I'm trying to understand the remotegroup concepts. Is it designed to monitor remote service group? For an example if we setup cluster 1 in on location and cluster 2 in another location, we can monitor cluster 1 service group from cluster2? And other way?

Hello,
Yes, that is the concept of remote group agent & remote group resource. When you create a remotegroup resource in cluster, you need to define the cluster name & service group name which you want to monitor.
Typically this is used when you have interdepencies in cluster, for e.g you can configure remotegroup resource in an application cluster which will monitor the database service group in a database cluster.
Here is an e.g

Thank you very much. Service group status managed by WAC ?

No WAC is not used - you configure the RemoteGroup resource with a Username and Password to communicate with the other cluster.
The RemoteGroup resource can also be used to control (online and offline) a service group as it has 3 control modes:
■ OnOffThe RemoteGroup resource brings the remote service group online
or takes it offline.When you set the VCSSysName attribute to ANY, the SysListattribute of the remote service group determines the node wherethe remote service group onlines.■ MonitorOnlyThe RemoteGroup resource only monitors the state of the remoteservice group. The RemoteGroup resource cannot online or offlinethe remote service group.Make sure that you bring the remote service group online beforeyou online the RemoteGroup resource.■ OnlineOnlyThe RemoteGroup resource only brings the remote service grouponline. The RemoteGroup resource cannot take the remote servicegroup offline.When you set the VCSSysName attribute to ANY, the SysListattribute of the remote service group determines the node wherethe remote service group onlines.

I would also recommend using a Virtual Business Service (VBS) available in 6.0 and later. Remote SGs were created to help with cross-cluster dependencies (SGs that exist in different clusters). VBS extends that to model to n-tier applications that exist on any platform VCS or AppHA supports. VBSs are much easier to configure and offer more flexibilty. See the VCS guides for details. NOTE: to configure (not RUN) a VBS, one must use VOM. VBS also allows for day to day opperations and monitoring of the "service" instead of just the point applicaiton. As most services are made up of many moving parts, it becomes important to manage to the service, not just the databvase or application.
