Solution

The fault may be determined with the output of 'prtdiag -v' command from Solaris and 'showlogs -v' command from Alom card.

# prtdiag -v

!! We can see the 'failed' status at the voltage sensors:

------------------------------------
Voltage sensors:
-----------------------------------
Location Sensor Status
-----------------------------------
PS0 P_PWR okay
PS0 FF_POK failed <<<<<<<<<<<<
PS1 P_PWR okay
PS1 FF_POK okay

!! The front service led will be lit and the power supply service led may be lit if there is power input:

--------------------------------------------------
Led State:
--------------------------------------------------------------
Location Led State Color
--------------------------------------------------------------
SYS ACT on green
SYS SERVICE on amber <<<<<<<<<<<<
SYS LOCATE off white
PS0 POK off green
PS0 STBY on green
PS0 SERVICE on amber <<<<<<<<<<<<
PS0 OK2RM off blue
PS1 POK on green
PS1 STBY on green
PS1 SERVICE off amber
PS1 OK2RM off blue

!! The FRU status will appear as 'faulty':

=========================== FRU Operational Status ===========================
---------------------------------
Fru Operational Status:
---------------------------------
Location Status
---------------------------------
PS0 faulty <<<<<<<<<<<<
PS1 okay

sc> showlogs -v

!! The 'showlogs -v' command will show the events below:

Nov 01 01:22:10 : 00070002: "PSU @ PS0 has FAILED."
Nov 01 01:07:09 : 00070002: "PSU @ PS0 has FAILED."
Nov 01 00:52:05 : 00070002: "PSU @ PS0 has FAILED."
Nov 01 00:37:04 : 00070002: "PSU @ PS0 has FAILED."
Nov 01 00:21:59 : 00070002: "PSU @ PS0 has FAILED."
Nov 01 00:06:54 : 00070002: "PSU @ PS0 has FAILED."

Additionally to the verification above, please check whether ALOM version is up to date as per "Sun Fire [TM] V440 with older ALOM firmware and intermittent power issues may cause false Power Supply failures (Doc ID 1531204.1)".

Upon all verifications, if the Power Supply is considered defective, please open a Service Request.
