NMI Function
When the system hangs, the administrator may execute a memory dump by NMI.
Memory dump analysis is important for eliminating reliability issues such as hangs or crashes in OS, device
drivers and applications.
If crashes occur frequently, the system may hang. In this case, the recovery action for administrators will be
turning OFF/ON the system power (hard reset).
Although the information that supports root cause analysis will be erased when the system is reset, performing a
memory dump by NMI before hard reset can protect these information.
The administrators can use the iLO Virtual NMI function to force the OS a memory dump by NMI.
If the OS crashes, a STOP error will occur on the system running Microsoft Windows. In this case, Microsoft
recommends the system administrators to perform the NMI events. The hung system will respond once more by
performing the NMI event.
Describes how to use the iLO Virtual NMI function.
1. Open under Information -> Diagnostics in the left side menu of the iLO5.
2. Click the Generate NMI to System button on Non-Maskable Interrupt (NMI) Button .
