In the ControlMode attribute, you can use these values, depending on your needs: OnOff, MonitorOnly, and OnlineOnly.
Select the OnOff value of this attribute when you want the RemoteGroup resource to manage the remote service group completely.
In case of one-to-one mapping, set the value of the AutoFailOver attribute of the remote service group to 0. This avoids unnecessary onlining or offlining of the remote service group.
Select the MonitorOnly value of this attribute when you want to monitor the state of the remote service group. When you choose the MonitorOnly attribute, the RemoteGroup agent does not have control over the remote service group and cannot bring it online nor take it offline.
The remote service group should be in an online state before you bring the RemoteGroup resource online.
Symantec recommends that the AutoFailOver attribute of the remote service group be set to 1.
Select the OnlineOnly value of this attribute when the remote service group takes a long time to come online or to go offline. When you use OnlineOnly for the ControlMode attribute, a switch or fail over of the local service group with VCSSysName set to ANY does not cause the remote service group to be taken offline and brought online.
Taking the RemoteGroup resource offline does not take the remote service group offline.
If you are choosing one-to-one mapping between the local nodes and remote nodes, then the value of the AutoFailOver attribute of the remote service group must be 0.
Note
When you set the value of ControlMode to OnlineOnly or to MonitorOnly,
the recommend value of the VCSSysName attribute of the RemoteGroup resource is ANY. If you want one-to-one mapping between the local nodes and the remote nodes, then a switch or fail over of local service group is impossible. It is important to note that in both these configurations the RemoteGroup agent does not take the remote service group offline.
