Explanation: A request was made to add or change volumes in the volume configuration. The robot number to be associated with a volume is already in use. It is associated with another volume in a robot with the same number but of another robot type.
Examine command output, debug logs, and system logs for a more detailed message on the error.
Ensure that robot numbers are unique for each physical robot in the EMM database. Delete and re-add a robot. Use a unique robot number if duplicate robot numbers are in use. Use a media management interface to identify robot numbers currently in use for all volumes in the volume configuration. If you use a command line interface, specify the correct robot type for the robot number that is associated with the request.
