correct by referring to the FRU parts list.

failure.Single failures can occur for a variety of reasons that have nothing to

do with a hardware defect, such as cosmic radiation, electrostatic discharge, or

software errors. Consider replacing an FRU only when a problem recurs. If you

suspect that an FRU is defective, clear the error logs and run the test again. If the

error does not recur, do not replace the FRU.
