Memory Alert UCS C210 M2

[NAGARAJAN PARAMASIVAM]

Hi

Here I m using UCS C210 M2, got the below alert

DDR3_P1_B2_ECC: Memory sensor, non-recoverable event, Upper Non-Recoverable going high (253 > 15 error) was asserted

DDR3_P1_B1_ECC: Memory sensor, failure event, Upper Critical going high (253 > 10 error) was asserted

Can any help me to fix for this alert.

Hello,

Please open a TAC service request with CIMC tech support log bundle.

We might need to replace the memory module.

Hi Nagarajan ,

It seems like the memory DIMMs are reporting some errors on the system.

Please check on CIMC>inventory>Memory and check on DIMM status.

You can also trythe following commands from the CLI:

C210M2 /server # show dimm 

C210M2 /server # show dimm detail

C210M2 /server # show dimm-pid

C210M2 /server # show dimm-summary

C210M2 /server # exit

C210M2 /connect debug-shell

C210M2 /sensors --> Here you can check the ECC errors generated from the DIMMs.

You can also try to reset the memory in order to clear teh errors and reset the sensors on the server however as Padramas recommended you, you might want to open a TAC service request in order to have a replacement of the faulty devices.

Please check the following info for some tips:

Hope this help!

I just got this back  from the case I opened up:

"Actually these are the correctable ECC errors which does not impact the production of the server."

Please refer to the white paper to understand more on the correctable errors.

The errors ended up clearing after a day or so. but I wanted to post this out here to say that David had the right answer to this.
