Replacement Disk broken - how to dowgrade firmware?

GarryO

Hi - any help appreciated.  I replaced a disk on my 3220 (Ontap 9.1P14) with an identical disk.  The only difference I can see is the firmware is NA02 while all the other disks are NA01.  The disk reports init failed and broken - I did try unfail and also "storage disk firmware  revert -disk..disk #" but still not working and showing same firmware on re plugging in.  I have tried several disks from the replacements and all behave the same.

 

Any ideas please?  Garry

Why not upgraded the rest..?

Hi

 

I would prefer to do that later maybe when I have a spare added back into the aggregate - so downgrade process would be great

Thanks

I don’t follow.   Why?  
Having the latest DQP and firmware is best practice.  It’s all a non-disruptive procedure too.     

 

Are you in a degraded state currently? I don't understand. I agree with Spindle, please upgrade firmware and DQP.
