Service Request Numbers (SRNs) Service request numbers (SRNs) are generated by the error logging facility and by thediagnostics. SRNs help you to identify the cause of a problem, the failingfield-replaceable units (FRUs), and the service actions that might be needed to solvethe problem. Displaying S...
