If you plan to reinstall the Solaris Container Manager 1.1 software on the server layer, be sure to save the data when uninstalling. Similarly, if you run setup again on the server layer, be sure to answer No when asked if you want to re-create the database. Otherwise, agent hosts previously discovered might be missing from the database if the data was not saved and you then reinstall or set up again on the server layer.
Workaround: If hosts are missing after you reinstall or rerun setup, restart the Sun Management Center agent on the hosts by doing the following procedure:
Log in to agent system.
% su -
Stop the Sun Management Center agent by typing:
# /opt/SUNWsymon/sbin/es-stop -a
Start the Sun Management Center agent by typing:
# /opt/SUNWsymon/sbin/es-start -a
