Some customers may be startled by the exception messages that IBM Health Checker for z/OS issues on systems that have been running just fine the way they were. But it's really worth your time and attention to look over the exceptions and evaluate your system, because IBM® Health Checker for z/OS® reflects suggestions to improve your system's availability and avoid problems. The checks reflect generally accepted recommendations, but you will need to evaluate whether each suggestion is appropriate for your system.

One important thing to note is that an exception does not imply that there is a problem to report to IBM. Exceptions are a means for you to evaluate potential availability impacts and take action. See Evaluating check output and resolving exceptions for how to resolve check exceptions.
