ABSTRACT:
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.
