About Fabric OS diagnostics
The purpose of the diagnostic subsystem is to evaluate the integrity of the system hardware.
Diagnostics are invoked in the following two ways:
Automatically during the power-on self test (POST)
Manually using Fabric OS CLI commands
The error messages generated during these test activities are sent to the serial console and
system message logs, whose output formats may differ slightly.
Use the diagHelp command to receive a list of all available diagnostic commands.
See the Fabric OS Command Reference for a complete description of each command.
