    P4208CP4MGHC After bios update: Pwr Unit Redund - warning

    Repete

      Hi

       

      Hoping for some help to regain the psu reduncy on our P4208CP4MGHC system.

      Everything is original and untampered.

       

       

      During bios updates last night using OFU I noticed these messages:

       

      C:\flashupdt\04>flashupdt -u flashupdt.cfg

      Power supply 1 FRU is invalid.

      Power supply 2 FRU is invalid.

      8 X 2.5 Hot Swap Backplane 1 is detected.

      Probing system for sensors and FRU device hardware...

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

       

      After succesful completion of the flash and reboot we have this in the event log:

       

      EventID:1099   Time Stamp:05/29/2015 00:44:59   SensorName:Pwr Unit Redund       Sensor Type:Power Unit                                Description:reports redundancy has been lost -Asserted

      EventID:1100   Time Stamp:05/29/2015 00:44:59   SensorName:Pwr Unit Redund       Sensor Type:Power Unit                                Description:reports redundancy has been lost, but the unit is still functioning with the minimum amount of resources needed for normal operation -Asserted

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

       

      In the BMC web console server health I see this:

       

      Pwr Unit StatusAll deassertedOK0x0000
      Pwr Unit Redundreports redundancy has been lost reports redundancy has been lost, but the unit is still functioning with the minimum amount of resources needed for normal operationWarning0x000A

       

       

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

       

      Is it something in relation to running the updates via OFU and the message stated immediately after starting the update sequece?:

      "SDR Auto-Configuration is not supported on this platform"

       

      Would rerunning the update package in EFI help the recognition of the psu´s?

       

       

      Please if anyone has suggestions on how to work this out chip in.

       

      Best Regards Peter

          I would try an AC cycle then run the FRUSDR again in EFI.

           

          Part of the flash process, the system reads the FRU (Field Replaceable Unit)  data to figure out which power supply is installed  (465w, 750W , 1200w 1600w)

          You may also want to confirm that the PMBUS wires (5 x1 plug) from the PSU is plugged into the mother board.

           

          What Power supplies are you using?

            Hi

             

             

            Thanks for response.

             

            I will be trying out your suggestion along the lines of the reset of AC cycle and then retry reading FSUDSR. .

            But since Im on a remote site I have to wait untill I have someone out there to help me out.

            ill report back as I am able to move on....

             

            Judging from the ARK it is the 750w psu´s used in this model:

            ARK | Intel® Server System P4208CP4MHGC

             

            I have done bios upgrades on the system in question before without losing its recpognition of the psu´s and system hasnt been moved around so I expect the 5 pin cable to be in place.

             

             

            Regards Peter

              Hello again

               

              It was not easy to get a set of hands out there on the remote site.....

              ut finally I managed to get the server fully AC cycled.

              Afterwards I booted it into EFI and ran the FRUSDR.....

               

              Sadly the message:

               

              Intel(R) Server Chassis P4000M Redundant Fan SKU is detected

              Power supply 1 FRU is invalid.

              Power supply 2 FRU is invalid.

              8 X 2.5 Hot Swap Backplane 1 is detected.

               

              And rest of the errors is still there........

               

              Please do you have any further suggestions?

               

              BTW I noticed themodelno. being worng in my original post. Very sorry for that.

              t is of course a P4208CP4MHGC server system and not P4208CP4MGHC

               

              Regards Peter

                Are there any other power supply sensors being reported in the EWS sensors tab?

                 

                My guess is one of the PSU is bad and hanging the PMbus so neither can be read by the BMC.

                If so all the power supply sensors should report unable to read sensor.

                 

                Being remote makes it more difficult.

                 

                You could remove 1 PSU and see if the FRU can be read on the remaining PSU , if not switch PSU again.

                 

                are you familiar with IPMItool or IPMIutil?

                Those tools can read the PSU fru data (if the bus is not hung) to see if somehow the FRU has become corrupt.
