Incase anyone is interested, the problem for us here was hardware. We
are still not sure of the exact issue, but there was a problem with
the library initializing it's tape drives. When the library would
attempt to auto-load a tape and label it, the tape would partially
mount physically, but then crash, with the tape leader partially wound
on to the drive reel. The library would then attempt to restart the
drive. At this point, the drive wakes up to find a tape partially
loaded, and freaks out, then immediately shuts down. All of this would
be fine, except that the cycle created tremendous noise on the scsi
chain, and basically shuts down the internal TTL bus used to monitor
the drives. The remaining drive that still operates has to deal with
CRC errors on the scsi chain. These errors freak out Networker, who
cannot understand the resulting data coming from the drive. We would
get back random volume ids from the drives, which leads to conflicts
when mounting tapes. Ugly.
We spent the past week with techs on site trying to resolve the
issues, with the final result being to replace all of our tape drives.
looks like some kind of firmware conflict.
Here was our event cycle within networker for reference. Hopefully
this will help someone else avoid the pain we went through.
First, we get this when auto-labeling a tape:

*********************************************
At this point, I can restart the cycle by going to the media database
and deleting the tape. The library will then remount the tape, and try
to label it. I always get error #1, but sometimes it labels it
properly and bypasses the chain of errors above.

Been getting the same problem here. Seems to be some problem with
labeling... at least that's what we have found. In some cases we are
able to getting things moving again by relabeling the tape with a
new barcode and trying again.
We are also getting errors at the same time about duplicate media in
the tape database, even though all IDs are unique.
here is another one in the same group...
Failed false operation: "Load"; operation device: "\\.\Tape1";
operation slots: " 2"; write enabled: "Yes"; Expected volume ID
`3509667549' for volume `079007'. The actual volume ID is

The actual volume ID is `2850665173'. 85
No idea what's going on, but it looks like it's time to call support.

Here's a weird one. I have NW 7.4 on Win2003 Enterrpise server. I'm
labeling some new tapes (via script), and I've started getting this:

Knowledgebase on Powerlink searches turn up nothing, nor does a web
search
(everything refers to Linux, and this is a Windows server).
(BTW ... love that error message - "drive status is: The tape drive
is
ready for use". Informative, that is ... :-))
I can't label using the GUI, after it fails, either. I suppose I
could try
stopping all NW services and re-starting ...
