The availability of the diagnostic tools depends on the state of the server. These topics describe which tools are available, when they are available, and how to access them.
These tools are available to perform diagnostics:
Status LEDs – Indicate the condition or state of the chassis and components. See Interpreting LEDs.
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.
Predictive Self-Healing (PSH) – PSH continuously monitors the health of the CPU, memory and other components, and works with Oracle ILOM and Oracle Solaris to take a faulty component offline if needed. PSH enables systems to accurately predict component failures and mitigate many serious problems before they occur.
Oracle ILOM – The Oracle ILOM firmware runs on the service processor. In addition to providing the interface between the hardware and OS, Oracle ILOM also tracks and reports the health of key server components. Oracle ILOM works closely with PSH to keep the system running, even when there is a faulty component.
Oracle VTS – This application exercises the system, provides hardware validation, and discloses possible faulty components with recommendations for repair. Refer to the Oracle VTS documentation for more information at:
