The following new resource group property should be added to the rg_properties(5) man page.
Auto_start_on_new_cluster
This property controls whether the Resource Group Manager starts the resource group automatically when a new cluster is forming.
The default is TRUE. If set to TRUE, the Resource Group Manager attempts to start the resource group automatically to achieve Desired_primaries when all nodes of the cluster are simultaneously rebooted. If set to FALSE, the Resource Group does not start automatically when the cluster is rebooted.
