NMI functionality
An NMI crash dump enables administrators 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 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 do any of
the following:
• Short the NMI jumper pins
• Press the NMI switch
• Use the iLO Virtual NMI feature
For additional information, see the whitepaper on the HP website
