Power Supply Redundancy Lost with no corresponding PSU Issue

Question

Looking for troubleshooting advise for this issue being alerted as Critical in OME.

I am receiving solely the Power Supply redundancy is lost alert without any sort of issues with either of the redundant power supplies. There isn't anything correlating in the hardware or event logs concerning power or the PSUs. However, I am seeing a "The memory module 1 temperature is greater than the upper warning threshold." at the same time frame (only thing consistently mapping up over past week. The redundancy is lost for 8-10 hours and then comes back for 16 or so hours over past few weeks.

All firmware and drivers are updated to current Dell pack. that seemed to address it for a day or two...

Before I send a field person to look at it, any ideas what this might be???

What model server is this on? Do the same errors show up in the server administrator logs, drac logs or on the front display on the server?

DELL-Jeff M · Answer

If the Hardware Logs and Alert Logs disagree in OME, then make sure your OMSA and BMC/ESM/DRAC firmwares are up to date.  Odd error combinations like this are usually caused by out of sync OMSA and embedded server management because they aren't validated to work with each other.

Sorry if I was unclear. The logs all have the same error solo error. The issues is that it is JUST a redundancy lost alarm and absolutely no issues in any logs with the associated power supplies.

OME, OMSA (on machine), iDRAC, ESM all show the Redundancy Lost alarm. (don't want to truck the 20 minutes to check the front display, hence remote management tools :) )

The only other alarm that matches up in any of the logs is that memory high temp warning (and it does match up)

It is a DELL PowerEdge R710 with Server 2003 R2. I have used OME to fully update the machine to current packs.

So how is there a redundancy lost when both PSU are working perfectly fine? And a consistent and recurring redundancy lost?

Lukeal · Answer

Nope. Not is OME or OMSA.

If you look under the FRU tab in OMSA what does it show for the model and firmware version of the power supplies? Some of them have a firmware update that is not done with the normal updates.

Does it have a part number for the power supply?

Lukeal · Answer

The power supply lists the version as 08.05.00

DELL-Josh Cr · Answer

Here is the update for the 570W power supply, if it is a flextronics branded one this update may help, if it is a different brand it wont update: Flextronics 570W (VPR1M) Power Supply Firmware Version 1.32, Released 1/12/12, Optional

You may be able to get the part number under the FRU section seperate from the power supply section on the left pane in OMSA.

Lukeal · Answer

The power supplies are not listed on the FRU on OMSA or OME. And that wasn't the right package for the system. :(

Can you run a DSET report http://downloads.dell.com/FOLDER01378061M/1/Dell_DSET_3.4.0.271.exe on the server and send it to me? Josha_craig@dell.com

It sounds like it might be a motherboard issue with the odd reporting and the memory temperature errors.

Lukeal · Answer

Um yeah, exactly what I originally said. Redundancy lost with no issue for Power supplies :) Yes, the memory high temp happens almost every time. Yes it is under warranty

DELL-Josh Cr · Answer

In that screenshot it shows redundancy lost but each of the power supplies show healthy. Do the memory temperatures happen repeatedly as well when the power supply redundancy is lost? Is the system under warranty?

Lukeal · Answer

Doing that now. I also checked the box that says 'upload automatically to dell site' not sure what that will do :)

Did you ever find a solution to this? I just experienced the same issue on an R620. Power supply redundancy lost and at the same a time, a memory temp alarm. However, the power supplies show up as normal/green in open manage.

SubnetKing · Answer

The error is caused by a firmware bug in the 8.05 package.

To resolve the issue you will need to apply a power supply firmware update.
