156 VCS infrastructure and support agents RemoteGroup agent Table 7-15 RemoteGroup agent optional attributes (continued) Optional Attribute ReturnIntOffline Description Select one of the following values for RemoteGroup to return IntentionalOffline: ■ ■ ■ RemotePartial.Indicates that the RemoteGroup resource returns an IntentionalOffline if the remote service group is in an ONLINE|PARTIAL state. RemoteOffline.Indicates that the RemoteGroup resource returns an IntentionalOffline if the remote service group is in an OFFLINE state. RemoteFaulted.Indicates that the RemoteGroup resource returns an IntentionalOffline if the remote service group is OFFLINE|FAULTED. You can use these values in combinations with each other. You must set the IntentionalOffline attribute of the RemoteGroup resource type to 1 for this attribute to work properly. Default: "" Type and Dimension: string-vector OfflineMonitoringN ode Defines the cluster node that performs the offline monitoring of the remote service group. This is an internal attribute. Do not modify. About the ControlMode attribute In the ControlMode attribute, you can use these values, depending on your needs: OnOff, MonitorOnly, and OnlineOnly. OnOff Select the OnOff value of this attribute when you want the RemoteGroup resource to manage the remote service group completely. The username provided in the Username attribute should have administrator privileges for the service group on the remote cluster. 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. MonitorOnly
VCS infrastructure and support agents RemoteGroup agent 157 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 you set the AutoFailover attribute of the remote service group to 1. OnlineOnly 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. The username provided in the Username attribute needs to have administrator privileges for the remote service group. The Offline of the RemoteGroup resource does not offline the remote service group. 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 recommended 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. Sample scenario In this example, a local VCS cluster (front-end cluster) provides high availability for Web-services and a remote VCS cluster (back-end cluster) provides high availability for the database required by the Web-services. The cluster setup is as follows: ■ The local cluster is a two-node cluster, where local1 and local2 are the names of the two local nodes.
