Diagnostic Tools
The diagnostic tools range in complexity from a comprehensive validation test suite (Oracle
VTS) to a chronological event log (Oracle ILOM System Log). They include standalone
software packages, firmware-based tests, and hardware-based LED indicators.
The following table summarizes the diagnostic tools.
Diagnostic Tool Type What It Does Availability Remote Capability
Oracle ILOM SP firmware Monitors
environmental
condition and
component
functionality sensors,
generates alerts,
performs fault
isolation, and
provides remote
access.
Available in either
standby power
mode or full power
mode. It is not OS
dependent.
Designed for remote
and local access.
Preboot Menu SP firmware Enables you to
restore some of
Oracle ILOM
defaults (including
firmware) when
Oracle ILOM is not
accessible.
Available in either
standby power
mode or full power
mode. It is not OS
dependent.
Local, but remote
serial access is
possible if the
SP serial port is
connected to a
network-accessible
terminal server.
Hardware-based
LED indicators
Hardware and SP
firmware
Indicate status of
overall system
and particular
components.
Available when
system power is
available.
Local, but sensor
and indicators are
accessible from
Oracle ILOM
web interface or
command-line
interface (CLI).
Power-on Self-Test
(POST)
Host firmware Tests core
components of
system: CPUs,
memory, and
motherboard I/O
bridge integrated
circuits.
Runs on startup.
Available when the
operating system is
not running.
Local, but can be
accessed through
Oracle ILOM
Remote Console.
U-Boot SP firmware Initializes and test
aspects of the service
processor (SP)
Available in either
