Troubleshooting flowcharts
To effectively troubleshoot a problem, HP recommends that you start with the first flowchart in this section,
"Start diagnosis flowchart (on page
91 )," 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
92 )." 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:
• Start diagnosis flowchart (on page 91 )
• General diagnosis flowchart (on page 92 )
• Server power-on problems flowchart (on page 94 )
• POST problems flowchart (on page 97 )
• OS boot problems flowchart (on page 98 )
