DEC UNIX and "dump" problems

A previous SysAdmin made a "dump" script for backups on out Digital UNIX
machine.

I'm very new to Digital UNIX (Well, UNIX in general) and I can't quite
figure out what I am doing wrong.

The script, is simple:

dump -0uf /dev/nrmt0h /
dump -0uf /dev/nrmt0h /usr
dump -0uf /dev/rmt0h  /var

--------

Now, I get an error when running this script as follows:

webserv> dump.com
dump: Dumping from host [hostname deleted]
dump: Date of this level 0 dump: Wed Jun 11 16:56:42 1997 EDT
dump: Date of last level 0 dump: the start of the epoch
dump: Dumping /dev/rrz0a (/) to /dev/nrmt0h
dump: Mapping (Pass I) [regular files]
dump: Mapping (Pass II) [directories]
dump: Cannot open device file /dev/nrmt0h
dump: NEEDS ATTENTION: Do you want to retry the open?: ("yes" or "no")

---------

Everything is connected, apparently working as it should.  Now, when doing
a "file /dev/rmt0h", here is what I get:

webserv> file /dev/rmt0h
/dev/rmt0h:     character special (9/6146) SCSI #0 TZ86 tape #2 (SCSI ID #6) (SC
SI LUN #0) offline

------

The "offline" is what gets me.  I'm sure there is a simple solution to this.  But, I really need some help.  I have not done a backup in almost a month, and I'm getting worried!  Thanks...

Have you tried fiddling with the tape using the 'mt' command?
Try a 'mt -f /dev/nrmt0 rewind' or 'mt -f /dev/rmt0 status'
Also check your manual entries for 'mt' and 'tctl'.
The 'offline' output you described indicates an unloaded
(or not properly loaded) tape ...

kind regards,

Great job, that was the answer!  I actually solved the problem from a hint on a USENET post, but that was it
