Note – Unless indicated otherwise, all examples of interaction with the SP are
depicted with Oracle ILOM shell commands.
POST – POST performs diagnostics on system components upon system reset to
■
ensure the integrity of those components. POST can be configured and works with
Oracle ILOM to take faulty components offline if needed.
Oracle Solaris PSH - This technology continuously monitors the health of the
■
CPU, memory and other components, and works with Oracle ILOM to take a
faulty component offline if needed. The PSH technology enables systems to
accurately predict component failures and mitigate many serious problems before
they occur.
Log files and command interface – Provide the standard Oracle Solaris OS log
■
files and investigative commands that can be accessed and displayed on the
device of your choice.
Oracle VTS (formerly SunVTS) – An application that exercises the system,
■
provides hardware validation, and discloses possible faulty components with
recommendations for repair.
The LEDs, Oracle ILOM, PSH, and many of the log files and console messages are
integrated. For example, when the Oracle Solaris software detects a fault, it displays
the fault, logs it, and passes information to Oracle ILOM where it is logged.
Depending on the fault, one or more LEDs might also be illuminated.
The diagnostic flow chart in
for using the server module 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. Therefore, you might perform some
actions and not others.
