Revert SED to manufacturer's state from maintenance mode

Hello,

I've recently corrected an issue encountered on one of my user's AFF-A200 systems. The short of it is they exchanged an incorrect key with the AFF-A200 during system boot. This happened the prerequisite amount of times for the disks to be failed somewhat permanently. I was able to revert the disks to their original state by using the procedures listed here:

https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm-cmpr-930%2Fstorage__encryption__disk__revert-to-original-state.html

However, this procedure required me to insert the disks into an operational cluster in order to revert them (we were lucky enough to have one capable of reverting the disks). Is there a different procedure that can be performed to revert these disks without having a booted CDoT system? Perhaps from maintenance mode? I understand that loss of data in occurrences such as these is a by-product of exchanging the wrong key and I don't require a recovery of any data, just a factory reset of failed disks.

Hi there!

In maintenance mode, the nodeshell command "disk encrypt revert_original" can be used, as detailed at https://library.netapp.com/ecmdocs/ECMP1636022/html/GUID-76C16F4E-7497-42D3-B22B-89E94279C1BF.html

Hopefully it doesn't come up again though 🙂

Any luck on this? All the disk I have are out of a different system so all of them are locked. When I boot to maintenance mode it doesn't let me do much of anything because the drives are locked and so they show failed. when I do list disk or disk list or what ever nothing populates and none of the revert commands work.
