Understanding Online Diagnostics

HP-UX 11i v1 automatically installs diagnostics on all systems to provide required hardware support. The tools contained in the OnlineDiag bundle give you a complete solution to verify, troubleshoot, and monitor Itanium-based system hardware while the system is online. You can use the OnlineDiag bundle to verify, troubleshoot, and monitor many different types of Itanium-based system hardware including CPUs, memory, interface cards, and mass storage and other devices.




	CAUTION: Uninstalling the OnlineDiag bundle prevents products with dependencies on the diagnostics from functioning correctly. Not installing `OnlineDiag` removes protections against hardware failures that diagnostics provide. Without the tools, it is much harder to troubleshoot and fix problems if a hardware failure occurs. With a media install, the `OnlineDiag` bundle is installed by default with any HP-UX 11i Operating Environment.

The tools in OnlineDiag:

Protect you against some hardware failures, for example, some memory problems.
Provide EMS Hardware Monitors that notify you of hardware events that may indicate impending hardware failure.
Maintain logs that can give you critical help in determining the cause of failures.
Enable you to troubleshoot system problems.

For most computer systems, no special configuration of the diagnostics is necessary.
