I had posted a few months ago about a circumstance that required reverting SEDs to their factory state in maintenance mode:
I've recently had the opportunity to try it out, and I receive a "no usable root volume found" upon execution of the disk encrypt revert_original command in maintenance mode, and the disks remain in a failed state-- subsequent "disk unfail" commands also have no effect. Although I fully expect there not to be a root volume in place and realize there's truth to the message, I would expect that I would have unfailed disks after both of the commands I used were issued.
Is there another step I'm missing here?
