-- Disassociates a node from a Chef server, and removes the node from the Chef server's managed nodes. After a node is disassociated, the node key pair is no longer valid for accessing the Chef API. For more information about how to associate a node, see 'AssociateNode' .
--
--
-- A node can can only be disassociated from a server that is in a @HEALTHY@ state. Otherwise, an @InvalidStateException@ is thrown. A @ResourceNotFoundException@ is thrown when the server does not exist. A @ValidationException@ is raised when parameters of the request are not valid.
