Purpose

This article describes activity required by a System Administrator to verify whether action has to be taken on a reported loss of input power.

SunMC Event 1.3.6.1.4.1.42.2.12.2.2.1.1.8.22.1.1.5

Scope

This document is intended for System Administrators and support personnel.

Details

Auto Service Request (ASR) provides automatic processing of failure detection telemetry and SR creation for certain Oracle systems. See http://www.oracle.com/asr for more information on ASR.

Description of the event

Power supply events can be either transient or persistent. They can be generated by external changes and actions most notably by the removal of AC from a power supply.

Additional checks need to be performed in order to understand the cause of this event received by ASR.>

How to verify if there is a genuine Power Supply issue

Physical checks

Please check the power feeds for the system's PSUs

Are the power cords securely connected to all the system's PSUs?
Are the power feeds' breakers switched on?
You may need to consult your local electrician.

Software checks

Please run /usr/sbin/prtdiag -v on the Solaris command line.

Please compare the relevant parts of the output to the example of a failed PS0 provided below.

If all Fault LEDs are OFF, and all PSUs show NO_FAULT, then the fault is most likely transient and can be ignored for now.

Otherwise please collect and upload an Explorer as outlined in "What data is needed in order to troubleshoot my software or hardware problem?".
