Diagnostics Overview

You can use a variety of diagnostic tools, commands, and indicators to monitor and
troubleshoot a server module:
LEDs – Provide a quick visual notification of the status of the server module and
■
of some of the FRUs.
Oracle ILOM – This firmware runs on the SP. In addition to providing the
■
interface between the hardware and OS, Oracle ILOM also tracks and reports the
health of key server module components. Oracle ILOM works closely with POST
and PSH technology to keep the server module running even when there is a
faulty component. You can log in to multiple SP accounts simultaneously and
have separate Oracle ILOM shell commands executing concurrently under each
account.
