Abstract
Exemplary embodiments of the present invention disclose a method and system for monitoring a first Error Correcting Code (ECC) device for failure and replacing the first ECC device with a second ECC device if the first ECC device begins to fail or fails. In a step, an exemplary embodiment detects that a specified number of correctable errors is exceeded. In another step, an exemplary embodiment detects the occurrence of an uncorrectable error. In another step, an exemplary embodiment performs a loopback test on an ECC device if a specified number of correctable errors is exceeded or if an uncorrectable error occurs. In another step, an exemplary embodiment replaces an ECC device that fails the loopback test with an ECC device that passes a loopback test.
