Installing Online Diagnostics

HP-UX 11i v1.6 automatically installs support tools 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 support tools from functioning correctly. Not installing the `OnlineDiag` bundle also removes protections against hardware failures that the support tools provide. Without these tools, you will find it much harder to troubleshoot and fix the problem if a hardware failure occurs. To ensure the reliability of your computer system, we highly recommend installing the `OnlineDiag` bundle with HP-UX 11i (it will be installed by default with any 11i Operating Environment).

The tools in OnlineDiag:

Protect you against some hardware failures (for example, some memory problems)
Notify you of hardware events that may indicate impending failure
Maintain logs that can give you critical help in determining the cause of failures
Let you troubleshoot system problems with the system online

For most computer systems, no special configuration of the support tools are necessary.
