Administering a system dump on a redundant node controller including detecting a communications failure between a system controller and the redundant node controller; generating a unique identifier for the communications failure; instructing a primary node controller to provoke a system dump on the redundant node controller; provoking the system dump on the redundant node controller including suspending a processor of the redundant node controller and storing during the suspension of the processor the unique identifier for the communications failure and an instruction to execute the system dump on the redundant node controller; releasing the processor of the redundant node controller from suspension; in response to releasing the processor from suspension, identifying the unique identifier for the communications failure and the instruction to execute the system dump; and executing the system dump including associating the system dump with the unique identifier.

Administering a system dump on a redundant node controller in a computer system

Administering correlated error logs in a computer system having a system controller and one or more redundant node controllers including providing by the system controller to a redundant node controller a unique identifier for error logs; detecting by the system controller a communications failure between the system controller and the redundant node controller; in response to detecting the communications failure, generating by the system controller a system controller error log for the communications failure including the unique identifier; detecting by the redundant node controller the communications failure between the system controller and the redundant node controller; and in response to detecting the communications failure, generating by the redundant node controller a redundant node controller error log for the communications failure including the unique identifier.

Administering correlated error logs in a computer system

Recovery of a redundant node controller in a computer system including determining a loss of a heartbeat for a predefined period of time between a system controller and the redundant node controller; in response to determining the loss of the heartbeat for the predefined period of time, checking network connectivity between the system controller and the redundant node controller; if there is network connectivity between the system controller and the redundant node controller, determining whether an application on the redundant node controller is running; and if an application on the redundant node controller is running, resetting the redundant node controller through a primary node controller.

Recovery of a redundant node controller in a computer system

A method and system for providing a computer system having a plurality of logical partitions with a virtual terminal is disclosed. The computer system is coupled to an external display device through a single communications interface. The method and system include allowing the logical partitions to share the communications interface by multiplexing communications to the display device for each of the logical partitions over the communication interface. Windows are displayed on the display device for each of the logical partitions, and the communications from each of the logical partitions is then routed to the corresponding window for display on the display device.

Virtual logical partition terminal

A method and apparatus for providing a computer system having a plurality of logical partitions with a virtual operator panel is disclosed. The method and apparatus include displaying a plurality of operator panels on a single console corresponding to each of the logical partitions, and providing a buffer for each logical partition. The status codes from each of the logical partitions are then written directly to the corresponding buffer. To display the status codes of one of the logical partitions, the status code from the buffer corresponding the logical partition is read and sent to the corresponding operator panel for display.
