This includes how the problem is detected, and what are the possible causes of the problem.
With the problem known, the effect of the problem is recorded with all known results from the
problem. Once the problem is quantified, the solution is applied. Solutions are found either in
this chapter, or through customer support. If no solution is found in this chapter, contact
Customer Support.
