Goal


The goal of this document is to describe how to troubleshoot fan issues on the V120/210/215/240/245/250/440/445 and Netra 210/240/440 servers.


Fix


1) Determine which fan failed



Depending on System type and OS Version a failed Fan can be noticed by

(Temperature) Fault LED lit on the Front Panel or the Power Supply

Errors in /var/adm/messages

prtdiag -v output

ALOM event log (showlogs -v)

ALOM "showenvironment" command



Fans often get very noisy before they fail completely. A noisy fan can be a sign of an imminent failure.








from /var/adm/messages:



Feb 2 05:15:38 cussyb0c rmclomv: [ID 431010 kern.error] CPU_FAN @ MB.P0.F0.RS has FAILED.

Feb 2 06:15:43 cussyb0c rmclomv: [ID 431010 kern.error] CPU_FAN @ MB.P0.F0.RS has FAILED.

Feb 2 07:15:48 cussyb0c rmclomv: [ID 431010 kern.error] CPU_FAN @ MB.P0.F0.RS has FAILED.

Feb 2 08:15:53 cussyb0c rmclomv: [ID 431010 kern.error] CPU_FAN @ MB.P0.F0.RS has FAILED.









from prtdiag -v



====================== Environmental Status =======================

Fan Speeds:

---------------------------------------------

Location Sensor Status Speed

---------------------------------------------

F0 RS okay 6136 rpm

F1 RS okay 6428 rpm

F2 RS okay 6367 rpm

MB/P0/F0 RS failed 0 rpm

MB/P0/F1 RS okay 16463 rpm

MB/P1/F0 RS okay 17763 rpm

MB/P1/F1 RS okay 16463 rpm

PS0 FF_FAN okay

PS1 FF_FAN okay






2) Identify failed fan.



It is important to distinguish between an enclosure fan and a CPU fan.






======================Environmental Status ==========================

Fan Speeds:

---------------------------------------------

Location Sensor Status Speed

---------------------------------------------

F0 RS okay 13235 rpm <- enclosure fan

F1 RS okay 13235 rpm 

F2 RS okay 13500 rpm 

F3 RS okay 12272 rpm 

MB/P0/F0 RS failed 0 rpm <- CPU Fan0 for Proc 0 (left fan of processor 0)

MB/P0/F1 RS okay 16071 rpm <- CPU Fan1 for Proc 0 (right fan of processor 0) 

MB/P1/F0 RS okay 16071 rpm <- CPU Fan0 for Proc 1 (left fan of processor 1) 

MB/P1/F1 RS okay 15697 rpm <- CPU Fan1 for Proc 1 (right fan of processor 1) 

PS0 FF_FAN okay
