Troubleshooting Details

• A System Board, I/O Board, Repeater, or System Controller reports unusually high or low temperature warnings or messages.
• Fan Tray(s) may be marked Failed in showenvironment output from the System Controller.
• A domain may be unable to be powered on and booted or it could be completely unaffected by the issues.
• The System Controller should be accessible (able to login).

The steps will provide instructions or a link to a document, for validating the step and taking corrective action  as necessary. The steps are ordered in the most appropriate sequence to isolate the issue and identify the proper resolution. Please do not skip a step.

1. Verify external power is present for the system.

• Confirm systems lights are on, fans are spinning, and SC is responsive or you are able to login to the SC or domain.
• See <Document 1010053.1> Troubleshooting Complete system Power Outages on Sun Fire [TM] Serengeti or LightWeight8 Systems if the system has no power.

2.  Verify that all Fan Trays are active and ok (not marked FAILED in showenvironment).

• Confirm the status as shown in <Document 1011930.1>  Sun Fire[TM] (3800-6800) System Controller Application (ScApp) How To's.
• If there is a failed Fan Tray then please follow the instructions detailed in <Document 1008393.1>Troubleshooting Cooling Fan Failures on Sun Fire [TM] Serengeti or LightWeight8 Systems starting after Step 3 of that document.

3.  Verify that a single System Board, I/O Board, Repeater, or System Controller's temperature is high as shown in showenvironment output.

• Confirm the status as shown in <Document 1011930.1>  Sun Fire[TM] (3800-6800) System Controller Application (ScApp) How To's.

4.   Verify the errors persist if the component is replaced.

• Reference the appropriate System Service Manual for complete instructions on FRU replacement and procedures:
• Sun Fire 6800/4810/4800/3800 Systems Service Manual
• Sun Fire[TM] V1280/Netra[TM] 1280 Systems Service Manual
• Sun Fire[TM] E2900 System Service Manual
• Sun Fire[TM] E4900/E6900 Systems Service Manual
• Netra[TM] 1290 System Service Manual

5.   Confirm the errors persist on the same component when the other SC is main.

• If the errors cease utilizing the new SC, then the former SC is suspect.
• SC failover reference: <Document 1003245.1> Sun Fire[TM] 3800-6900: System Controller failover functionality

6.   Collect the following data and collaborate with the next level of support .

• It is preferred that Explorer with the appropriate scextended or 1280extended option as detailed in <Document 1018748.1> How to Run Sun[TM] Explorer and Forward the Data to a Sun Engineer
• If Explorer data can not be collected for whatever reason see <Document 1003529.1>   Procedure to manually collect Sun Fire[TM] Midrange System Controller level failure data
