ALOM CMT Fault Management Tasks
ALOM CMT contains fault management features. To use these features, use the showfaults and clearfault commands. This chapter contains information on the following headings:
Sources of Fault Information
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 plugged-in fully.
- 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
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, it is SUN4V-8000-8Q.
3. Point your browser to http://www.sun.com/msg/SUN4V-8000-8Q
(Alternatively, point your browser 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
- Replace a faulty hardware component
