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.
