METHOD AND APPARATUS TO ROLLBACK MEMORY DIMM LANE SPARING

A method for correcting improper repair actions in a computer system includes assigning a first algorithm identifier to a first algorithm and storing the first algorithm identifier and a first input to the first algorithm. The method includes executing the first algorithm with the first input and storing one or more results of the first algorithm, where the one or more results includes a repair action. The method includes determining that the repair action is faulty and storing the algorithm identifier for the first algorithm in a blacklist. The method also includes assigning a second algorithm identifier to a second algorithm and storing the second algorithm identifier and a second input to the second algorithm. The method includes executing the second algorithm with the second input, where the second algorithm corrects the faulty repair action caused by the first algorithm, and storing a result of the second algorithm.
