Change barcode robot contents

Two cleaning tapes with the same name; cant you just remove one?

But only has one same . For some reason it was marked the slot 48 with that name. In this slot 48 has no tape actually.

delete the tape id on slot 48 and set barcode rules and try inventory again.

Still the same error : Barcode not unique in database ( 36 ) Media in slot 3 has the same barcode ( CLNU00 ) the average in the slot 48 . There is no change to tape yes to at or change the name on the barcode ?

How did you delete the tape? From the GUI, or command line?

After you deleted the tape, run this to make sure the ID is not in EMM anymore:

   nbemmcmd -listmedia -mediaid CLNU00

If it's there, you need to remove it by:

   nbemmcmd -deletemedia -mediaid CLNU00 -originhost <mediaserver>

Then do another inventory.

Already, Thanks to all for the answers !

I did not perform the second command for doing normal backup even with the problem and I was afraid of just delete the only cleaning tape and stop time the backup.

Marianne :
The robot actually has two cleaning tapes . Robtest showed me :

slot 3 ( addr 4098 ) contains Cartridge = yes
Source address = 4098
Barcode = CLNU00

slot 48 ( addr 4143 ) contains Cartridge = yes
Source address = 4143
Barcode = CLNU00

Thank you all for your help! 

Mariane , managed to find the address of the slot by robtest command and removed the tape directly by the robot console. Now the inventory worked without error.

Thank you!
