         Why not setting up a resource group? After all this setup is a perfect candidate for group and adding resources afterwards is a peace of cake.


Also, you can consider either MailTo or ClusterMon are also a good option for monitoring.

it looks like you are missing the colocation constraint that ties vip 
and myservice together
