Power-on self-test
When you turn on the IBM Spectrum Virtualize™, the system board performs self-tests. During the initial tests, the hardware boot symbol is displayed.
All models perform a series of tests to check the operation of components and some of the options that have been installed when the units are first turned on. This series of tests is called the power-on self-test (POST).
Note: Some IBM Spectrum Virtualize nodes
do not have a front panel display. The node status LED is off until
booting finishes and the IBM Spectrum Virtualize software
is loaded.
If a critical failure is detected during the POST, the software is not loaded and the system error LED on the operator information panel is illuminated. If this failure occurs, use MAP 5000: Start to help isolate the cause of the failure.
