To enable resources to begin providing HA services, you must perform the following operations:
Bring resource groups online
Enable the resources in their resource groups
Enable the resource monitors
Make the resource groups managed
You can perform these tasks individually or by using a single command.
After you bring a resource group online, it is configured and ready for use. If a resource or node fails, the RGM switches the resource group online on alternate nodes to maintain availability of the resource group.
