The force option may be used after the install to reinitialize the Management Node. This option will regenerate keys, credential and reinititialize the site table. This option should be used, if keys or credentials become corrupt or lost.
Additional action must be taken after using the force options. ssh keys must be redistributed to the nodes, site table attributes might need to be restored, makeconservercf needs to be rerun to pick up the new credentials and conserver stoped and started, rspconfig needs to be rerun to distribute the new keys to the MM.

A new set of common ssh host keys will have been generated for the nodes. If you wish your nodes to be able to ssh to each other with out password intervention, then you should redistribute these new keys to the nodes. You can do this my reinstalling the nodes, or by xdcp or pcp /etc/xcat/hostkeys/* to the /etc/ssh directory on all nodes. If the nodes hostkeys are updated then you will need to remove their entries from the known_hosts files on the managment node before using ssh, xdsh, xdcp.
For a service node, it is probably best to re-install the service node to make sure the correct keys and credentials are picked up for node installs.
