OK...here's a question for everyone.

I have come into a NBU 6.5.3 environment as a new backup admin.  For some 
unknown reason they had no barcode rules defined, so all of the 8-character 
barcodes are getting the last 6 characters for the media database.  Hence a 
barcode that has AP1000L3 is turned into a media code of 1000L3.  When you do a 
vmquery -m 1000L3, it will show the full barcode, but that's not how it is 
indexed in the media database.
 
So, the problem is if you change the barcode rules now, you will basically have 
an issue with tapes create prior to changing the rules.  So, if you send off 
tape 1000L3 and change the barcode rules and then bring it back it will now be 
read as AP1000 and the media database will think it is a new (Scratch) tape 
instead of the tape with whatever data is associated with 1000L3.  See the 
problem?  
 
Is there any way to basically change the existing media id's to the proper ones 
prior to implementing a proper set of barcode rules?  Or is that a lost cause?  
The vmchange command doesn't seem to be able to do this.

Has anyone run into this situation before?

thanks.
