Media Manager status code 153
Message: device entry is not unique in global device database
Explanation: A request was made to add a global device database record and the record specified was a duplicate of an existing record. This condition can occur if two processes simultaneously update the device configuration on the same host.
Recommended Action:
Coordinate the changes to the device configuration so that the changes come from a single source.
Investigate the global device database changes on the server (database) side by examining the daemon debug log file for a more detailed error message.
