1. Receive recovery version and short hash
A recovery coordinator will notify all subnet Node Providers of the recover image version
and associated short (6-character) hash

2. Complete Recovery
Note that the recovery can be completed from the node's remote BMC console view or from the physical console
- Reboot the machine
- During reboot, at the grub menu, press 'e' to edit the boot parameters (you must press 'e' before the 15-second timeout)
- From the GRUB edit mode screen, add the boot parameters:
recovery=1 version=ABC hash=XYZ
(replace ABC and XYZ with the version and hash provided by the recovery coordinator. Note that the hash should only be six-characters long.) - Press ctrl-X or F10 to boot
3. Wait for recovery confirmation
