Diagnostics
HP-UX 11i v2 provides a complete set of tools for verifying, troubleshooting, and
monitoring HP system hardware, including CPUs, memory, interface cards, and mass
storage devices. Diagnostics (also known as Support Tools) in HP-UX 11i v2 include the
Offline Diagnostic Environment (ODE) and Online Diagnostics (EMS Hardware
Monitors and Support Tools Manager).
The Offline Diagnostic Environment is delivered on the Offline Diagnostics & Utilities
CD. Online Diagnostics are delivered in the Operating Environments.
This section covers the following topics:
• “Offline Diagnostic Environment” on page 60
• “Online Diagnostics” on page 62
Offline Diagnostic Environment
The Offline Diagnostics Environment (ODE) is an offline support tools platform that
enables users to troubleshoot a system that is running without an operating system or
cannot be tested using the online tools. The ODE is also useful for some types of testing
in which it is not desirable to have to boot the system first.
The Itanium-based ODE includes offline diagnostics and utilities for all current
Itanium-based hardware systems, and is delivered separately on the Offline Diagnostics
& Utilities CD.
