Note – Unless indicated otherwise, all examples of interaction with the SP are
depicted with Oracle ILOM shell commands.
POST – Performs diagnostics on server module components upon reset to ensure
■
the integrity of those components. POST can be configured and works with Oracle
ILOM to take faulty components offline if needed.
PSH – This Oracle Solaris OS 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 server modules 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 server
■
module, 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 OS 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 flowchart in
for using the server module diagnostics to identify a faulty 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.
