Manual Node Recovery Guide

🚧🚧🚧 UNDER CONSTRUCTION 🚧🚧🚧

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 that Node Providers will use to apply the upgrade

2. Complete Recovery

Note that the recovery can be completed from the node's remote BMC console view or from the physical console

1. Reboot the machine
2. During reboot, at the grub menu, press 'e' to edit the boot parameters (you must press 'e' before the 15-second timeout)

   Do not worry if you miss the timeout. Just reboot the machine and try again.

   

3. 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.)

   🚧 Do not follow the screenshot's version and hash values! Use the version and hash values provides by the recovery coordinator! 🚧

4. Press ctrl-X or F10 to boot

3. Wait for recovery confirmation
