NMI functionality
An NMI crash dump creates a crash dump log before resetting a system which is not responding.
Crash dump log analysis is an essential part of diagnosing reliability problems, such as failures of
operating systems, device drivers, and applications. Many crashes freeze a system, and the only
available action for administrators is to restart the system. Resetting the system erases any information
which could support problem analysis, but the NMI feature preserves that information by performing a
memory dump before a system reset.
To force the system to invoke the NMI handler and generate a crash dump log, do one of the following:
• Use the iLO Virtual NMI feature.
• Short the NMI header ("System board components" on page 85).
