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.
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
1. 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.
2. Press and release the recessed power button at the back of the NAS controller to turn on the NAS controller.
3. 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.
4. After you are finished running the embedded system diagnostics, select Exit to exit the diagnostics and reboot the NAS controller.
Configuring the BMC Network
You can configure the baseboard management controller (BMC) local area network (LAN) port to provide KVM (keyboard, video, and
mouse) service for the FluidFS controller serial console I/O. The BMC KVM service enables the administrator or support engineer to
access the FluidFS console I/O to troubleshoot various issues over a computer network.
The FluidFS appliance hardware provides a special physical port known as the Lights-Out Management (LOM) port. This port provides a
standard TCP connection to a switch.
As of FluidFS v4, the interconnect network is an IPv6-only network. The BMC network configuration is no longer dependent on the
interconnect subnet.
You can configure a different IP address for each controller in the cluster. However, the network and default gateway are shared among
all controllers. If you check/uncheck the “Enabled” checkbox, you are enabling/disabling the BMC network on all controllers.
