Using the NMI Button

To enable your authorized Stratus service representative to diagnose problems with your system, you might need to create a dump file of the system's memory while the system is running.

One way to create a dump file is to press and hold the NMIClosed A process, initiated when the system is not responding, where the system controller tries to restart the system by saving the contents of memory to a dump file, and then restarting the operating system. The interrupts are intended to keep all CPUs synchronized while the system controller attempts to resolve the problem. button (see Figure 3) on the active compute moduleClosed A customer-replaceable unit (CRU) located at the front of the ztC Endurance system. It is equipped with processors, RDIMMs, BIOS, BMC, fans, and other technology to boot and run the ztC Endurance system. Each system contains two compute modules. for four to eight seconds.

Notice: Pressing the NMI button stops any running applications. Do not perform a dump operation if you want any applications to continue operating. Instead, schedule downtime for this procedure.

You may need to press and hold the NMI button more than once to generate the dump signal. However, do not press the NMI button while a dump is in progress. This may result in an unusable dump.

If the dump signal is generated on VMware vSphere-based systems, a purple screen appears on the monitor, displaying the number of the software components (for example, 3/9, indicating that it is dumping the contents associated with the 3rd of 9 components.) If the purple screen does not appear, the dump signal was not generated.
