Abstract
An information handling system is disclosed that retires events upon device replacement. The system has several devices of one or more types and each device includes nonvolatile memory. A unique identifier, for devices of that type, is stored in the nonvolatile memory of each device. A first memory segment stores an event log. The event log has entries that identify system events. A second memory segment stores identifiers of devices that correspond to an entry of the event log. At least one of the corresponding devices is removable. The system detects the removal of the devices and, in response, removes any entries in the event log that correspond only to identifiers of one or more devices that have been removed.
