How do I add another Service Group to main.cf?

You can add a Service Group using the VCS GUI, using VCS commands, or editing the main.cf file.


and then
Yes. If you need to manually startup the cluster, you have to run "hastart" on
each node. There is no command to startup VCS on every node. If you only
execute "hastart" on one node, VCS will come up, but it probably won't startup
your Service Groups. VCS has to probe each machine the Service Group can
online on, and it can't do that if VCS isn't running on one of the nodes.
