Possible Cause: If you upgrade Policy and Distribution Service to SP1 only on the primary node, the inventory files (INVENV.NCF) on the secondary nodes will not be automatically upgraded.
Action: Manually edit INVENV.NCF on all secondary nodes to add the following entries:
envset tmppath=$tmppath;$zws_install_dir\ZenWebServerRes.jar
envset tmppath=$tmppath;$zws_install_dir\xmlrpcextRes.jar
Action: Upgrade Policy and Distribution Services to ZfS SP1 on all secondary nodes.
