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

Abstract: 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.
