Pause or Resume a Node in a Failover Cluster
Applies To: Windows Server 2008
When you pause a node, existing groups and resources stay online, but additional groups and resources cannot be brought online on the node. The usual reason to pause a node is so that you can apply software updates to the node.
If you need to perform extensive diagnosis or maintenance on a cluster node, it might not be workable to simply pause the node. In that case, you can stop the Cluster service on that node. For more information, see Start or Stop the Cluster Service on a Cluster Node.
Membership in the local Administrators group on each clustered server, or equivalent, is the minimum required to complete this procedure. Also, the account you use must be a domain account. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).
