    摘要: A method and data processing system for isolating a faulty component in a computer. A first microcontroller detects a fault in a component of a computer. Responsive to detecting the fault, the first microcontroller sets a first fault record for the component to pending fault, sets a second fault record for the first microcontroller to pending fault, and fails over to a second microcontroller. If the second microcontroller detects the fault in the component of the computer, then the first fault record for the component is set to permanent fault, and the second fault record for the first microcontroller is cleared. If the second microcontroller determines the component of the computer does not have the fault, then the first fault record for the component is cleared, and the second fault record for the first microcontroller is set to permanent fault.
