Fault Information Sources

Faults are events indicating that some corrective action is required. Faults can come from three sources:

Environmental conditions

Hardware problems reported by POST

Run-time problems reported by the Solaris OS

The corrective actions indicated by faults can take three forms:

Rectify environmental conditions. For example, if a fault message reports that the temperature is too high, you might need to lower the temperature in the room where the server is located. If a fault message indicates that a power supply is receiving intermittent power, you might need to check to make sure that the power supply's power cord is fully plugged-in.

Replace a physical component. If a fault message indicates that a hardware component (such as a fan, power supply, or DIMM) has failed, replace it.

Follow the detailed instructions in the Knowledge Article supplied online at: www.sun.com/msg

Getting Knowledge Articles for Managing Faults

To manage system faults effectively, access the knowledge article database at: www.sun.com

To Get the Appropriate Knowledge Article

1. At the sc> prompt, issue the showfaults command.

sc> showfaults
ID FRU               Fault
 0 FIOBD             Host detected fault, MSGID: SUN4V-8000-8Q
 1 MB                Host detected fault, MSGID: SUN4V-8000-8Q

2. Identify the SUNW-MSG-ID string in the showfault output.

In this example, the message ID string is SUN4V-8000-8Q.

3. In your browser, go to http://www.sun.com/msg/SUN4V-8000-8Q

(Alternatively, go to http://www.sun.com/msg/ and type the SUNW-MSG-ID SUN4V-8000-8Q into the lookup window on the http://www.sun.com/msg/ web page.)

4. Read and follow the instructions in the article supplied by the www.sun.com/msg web site.

For example, the knowledge article might advise you to:

Install a specified patch and Issue the clearfaults command.

Run further diagnostics.
