I've done some further investigating and I'm suspecting there is no "write
support" in the Adaptec AIC7XXX drivers, or at least the 2842VL.

I tried the following:  "tar cvf /dev/st0 <directory>" with my Archive 150
attached to an AHA2842VL controller. The Tape LED came on, tar went about it's
business with NO ERRORS, but the drive NEVER made a move. It was as if tar was
dumping to /dev/null.

I checked all the -current files for the AIC7XXX and ahc_isa.c drivers for any
changes since 1.2.1. There were only context changes - bus_space vs. bus_io.

Does anyone know if this is a known missing feature?

I can READ from tapes, just can't write!

Subject: Problem w/ Archive Tape & Adaptec 2842VL controller


I'm running NetBSD-1.2.1, and to be honest I haven't tried using my Archive-150
in quite awhile. I seem to be able to read a tape, however attempting to write
the tape gets me:

Nov  5 07:54:49 dakkon /netbsd: st0(ahc0:4:0): illegal request, data = 00 00 00 00 00 00
Nov  5 07:54:49 dakkon /netbsd: st0(ahc0:4:0): illegal request, data = 00 00 00 00 00 00


dakkon# tar cv /home/simmons
tar: Removing leading / from absolute path names in the archive.

home/simmons/.newsrc
tar: can't write to /dev/rst0 : Invalid argument

Any ideas?
