A method of operating a data processing system includes predicting values for a set of thermal sensors based on an assumed inlet air temperature and a selected configuration state. Additional values are predicted for a plurality of assumed inlet air temperatures and a plurality of configuration states. Actual thermal sensor values are then determined. A measure of the difference between each set of predicted values and the set of actual values is determined and, based thereon, a most likely configuration state is identified. The plurality of thermal sensors preferably includes an inlet air thermal sensor suitable for determining air temperature at an inlet to the system. The configuration states includes a state in which one of the thermal sensors is malfunctioning. The measure of difference is determined by squaring a difference between each actual thermal sensor values and a corresponding predicted thermal sensor value and summing the squares.
A method of operating a data processing system having a plurality of sensors, comprising:
A data processing system having a plurality of thermal sensors, comprising:
The data processing system of claim 12, wherein determining the information comprising determining a figure of merit for each of the sets of predicted values, wherein each figure of merit is determined by squaring a difference between each of the actual thermal sensor values and a corresponding predicted thermal sensor value and summing the squares.
A computer program product comprising computer executable instructions, stored on a computer readable medium, for operating a data processing system having a plurality of thermal sensors, comprising:
