Look at the dmesg output. You'll see something similar to this:
FreeBSD 2.2-CURRENT #7: Mon Nov 6 21:08:06 MET 1995
roberto@keltia.freenix.fr:/src/src/sys/compile/KELTIA
CPU: i486DX (486-class CPU)
real memory = 33554432 (32768K bytes)
avail memory = 31363072 (30628K bytes)
Probing for devices on the ISA bus:
[...]
(ahb0:5:0): "HP HP35480A 1009" type 1 removable SCSI 2
st0(ahb0:5:0): Sequential-Access density code 0x13, drive empty
It shows that /dev/[n]rst0 is recognized.
I use the following script to backup my system on a 60mn tape (1.3 GB):
#!/sbin/tcsh
if ($uid == 0) then
date >/tmp/dump.time
dump 0ufbB /dev/nrst0 32 1300000 /
sleep 2
dump 0ufbB /dev/nrst0 32 1300000 /usr
sleep 2
dump 0ufbB /dev/nrst0 32 1300000 /usr/local
sleep 2
dump 0ufbB /dev/nrst0 32 1300000 /var
sleep 2
dump 0ufbB /dev/nrst0 32 1300000 /users
sleep 2
dump 0ufbB /dev/nrst0 32 1300000 /src
sleep 2
dump 0ufbB /dev/nrst0 32 1300000 /spare
sleep 2
dump 0ufbB /dev/nrst0 32 1300000 /work
date >>/tmp/dump.time
mt -f /dev/rst0 status >> /tmp/dump.time
else
echo Ya must be root \!\!
endif
