  • System for using register sets and state machines sets to communicate between storage controller and devices by using failure condition activity defined in a request
    Patent number: 5452421
    Abstract: A method and system for improved communication in a data processing system. The data processing system includes at least one host and a storage subsystem having storage subsystem devices and at least one storage subsystem controller. The storage subsystem controller includes paths coupling the storage subsystem controller to storage subsystem devices. Communication is initiated between the storage subsystem controller and a selected storage subsystem device in response to a receipt of a request for communication. The request for communication specifies a predetermined path and a specified activity in response to a failure condition. A specified activity is automatically selected in response to a failure to achieve communication utilizing the predetermined path.
