Using the NMI Button to Create a Dump File
To enable CAC or your authorized Stratus service representative to diagnose problems
with your system, you might need to create a snapshot, or
dump
file, of the system’s
memory while the system is running.
One way to create a dump file is to press the NMI button on the system’s active
CPU- I ⁄ O enclosure (the enclosure whose PRIMARY LED is lit). The NMI button is the
right-most button on the front of the enclosure (Figure 3-2).
