When a service group is brought online or taken offline, the resources within the group are brought online or taken offline. If the online operation or offline operation hangs on a particular resource, flush the service group to clear the WAITING TO GO ONLINE or WAITING TO GO OFFLINE states from its resources. Flushing a service group typically leaves the service group in a partial state. After you complete this process, resolve the issue with the particular resource (if necessary) and proceed with starting or stopping the service group.
The flush operation does not halt the resource operations (such as online, offline, migrate, and clean) that are running. If a running operation succeeds after a flush command was fired, the resource state might change depending on the operation.
To flush a service group from Cluster Explorer
Click the cluster in the configuration tree, click the Service Groups tab, and right-click the service group icon in the view panel.
