It's because networker keep track of mounted volumes.
At restart, networker will restart/recreate nsrmmds and re-read
volume labels for the drives he know to be mounted.
 
Before shutting down networker, use "nsrjb -uvs <server>"
or "nsrjb -uv" issued respectively from the storage node
handling the robotic arm or from the backup server if it is
operating robot to unmount all devices.
 
This will prevent behaviour you are seeing.

Objet : [Networker] Unloading drives that are not loaded



My networker install seems to get confused about whether there is a tape
in the drive.

My situation, which I've experienced many times before, is that for one
reason or another I've had to force a shutdown of the networker daemon.
Then I manually empty the drives and restart the daemon. When it comes
back up, nwadmin doesn't show any tapes in the drives. However if I run
"nsrjb -H" or "nsrjb -I", networker tries to unload one or more of the
drives. This fails since there is no tape in the drive, but I have to
sit through 10 minutes or so of:
media info: unload retry for jukebox 'tls5433' failed - will retry
again"
media info: unload retry for jukebox 'tls5433' sleeping 30 seconds"

Is there anyway I can avoid this? Or at least is there a way I can
decrease the number of times it retries unloading a tape that is not
there?

This is Networker 7.2 on Redhat Enterprise Linux 3 server. The library
is a scsi-atached qualstar TLS5433 with 2 SAIT tape drives.


Thanks,
