Thanks guys, I've gotten alot of responces from various places, as well as from NetApp tech support.
Basically, I need to do:
filer> rc_toggle_basic
Now notice the * in the prompt, it means we're in super duper mode. Now we clean the disk header:
filer*> disk_erase_label <disk>
Which does what I need. I then did a rc_toggle_basic again to get back to normal mode, then I did a double disk swap to remove and re-insert the problem disk.
It came back properly as a spare disk.
There are still two issues with DataOnTap 5.2.1 though:
1. It allows two different volumes with the same name to exist on the system.
2. When you remove the last disk in a volume, it keeps the volume around. I think this is somewhat related to #1 though.
