150 VCS infrastructure and support agents RemoteGroup agent With the RemoteGroup agent, you can monitor or manage a service group that exists in a remote cluster. Some points about configuring the RemoteGroup resource are: ■ ■ ■ ■ For each remote service group that you want to monitor or manage, you must configure a corresponding RemoteGroup resource in the local cluster. Multiple RemoteGroup resources in a local cluster can manage corresponding multiple remote service groups in different remote clusters. You can include the RemoteGroup resource in any kind of resource or service group dependency tree. A combination of the state of the local service group and the state of the remote service group determines the state of the RemoteGroup resource. Symantec supports the RemoteGroup agent when: ■ ■ ■ When it points to a global group The RemoteGroup agent must then map the state of the global group in the local cluster. When it is configured inside a local parallel service group The RemoteGroup resources on all cluster nodes monitor the same remote service group unless its attributes are localized. When it is configured inside a local failover service group For more information on the functionality of this agent, see the Veritas Cluster Server Administrator's Guide. Dependency As a best practice, establish a RemoteGroup resource dependency on a NIC resource. Symantec recommends that the RemoteGroup resource not be by itself in a service group. Agent functions Online Offline Monitor Depending on the ControlMode setting, this function brings the remote service group online. Depending on the ControlMode setting, this function takes the remote service group offline. Monitors the state of the remote service group. The true state of the remote service group is monitored only on the online node in the local cluster.
VCS infrastructure and support agents RemoteGroup agent 151 Clean Depending on the ControlMode setting, Clean takes the remote service group offline whenever the RemoteGroup resource faults. State definitions ONLINE Indicates that the remote service group is either in an ONLINE or PARTIAL state. If the ReturnIntOffline attribute is not set to RemotePartial, then the remote service group is either in an ONLINE or PARTIAL state. OFFLINE Indicates that the remote service group is in an OFFLINE or FAULTED state. The true state of the remote service group is monitored only on the online node in the local cluster. The RemoteGroup resource returns intentional offline if the attribute ReturnIntOffline is set to an appropriate value. FAULTED UNKNOWN Indicates that the remote service group has unexpectedly gone offline. Indicates that a problem exists either with the configuration or the ability of the RemoteGroup resource to determine the state of the remote service group.
