Installing Diagnostics - HP -UX 11i Installation And Update Manual

CAUTION

Installing Diagnostics

HP-UX 11i 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
HP 9000 system hardware, including CPUs, memory, interface cards,
mass storage and other devices.
De-installing the OnlineDiag bundle prevents products with dependencies
on the support tools from functioning correctly. This currently includes
Predictive Support and iCOD client software.
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.
The tools in OnlineDiag:
• Protect you against some hardware failures (for example, some
memory problems).
• Notify you 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 or
offline.
For most computer systems, no special configuration of the support tools
is necessary.
