Troubleshooting With Diagnostic Tools
38 Oracle Server X6-2 Service Manual • June 2016
Troubleshooting With Diagnostic Tools
The server and its accompanying software and firmware contain diagnostic tools and features
that can help you isolate component problems, monitor the status of a functioning system,
and exercise one or more subsystem to disclose more subtle or intermittent hardware-related
problems.
Each diagnostic tool has its own specific strength and application. Review the tools listed in
this section and determine which tool might be best to use for your situation. Once you have
determined the tool to use, you can access it locally, while at the server, or remotely.

Diagnostic Tools
The selection of diagnostic tools available for your server range in complexity from a
comprehensive validation test suite (Oracle VTS) to a chronological event log (Oracle ILOM
System Log). The selection of diagnostic tools also include standalone software packages,
firmware-based tests, and hardware-based LED indicators.
The following table summarizes the diagnostic tools that you can use when troubleshooting or
monitoring your server.
