Python 4mm Helical Scan tape drive installation

Post by Adam Caldwe » Sat, 09 Sep 1995 04:00:00

I am trying to connect a Python 4mm DAT tape backup to a Sparcstation 20
and it doesn't seem to be working.  The system sees the drive when it boots
Sep  7 10:43:01 tasmania unix: st5: <Archive Python 4mm Helical Scan>
Sep  7 10:43:01 tasmania unix: st5 at esp0: target 5 lun 0

and I've done a boot -r.  The tape ends up being pointed to by /dev/rmt/1,
but when I try issuing a command to the drive such as:
mt -f /dev/rmt/1 rewind

It always comes up with:
/dev/rmt/1: no tape loaded or drive offline

There is a tape in it, and it is powered up.  Does anyone have a clue as to
what is wrong?  I'd RTFM, but I don't have a documentation set.



1. Dump parameters for a 4mm helical scan DAT tape.

As the Subject line reads, I'm looking for the "optimal" dump
parameters for a R-Squared (vendor) 4mm helical scan DAT
tape drive. In particular, the blocking factor, dpi and size
for various tapes.

Also, what brand names would you recommend purchasing for use
in the tape drive?

Please respond by email.
