NMI functionality
An NMI crash dump enables you to create crash dump files when a system is hung and not responding to
traditional debug mechanisms.
Crash dump log analysis is an essential part of diagnosing reliability problems such as hangs in operating
systems, device drivers, and applications. Many crashes freeze a system, and the only available action for
administrators is to cycle the system power. Resetting the system erases any information that might support
problem analysis, but the NMI feature preserves that information by performing a memory dump before a
hard reset.
To force the OS to invoke the NMI handler and generate a crash dump log, do either of the following:
•
Short the NMI header pins.
•
Use the iLO Virtual NMI feature.
