Hi-
I'm finally getting around to setting up my Exabyte EXB-8200 8mm tape
drive hooked up to an ncr0 SCSI controller on a newly installed FreeBSD
3.2 system. The tape drive IDs like this:
sa0 at ncr0 bus 0 target 3 lun 0
sa0: <EXABYTE EXB-8200 2618> Removable Sequential Access SCSI-CCS device
sa0: 3.300MB/s transfers
I've tried dump'ing & tar'ing to a couple different tapes along with
various 'mt' rewind, fsf, offline commands. Those 'mt' commands work, but
writing to the tape:
c2-sab:/backups# tar cvvf /dev/nrsa0 .

DUMP: The ENTIRE dump is aborted.
With the tape that's in there right now, I've done successful 'mt fsf 1'
and 'mt rew' commands (and each command took a while and I could hear the
tape moving), then...
c2-sab:/backups# mt -f /dev/nrsa0 rew
c2-sab:/backups# dd if=/dev/nrsa0 | od -x
dd: /dev/nrsa0: Invalid argument

It seems like I've gotta be missing something pretty basic hear, but I
can't think of what it could be. Any ideas?
