I think a reasonable summary is that although the documentation says it's not supported, if you're up to date with the firmware you might get away with it, but no-one in their right mind would risk it. In theory you can bodge the buttons inside to offline the board and /usr/platform/SUNW,Sun-Fire-V890/lib/sf880drd should spot the fact and migrate everything off there to allow you to pull the board. If you've made up with your favorite deity. Anyway, scheduled downtime it is. Thanks to Scott Lawson, Dean Ross-Smith, JayJay Florendo, Tim Bradshaw, and Joe Fletcher. Your input is really appreciated.
