Run Embedded System Diagnostics on a NAS Controller

The embedded system diagnostics (also known as Enhanced Pre-boot System Assessment (ePSA) diagnostics) provide a set of options for particular device groups or devices.

Prerequisites

Connect a monitor to a NAS controller VGA port and connect a keyboard to one of the NAS controller USB ports.

About this task

The embedded system diagnostics allow you to:

Run tests automatically or in an interactive mode
Repeat tests
Display or save test results
Run thorough tests to introduce additional test options to provide extra information about the failed device(s)
View status messages that inform you whether tests are completed successfully
View error messages that inform you of problems encountered during testing

If a major component or device in the system does not operate properly, running the embedded system diagnostics might indicate component failure. To run embedded system diagnostics, a NAS controller must be offline, which means it is not serving data.

The following table summarizes the embedded system diagnostics menu options.

Description of menu options
Menu	Description
Configuration	Displays the configuration and status information of all detected devices.
Results	Displays the results of all tests that are executed.
System Health	Provides the current overview of the system performance.
Event Log	Displays a time-stamped log of the results of all tests run on the system. This is displayed if at least one event description is recorded.

Steps

Press and release the recessed power button at the back of the NAS controller to shut down the NAS controller.

NOTE:Power off only the NAS controller on which you are running the embedded system diagnostics. Do not power off the remaining NAS controllers. Powering off a NAS controller disconnects client connections while their clients are being transferred to other NAS controllers. Clients will then automatically reconnect to the FluidFS cluster.
Press and release the recessed power button at the back of the NAS controller to turn on the NAS controller.
When you see the F10 = Launch Dell Embedded Diagnostics Module prompt, press F10. The ePSA Pre-boot System Assessment window is displayed, listing all devices detected in the system. The diagnostics starts executing the tests on all the detected devices.
After you are finished running the embedded system diagnostics, select Exit to exit the diagnostics and reboot the NAS controller.
