Note: You must keep in mind the difference between the logical units attached to a controller and the logical units currently assigned to a controller. Being attached means that the drives containing the logical units are physically connected to the controller. Being assigned to a controller means that the controller is currently servicing I/O to the logical units contained on the drives.
