Abstract: A method and apparatus for configuring a mass storage system, in which an array of disk storage devices connect to a storage controller and a plurality of host computers also connect to the storage controller, provide the capability, using a convenient graphical user interface at the host computer, for enabling the user at the host computer to determine the status and configuration of the system. The user can also, using the graphical user interface, modify the system status or configuration. Various graphical user interface techniques can be used including "click and drag" and other user friendly presentations and operations. The system uses either proprietary communications channels between disk drive controller and host computer, or modifies standard protocols in order to enable the necessary communications to occur.
