

crw-rw-rw-   1 root     other     54 0x0e0102 Jul 27 15:02 /dev/dat
crw-rw-rw-   1 root     other     54 0x0e0103 Jul 27 17:14 /dev/dat.norew
