You said when they are loaded you get the error message... This load is automatic or manual? Given that you have duplicate in media db means you need to take corrective measures. So list the volumes with mminfo or nsrjb and removed them from media database with nsrmm command. Then label them and things should work.

Someone reported issues recently in 7.3 where tapes being removed from the library did not have the location field removed; I wonder if this may be related?

Take a look at where Networker thinks the tape is:

mminfo -q volume=name -r location

- ensure that it thinks it is in the library.

Try relabelling the tape from the command line with -vvv and see if the additional output gives us some more info:

nsrjb -vvv -S slot# -b pool

In the library are two tapes.
I had no problem that the tapes are wrong labeled.

You can also check barcode (asuming you use same label as barcode) on specific volume and then manually mount that volume - you will see what label will Networker read from the tape. If it is different from barcode then you can have HW problem, otherwise I suggest opening case on support.

As I said, this is your problem:
nsrjb: Error: Duplicate volume name `PAW530'. Select a new name or remove the original volume.

So, do nsrmm -dy PAW530 and then repeat your nsrjb command from above.

Are you matching label to barcode or do you use a template? If you remove the tape from the media database then label it as a blank tape do you still get the issue?

Yes we are matching barcode labels.
If I delete the tape from the media DB I don't have the problem.

No, that would be workaround. Solution would be to see what is causing such condition. For that you need to open a case so support can go through the history of your volumes, eventual crashes or maybe even bugs that may affect this.

?? You mean you have 2 drives or 2 pools? You must understand that you cannot have 2 volumes in same media database with same volume name or same volid. When this happens usually you get this error.

The problem is when the tape has to be reused from a backup or a clone.
It can't be the solution to manualy delete the tapes, when the tape is marked to recycle.

Thanks.

I mean 2 drives.
Yes I know that there can only be one volume with the same id.
But this tape is the same tape with the same volid.

What is yours HW configuration? Do you have library with two or more drives? It is possible that autochanger is missconfigured (devices are pointing to wrong drives) and on fast labeling it is possible to write a wrong label on tape.

Hi,
Yes we have the same Problem with the location field.

To your questions:
The mminfo brings the correct location of the tape.

The nsrjb command brings the correct messages:
nsrjb -L -j Site2_TL892_Unix -vvv -S 1 -b "Unix Backup Clone"
setting verbosity level to `3'
nsrjb: Info: Preparing to load volume `PAW530' from slot 1 into device `/dev/nst0'.

We had the same problem in 7.2. It turned out that our cleaning tape had run out of uses. This caused Networker to go crazy and cause this message to appear. When I put in a new cleaning tape and set it to 50 uses, the problem went away.
