WORKAROUND 1
For version 9.2 and below.
Remove the tapes in question from the Media database. To remove the tapes from the media database the tapes must be “offline”. If the tapes are in the tape library, do an “open door”, this will make the tape library in an “offline” state.
Run the “Nvmeddbcheck” command. See Knowledge Base Article 79428 titled “How to use the nvmeddbcheck utility to check and compact the media database”.
If unable to repair the NetVault Media Database, then you will need to replace the Media Database, See Knowledge Base Article 81938, titled “Creating a new Media database on an existing NetVault server”
Re-scan the tapes that were deleted.
