at the same time 4 disk failed md3220i no response at start-of-day

Hello dr.kiev,  I have not other unit to test

Do you have a chance to remove those failed ssds and test them individually on another station?

I've had this happen before on a SAN where three drives failed but the disks weren't actually bad.  It was a software bug, and support was able to recreate the raid array and come back up.

Do you have current support from Dell?  If so definitely log a support ticket.

Hello Metzge,

Unit warranty expired on 2018 and Dell did'nt allow us to buy an extension.

Hello everyone, 

Same thing happened. This morning 4 SSD became unresponsive all of a sudden.

Have you solved the issue in any way ?

Thanks

Hello geneda,

What is your current version of controller firmware on your MD?  What is your current version of hdd/ ssd firmware? Did you have a power outage recently? 

Hello, 

No power outage. 

Current Package Version: 08.20.16.60
Current NVSRAM Version: N26X0-820890-008

They are 800GB SSD Model SXKLTK, SanDisk LT0800MO firmware version D40Z

Thanks,

Dan

Hello geneda,

As sculljam_ posted a link to the KB that explains more about the issue & how to resolve it.

Hello, 

Thank you for you answers!

The article states that "Upgrading the drive firmware to version D417 (or newer) prior to 40,000 power-on hours should address this issue." and "If the drive has already failed due to this issue or additional help is required, please  contact support."

On the PowerVault I can't upgrade the firmware since the disks are unavailable and won't show in MDSM Disk Firwmare upgrade window.

I've tried installing a disk on a PE R720 and upgrading it with DSU, but the app won't upgrade it: "No Applicable Updates Available".

Command "dsu --inventory" shows "( Version : )" where the disk is located, although iDrac identifies the product as LT0800MO with firware revision D40Z.

Thank you!

Hello geneda,

In your case since the drive is not able to be upgraded you would need to replace the drives.  If your system still has a service contract, then you can call into support and we can replace them.
