hi, responsilibity by ClusterIP is expressed in terms os hash values. Hash values are deducted from the # of the clone in the custer. So if one agent is the first clone it will get hash 1, ... if one node dies this agent is started on an other node, which means that the it also gets the responsibility for the second hash. for more info see my articles in German Linuxmagazin last year. links to the articles are on www.multinet.de -> artikel und veröffentlichungen. see also www.linux-ha.org/ClusterIP beware that more than one ressource can run one one node! You are welcome for more questions.
