Darkog,

Do you happen to have another R620 that we can use known good parts from to test the server? I would start by testing the controller, backplane, and drives. If unable to verify the issue as those, then I would look at the motherboard. You can also try running diagnostics to see if it spots an issue. 

Let me know what you see. 

I am afraid not.

But all the disks are listed as failed.

I find it hard to believe all drives failed from one crash.

The hardware reseat doesn't seem like a bad idea to me, I'd go ahead and include the backplane cabling, as well. I'd have to suggest exporting the RAID log, if reseating doesn't help. This will at least help to give some indication as to what the issue may be. You can view the log in a text editor. I'd search for the term "puncturing." A puncture is an event that could cause multiple drive failures, so it may be worth checking for.

Thanks.  I suspect that as well. I will try the re-seat.

I re-seated the drives and the PERC controller. Same issue.

I ran system level diagnostics and when I pull out the drives, all components seem to pass.

What I am was able to do and see.

the system consists of toshiba and seagate drives.

When I re-insert each drive, one by one, the toshiba drives report as blocked by the PERC controller software.

The seagate drives report as foreign. I am then able to import the foreign drives and volumes for the data on seagate drives. But not on Toshiba drives.

What is odd is all the drives are original Dell drives that were shipped by Dell and should not be non-certified drives.

I am attempting to downgrade the PERC controller firmware to see if the Toshiba drives will become unblocked. 

The firmware is at 21.3.5-0002, A09

The Toshiba drives have never hard their firmware updated.

Using the directions found here, would you export a TSR and upload it to https://dell.to/3lkcFvB. Afterwards would you Private Message the svc tag used to upload it. 

Thank you. 

thanks. that finally worked.

The PM feature still seems to not work.
