Subject: [Networker] Volume name/barcode mismatch

Hi, I'm new here and I didn't find this issue posted anywhere.

For more than a week, I've been having a problem with
Networker 7.3.2 on a Windows 2003 SP2 server with an attached
HP MSL 6000 LTO3 tape library.

My Networker has gotten confused. When I look at the list of
tapes in Networker, many of the volume names don't match the
tapes' barcodes. Some volume names are even repeated. For
example, a listing will list out like this:

Tape 1, volume name 2021, barcode 2132
Tape 2, volume name 2022, barcode 2022
Tape 3, volume name <unlabeled>, barcode 2132
etc.

When I inventory the tape, sometimes it corrects itself.
It'll usually say something along the line of, "expecting
tape 2021, found tape 2132." Sometimes I have to delete the
tape out of the library and relabel it, then the volume name
and barcode match again.

Sometimes when I inventory a tape that is listed correctly,
Networker will not find the tape when it looks for it.

I spent 4 hours yesterday getting most of this corrected in
Networker, then this morning when I opened networker, it had
reset all the problem volume names back.

I have tried reinventorying the entire library, tried nsrck
-L5, nsrck -m, nsrck -X, and nsrim -X. I didn't find anything
interesting in the media or message logs.

This issue appeared at approximately the same time I added an
additional tape drive to the library. When I added the drive,
I deleted out all the previous drives in Networker, then had
Networker refind the drives and configure them. It did not
indicate any problems when reconfiguring the drives.

Any ideas?

Thanks for your help.

While I didn't change any hardware, I did run into the labeling issue
just this last week.  I had just updated the server (linux) and all of
my clients to the latest jumbo patch.  I'd swapped all of my tapes out
from May and replaced them with the tape set for June.  Neither
inventory, nor relabeling corrected the label mismatches between the
physical barcode and the internal label that Networker was reporting.  I
had to do a hard reset (nsrjb -HHEv) followed by relabeling of all of my
tapes.  Since this is the first time that I've had this issue, I cannot
say that this was the "right" solution.  I've had different quirks with
v7.3.x and there are documented work arounds in the release notes for
some of them.  I will try something different next time, putting the
tape library into service mode per the tech notes, to see if I can avoid
the hard reset.
