LEDs – Provide a quick visual notification of the status of the server and of some
■
of the FRUs.
ILOM firmware – This system 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 Operating System (Solaris OS) Predictive Self-Healing technology to keep
the system up and 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
configurable and works with ILOM to take faulty components offline if needed.
Solaris OS Predictive Self-Healing (PSH) – This technology continuously
■
monitors the health of the processor and memory, and works with ILOM to take a
faulty component offline if needed. The Predictive Self-Healing technology
enables systems to accurately predict component failures and mitigate many
serious problems before they occur.
Log files and console messages – Solaris OS log files and ILOM system event log
■
can be accessed and displayed on the device of your choice.
SunVTS software – The SunVTS software exercises the system, provides
■
hardware validation, and discloses possible faulty components with
recommendations for repair.
The LEDs, ILOM, Solaris OS PSH, and many of the log files and console messages
are integrated. For example, a fault detected by the Solaris software displays the
fault, logs it, and passes information to ILOM where it is logged. Depending on the
fault, one or more LEDs might be illuminated.

approach for using the server diagnostics to identify a faulty field-replaceable unit
(FRU). The diagnostics you use, and the order in which you use them, depend on the
nature of the problem you are troubleshooting. So you might perform some actions
and not others.
Before referring to the flowchart, perform some basic troubleshooting tasks:
Verify that the server was installed properly.
■
Visually inspect cables and power.
■
(Optional) Perform a reset of the server.
