Abstract
Having detected an anomalous fault in a peripheral I/O slot, a processor entity may need to perform some remedial action, wherein the peripheral slot may have a fault line. First a voltage may be detected on the slot. Processor entity may set a fault if a voltage is found. A hotplug controller which may provide outputs that the processing entity may store as a fault syndrome word. The service processor or operating system, either during initial program load, or at another time, may detect that the fault could be a false fault depending on a set of predefined conditions and following the mechanism described here can then clear the fault earlier set. If an action from a previous device list is set, then there may be a clearing of the voltage fault based on determining that the action is set.
