Troubleshooting Using HP Insight Diagnostics Online Edition
HP Insight Diagnostics Online edition is available in HP ProLiant Support Packs and from HP.COM.
The Insight Diagnostics Online edition performs various non-intrusive in-depth system and component
diagnosis while the operating system is running. The “survey feature” can identify and resolve problems
without taking the system down.
Troubleshooting Using HP Insight Diagnostics Offline Edition
Insight Diagnostics Offline edition is available in HP SmartStart by choosing “Launch server diagnostics.”
Some benefits of HP Insight Diagnostics are:
• Performs extensive in-depth system and component testing while in a controlled operating
environment.
• Survey feature enables IT administrators to track hardware and software changes in order to form a
complete and thorough auditing process for the system.
• Test results can be analyzed by IT administrators to diagnose system and component problems in
order to repair and return servers back to the production environment.
Online vs. Offline testing
Offline is the preferred testing method because it is the most accurate. When testing offline, there is minimal
interference from the operating system and address space testing is maximized because a very small Linux
kernel is used.
