A computational device determines whether a generated system event in the computational device is a critical error or a non-critical error. In response to determining that the generated system event is a critical error caused by a first field-replaceable unit (FRU), the critical error is processed to initiate tasks that lead to replacement of the first FRU in the computational device to eliminate the critical error. In response to determining that the generated system event is a non-critical error caused by a second FRU, operations are performed to proactively reserve a substitute FRU to replace the second FRU to eliminate the non-critical error, in anticipation of the second FRU failing at a future time to cause another critical error.
