Get error  "The firmware download failed because the controller cannot process the request. Failure reason: Missing certificate for DLP file.. "

SANtricity OS 11.80 introduced a Controller Firmware Cryptographic Signing change which would prevent downgrade using normal management methods from 11.80 to prior releases.

 

https://docs.netapp.com/us-en/e-series-santricity/whats-new.html#new-features-in-version-11-80

 

Additionally, there are some Disk Pool changes that may prevent the downgrade if the pool was created while the system was running 11.80 OS. If that is not true for your system, the downgrade would have to be done via fileDownload utility.

 

A KB exists for this process, but the advice would be for this to be done under direction and supervision of NetApp support.

It may be an internal-only KB with no public visibility, but still approved for use by Support.

 

Some downgrade KBs are supported and well understood so they may have public visibility (as some for downgrading earlier releases do). Others may have gotchas, so they may not be public.

You cannot downgrade from SANtricity OS 11.80 to a prior version using System Manager. I would suggest you contact NetApp support for assistance.
