/dev/rmt/0: No such device or address

I get this when I do a "mt -f /dev/rmt/0 rewind"

This is on a Solaris 7 system.
I tried

devfsadm -c tape

and

drvconfig ; tape

and both didn't work.

Help please.......

What is listed in /dev/rmt ? If you have a tape drive on the server, and you run the commands you did or do a reboot with reconfigure, it will see the tape drive and give it a new number...try the last/largest number versus 0.

I tried 0-9 but still nothing. Here is the /dev/rmt........

0 0hn 0u 1cn 1mb 2bn 2lb 2ubn 3hb 3mn 4cb 4ln
0b 0l 0ub 1h 1mbn 2c 2lbn 2un 3hbn 3n 4cbn 4m
0bn 0lb 0ubn 1hb 1mn 2cb 2ln 3 3hn 3u 4cn 4mb

Check the connections from the server to the tape - more than likely you should be using /dev/rmt/4. You might want to just remove /dev/rmt/* and then try getting it to see the tape drive again (making it /dev/rmt/0 ). Are you sure it's a good tape drive? Got the scsi terminator on or is it self terminating?

#rm /dev/rmt/*
#drvconfig -i st
#tapes

Then

#mt status (should find /dev/rmt/0)
