Diagnostics Overview

You can use a variety of diagnostic tools, commands, and indicators to monitor and
troubleshoot a server:
LEDs – Provide a quick visual notification of the status of the server and of some
■
of the field-replaceable units (FRUs).
Oracle ILOM – This firmware runs on the service processor. In addition to
■
providing the interface between the hardware and OS, ILOM also tracks and
reports the health of key server components. ILOM works closely with POST and
Solaris Predictive Self-Healing technology to keep the system running even when
there is a faulty component.
Power-on self-test (POST) – POST performs diagnostics on system components
■
upon system reset to ensure the integrity of those components. POST is
configureable and works with ILOM to take faulty components offline if needed.
