A node can be added as a Managed Node in which case the controller can provide resources for Pod's scheduled on the node or it can be added as a un managed Node in which case controller doesn't do any operations on the Node or any Pods scheduled on the Node. A node can be toggled from Un-Managed to Managed and vice-versa in which case the Node Manager updates it's status accordingly
