Freezing and unfreezing service groups
Freeze a service group to prevent it from failing over to another system. This freezing process stops all online and offline procedures on the service group.
Note that if the service group is in ONLINE state and if you freeze the service group, then the group continues to remain in ONLINE state.
Unfreeze a frozen service group to perform online or offline operations on the service group.
