-- Updates engine-specific attributes on a specified server. The server enters the @MODIFYING@ state when this operation is in progress. Only one update can occur at a time. You can use this command to reset a Chef server's private key (@CHEF_PIVOTAL_KEY@ ), a Chef server's admin password (@CHEF_DELIVERY_ADMIN_PASSWORD@ ), or a Puppet server's admin password (@PUPPET_ADMIN_PASSWORD@ ).
--
--
-- This operation is asynchronous.
--
-- This operation can only be called for servers in @HEALTHY@ or @UNHEALTHY@ states. Otherwise, an @InvalidStateException@ is raised. A @ResourceNotFoundException@ is thrown when the server does not exist. A @ValidationException@ is raised when parameters of the request are not valid.
