Why powerstore 9200T shows DIMM alerts

This is my attached file

Hi,

Thanks for your question.

It could be that first issue, Which version are you running?

Let us know if you have any additional questions.

As I said in the first post my current version is  4.0.1.2 (Release, Build 2445526, 2025-02-17 22:57:23, Retail.

Does it your mean this is just a bug and we can ignore it ?

Try swapping two dimms and see if the errors come back.

Thanks. But this issue does not show continuously and the last one is record in the events is for 2 days ago . So if we swap 2 DIMMS from the device I am not sure how many days we should wait to come back the alert .

It could resolve it as well, so a few days at least. 

@DELL-Josh Cr​ 

I will do it . But before that there is some questions: 

1 - Do I have to swap DIMM2 and DIMM3 from both nodes ?

2 - As you said this issue relates to first doc :

" https://www.dell.com/support/kbdoc/en-us/000204824/powerstore-a-healthy-dimm-module-in-an-nvme-expansion-enclosure-may-be-marked-as-missing-failed "

according to this KB it is not matter and we can ignore it . On the other hand I am using latest OS . SO do you think this is a bug or hardware error ?

Yeah the KB only applied to certain versions that you are not using, so more likely a real error, just on the node with the error you have to swap.

According to second post the figure shows Node's DIMM and does not define specific node . So we need to replace DIMM2 and DIMM3 for both nodes . Is that correct ?

Yes, do both nodes then.
