Abstract
A cluster of nodes are sequentially updated with new network configuration settings in order to maintain availability of the cluster during the update. In the sequential update, each node conditionally updates network configuration settings, tests connectivity, and retains an update to the configuration only if the node is able to restore connectivity suitable for operation in the cluster.
