NMI functionality
An NMI crash dump enables administrators to create crash dump files when a system is hung and not responding to
traditional debugging methods.
An analysis of the crash dump log is an essential part of diagnosing reliability problems, such as hanging 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 could 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, the administrator can use the iLO Virtual NMI
feature.
