Postpone the resolution of resource-related problems that occur while a service group is being brought online or taken offline. You must have the role of cluster administrator or service group administrator, or service group operator to flush a service group.
Flushing a service group halts the current operation on the resources yet to be brought online or taken offline. Flushing a service group typically leaves the cluster in a partial state. After flushing a service group, you can resolve the issue with the problematic resource.
The menu is populated with system from the service group system list, which contains the systems on which the service group is configured.
