this is my /dev/rct/c0
crw-rw-rw-   2 root     other      4 0x070300 Jan 12 02:04 /dev/rct/c0

and my /dev/ct/c0
brw-rw-rw-   1 root     other      0 0x070300 Apr 15  1986 /dev/ct/c0

The HP-IB address of the tape drive is "3".

Be sure also that you included the "tape" driver in your kernel

From my /etc/conf/dfile
...
* Tape drivers
tape             <----------- This one
scsitape
*stape

.....

Another item: if you shutdown your system whith the tape drive on,
              the system may not find the tape drive when it will come up.
              Solution: remove the tape from the drive and put it back
                        again.
I hope this helps
