Mapping of bare metal node states.
|
|
|
|
A node may have empty {} `properties` and `driver_info` in which case, it is
|
|
said to be "initialized" but "not available", and the state is NOSTATE.
|
|
|
|
When updating `properties`, any data will be rejected if the data fails to be
|
|
validated by the driver. Any node with non-empty `properties` is said to be
|
|
"initialized", and the state is INIT.
|
|
|
|
When the driver has received both `properties` and `driver_info`, it will check
|
|
the power status of the node and update the `power_state` accordingly. If the
|
|
driver fails to read the power state from the node, it will reject the
|
|
`driver_info` change, and the state will remain as INIT. If the power status
|
|
check succeeds, `power_state` will change to one of POWER_ON or POWER_OFF,
|
|
accordingly.
|
|
|
|
At this point, the power state may be changed via the API, a console
|
|
may be started, and a tenant may be associated.
|
|
|
|
The `power_state` for a node which fails to transition will be set to ERROR.
|
|
|
|
When `instance_uuid` is set to a non-empty / non-None value, the node is said
|
|
to be "associated" with a tenant.
|
|
|
|
An associated node can not be deleted.
|
|
|
|
The `instance_uuid` field may be unset only if the node is in POWER_OFF or
|
|
ERROR states.
