Method and apparatus for disabling defective components in a computer system
First Claim
1. A method for configuring a computer system, wherein the computer system includes a field replaceable unit comprising a plurality of components including a defective component, and wherein the field replaceable unit comprises a first field replaceable unit, and the defective component comprises a second field replaceable unit having an associated field replaceable unit identification memory configured to store error information associated with the second field replaceable unit, the method comprising:
- identifying the defective component in the computer system;
disabling at least the defective component;
dynamically reconfiguring the computer system to allow continued operation with the defective component disabled;
allowing continued operation of at least a portion of the plurality of components of the field replaceable unit other than the defective component;
generating a component map of the components in the first field replaceable unit, the component map including enable information regarding the components;
accessing the component map to disable a subset of components associated with the defective component; and
accessing the error information in the associated field replaceable unit identification memory to set a defective error bit to disable the second field replaceable unit.

Abstract
A method for configuring a computer system includes identifying a defective component in the computer system; disabling at least the defective component; and dynamically reconfiguring the computer system to allow continued operation with the defective component disabled. A computer system includes a plurality of components and a system controller. The system controller is adapted to identify a defective component from the plurality of components, disable at least the defective component, and dynamically reconfigure the computer system to allow continued operation with the defective component disabled.
