Troubleshooting flowcharts

To effectively troubleshoot a problem, HP recommends that you start with the first flowchart in this section,
"Start diagnosis flowchart (on page 25)," and follow the appropriate diagnostic path. If the other flowcharts
do not provide a troubleshooting solution, follow the diagnostic steps in "General diagnosis flowchart (on
page 25)." The General diagnosis flowchart is a generic troubleshooting process to be used when the
problem is not server-specific or is not easily categorized into the other flowcharts.
The available flowcharts include:
•
