Explanation: This error occurs while trying to place media from an unexpected EMM database host into a container. All the media that are placed in a container should belong to the same EMM database host. For example, you have media from a robot that belongs to one EMM database host. Then you try to put this media into a container that already holds media from the robots that belong to a different EMM database host.
Recommended Action: Verify that you specified the correct container ID and media IDs. Read the relevant log file under the directory install_path/netbackup/logs/vault for more details. Be aware that if this directory does not already exist, a log file is not created.
