Diagnostics Dependencies
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 solution to verify, troubleshoot, and monitor HP
servers and workstations system hardware, including CPUs, memory,
interface cards, some mass storage and other devices.
CAUTION Uninstalling the OnlineDiag bundle prevents products with dependencies
on the support tools from functioning correctly. This currently includes
iCOD client software, some auxiliary support software, and some
peripherals.
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 HP-UX 11i Operating Environment).
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
For most computer systems, no special configuration of the OnlineDiag
support tools are necessary.
