The result of the get_introspection_status looks like this when one node fails to start and one succeeds.

[
    "Failed to run action [action_ex_id=aaf10ff1-75b8-45f8-92c2-e169325682fa, action_cls='<class 'mistral.actions.action_factory.BaremetalIntrospectionAction'>', attributes='{u'client_method_name': u'get_status'}', params='{u'uuid': u'c2f1534d-3b85-4e91-9b5b-a116a03805e7'}']\n BaremetalIntrospectionAction.get_status failed: Could not find node c2f1534d-3b85-4e91-9b5b-a116a03805e7 in cache",
