attached mail follows:
In brief, my problem was that I somehow lost the tape drive
drivers (probably due to me plugging things into the scsi
controllers differently when I set my system back up) and
was getting a message like "device not found" when I'd try
to ufsdump or mt to it. The "reboot -- -r" (and the many
alternative ways to do that...) failed to correctly create
the drivers for me and "drvconfig" and "tapes" wasn't doing
the trick either.
The first and best answer came from Glenn Satchell who wrote...
The way to recreate tape devices is:
rm /dev/rmt/*
drvconfig
tapes
I did these three steps in this order and that fixed it!
Apparently you have to delete ALL of the drivers in /dev/rmt/
in order for drvconfig or boot -r to work at all!
Another suggestion from Jason Boerner was to try "boot -rs".
I don't know what that does. I was going to try that 2nd
but Glenn's trick worked so I couldn't test Jason's.
Thanks also to Alan Hill and Matthew Stier for taking the time
to reply.
