Are they just showing up as failed right now? You can unfail them, using disk unfail (that is a "priv set diag" mode command). That should do it, but if not, you might have to remove them from the failed disk registry. For that you should reboot, and hit ^c to dump you into the 1-5 menu. Choose option 5 for maintenance mode, and from there, run the command 'raid_config info deletefdr' and choose those disks to fail. You'll see numbers corresponding to known failed disks, this system has seen, just choose the disks you want back.
I don't know of a way to 'low level format' a disk in ontap. There is 'disk sanitize', but I'm not sure that's the same thing enough for you. The above actions, at least, will bring the disks back to you.

Greetings Toaster fans,
We powered down four F840s last week, reconfigured them with the newest drives we had (it's a long story), and upon reboot, at least three of the drives started experiencing random failures. These failures are enough that ONTAP gripes and marks them as "failed", but I suspect that a low-level format should bring things back to a sane state.
Can ONTAP low-level format a 520B/sector disk, or do I need to find something else to do that? If the latter, does anyone have an idea as to what I can use?
Many thanks!
