Media Manager status code: 34

Message: media ID not unique in database

Explanation: A volume entry being added to or changed in the EMM database had a media ID specified. The specified ID was a duplicate of the media ID for another volume already in the EMM database. All volumes in the EMM database must have a unique media ID.

Examine the daemon and reqlib debug logs for a more detailed message on the error.
When you add volumes to the EMM database, specify a media ID that is unique.
If you run vmphyinv, there may be two or more media in the tape library with the same media ID.
