EF570(DE6000F) : failed 2drives in RAID6

[SoichiFromLenovo]

If a heavy load with an access size of 4KB (Queue=128/Random=100%/Write=100%) is applied, 2 drives in RAID 6 will fail.
This will definitely happen and failed drive cannot be reused.
Firmware:08.62.00.02.001

NVSRAM:N5700-862870-D0

*8.53.x does not have this failure.

who knows?

[SpindleNinja]

can you clarify your question?  or are you stating a bug that needs to be looked at? 

[andris]

It sounds like you should open a technical case with NetApp so that it can be investigated.

Hello Soichi,

Were you able to open a support case for this?
We will need to look at a full support bundle and trace buffers collection after the failure to understand why the drives are failing during your IO test.

[SoichiFromLenovo]

Thanx!! yes.

[SoichiFromLenovo]

yes, i opend support request now.
I checked to see if anyone knew about this obstacle.
Thanxx!!

Hi NetApp_RZ

Thanxx for your reply.
I opened support case via IBM Support (IBM MCC) now.
This product is sold by Lenovo and must go through IBM Support.
I will add it within the range that can be disclosed at a later date.
Thanxx!

Soichi,

Thanks for the update.
I was looking in our system for a possible case surrounding the issue as I am curious too about what the drives are doing to hit fail criteria during that IO test.
Could be timeouts or aborts but could be other things too.
Either way, IBM/Lenovo does have escalation paths into NetApp should the need arise to get a deeper look at the issue so will keep an eye on this thread.

Thanks  🙂
