Taking Exchange Virtual Servers or Exchange Resources Offline
Occasionally, you must take an Exchange Virtual Server or resource offline. For example, you might have to apply a service pack. In that case, you would bring each Exchange Virtual Server offline, and apply the service pack to the associated node.
You take Exchange Virtual Servers and Exchange resources offline the same way you do with cluster groups and Windows resources. For detailed instructions, see How to Take an Exchange Virtual Server or Exchange Resource Offline Using Cluster Administrator.
