PowerEdge R620 - Multiple read errors
Good day!
I have a PowerEdge R620 server with a PERC H710P Mini (Embedded) RAID controller.
Today the system started to work slower and in the logs of the MegaRade Storeage Manager I see duplicate lines like

I checked all drives in MegaRade Storeage Manager and found that drive 6 has Media Error Count = 9 and drive 7 has Media Error Count = 410
Both of these disks (WD6001BKHG) are included in Span 1 of a RAID-10 array (there are 4 disks in total)
In the OMSA logs, I also see lines of the following form

Please tell me how to diagnose the problem and what should I do first?

Thank you. The 3-11-00 is an Unrecoverable Read Error, where the 5-24-00 is an Invalid Field in CDB. What I would suggest you do to start would be to update the BIOS, iDrac, and raid controller to the latest versions, this will ensure the issue seen isn't caused by it being out of date.
Let me know.

Hi,
yes but it should have the same speed.
Did you have any further questions?

I think this is not related to outdated software, since the system has been working stably for several years
Can you please tell me if I can temporarily disconnect the problem disk from the RAID-10 array so that the system does not work so slowly until I get a new one for replacement?
The problem disk is included in a RAID-10 array consisting of 4 disks
And what is the best way to do it?

Hi,
it would be best if you replace it when you have the new one.
Alternate Solution that you do a Backup and run it from the backup.

Hi Souldriwer,
You could check the Sense Key with this article: https://dell.to/3dSXicl
There you could see that you have a Hardware Error the faulty disk should be replaced.
Please tell me if you have further questions.
