Open Stack

A node in CLEAN FAILED must be moved to MANAGEABLE state before it can be
told to "provide" (which eventually puts it back in AVAILABLE).

Try this:
`openstack baremetal node manage UUID`, then run the command with "provide"
as you did before.

The available states and their transitions are documented here:
https://docs.openstack.org/ironic/latest/contributor/states.html

I'll note that if cleaning failed, it's possible the node is misconfigured
in such a way that will cause all deployments and cleanings to fail (e.g.;
if you're using Ironic with Nova, and you attempt to provision a machine
and it errors during deploy; Nova will by default attempt to clean that
node, which may be why you see it end up in clean failed). So I strongly
suggest you look at the last_error field on the node and attempt to
determine why the failure happened before retrying.

Good luck!
