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.
For more information, see the Hewlett Packard Enterprise website.
DIMM slots
DIMM slots are numbered sequentially (1 through 12) for each processor. The supported AMP modes use the
letter assignments for population guidelines.
