Service group dependency
- 12 years ago
You need an offline local dependency so make Both production service group parent of child acceptance service group so you have:
prod1_grp depends on accept_grp offline local
prod2_grp depends on accept_grp offline local
This means accept_grp must be offline on node 3 to be able to online or switch prod1_grp or prod2_grp to node3, so you will get a 'group dependency violation error' if you try to do this as the expectation is that if you manually switch or online prod1_grp or prod2_grp on node3, that you manually offline accept_grp first, BUT, if prod1_grp or prod2_grp fault and tries to switch to node3, then the service group dependency means VCS will automatically offlines accept_grp so that prod grp can online on node3 and in this instance if accept_grp can only run on node3, it will stay down.
