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.

regards Martin

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the BIOS, iDrac, and raid controller to the latest versions, this will ensure the issue seen isn't caused by it being out of date.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.

Thanks for the answer!

I have 3-11-0 and 5-24-0
Doesn't the hardware error match sense key = 4?

Hi,

i mean the RPM.

Regards Martin

Hi,

yes but it should have the same speed.

Did you have any further questions?

Regards Martin

Same speed

I think this is not related to outdated software, since the system has been working stably for several years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.

Regards Martin

Thank you!
In this case, can I use any disk of the same or larger capacity, but from a different manufacturer and without dell mark?

Could you explain in more detail
The "same" speed or "not less"?
