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
