Hi Andreas, thank you for your answer. Maybe my description was a little fuzzy, sorry for that.
What I want is following: * if l3_ping fails on a particular node, all services should go to standby on that node (which probably works fine with on-fail="standby") * if sip service (active/active) fails on particular node, only floating ip assigned should be migrated to other node * if any of services (active/active), be it database or java container fails, both database and java container should be stopped and floating ip migrated to another node * failure of sip service should not affect database or java container and vice versa. Hope this makes it more clear, not sure that I understood how to achieve dependency tree.
