ABSTRACT:
Disclosed is a computer implemented method, data processing system, and apparatus to respond to detection of a hardware interface error on a system bus, for example, during a concurrent maintenance operation. The service processor may receive an error on the system bus. The error identifies at least one field replaceable unit and may inhibit the suppression of clock signal to the field replaceable unit. The service processor adds an identifier of the field replaceable unit to an eligible Field Replaceable Unit (FRU) list. The service processor recursively adds at least one field replaceable unit that the field replaceable unit depends upon. The service processor suppresses the clock signal to the field replaceable unit. The service processor inhibits tagging the field replaceable unit as unusable for next initial program load.
