scsi tapes

[Steven Gutfreund]

Can anyone out there explain how SUN OS 4.0.3 handles scsi tapes?

I have a WANGTEK 5500 (150 Meg) tape drive on by SS1.

1. MT says my tape is a QIC-150 : What do the QIC numbers REALLY mean.
2. Sun admin guide says if I call it /dev/rst0 I write in QIC-11 format
   and /dev/rst8 in QIC-24 format. Really? what do the device numbers mean
   and why does scsi-probe say there are 8 units there?
3. What bpi should I use in dump?
4. I have a DAT at scsi address 5, what /rst? should it have, and what
   should I tell dump.

Basically, I'm asking some generous person to put a short tutorial on scsi
tapes out on the net.
