About Online Diagnostics

HP-UX 11i v2 automatically installs diagnostics on all systems to provide required hardware support. These tools, contained in the OnlineDiag bundle, give you a complete solution to verify, troubleshoot, and monitor Itanium-based system hardware, including CPUs, memory, interface cards, 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. To ensure the reliability of your computer system, we highly recommend installing the OnlineDiag bundle with HP-UX 11i v2 (it will be installed by default with any HP-UX 11i Operating Environment).

The tools in OnlineDiag:

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