The first time you savesettings on the Cluster Settings page, the Cluster Settings UUID field displays the UUID of theanchor stream that contains cluster settings.The following figure shows an example.You can optionally create an empty anchor stream in the cluster during initial configuration and setthat UUID as the clusterSettingsUUID in advance of any actual updates.WarningIf you are using a CSN, immediately enter cluster settings UUID on the Configurationpage under the Content Storage tab page of the CSN Console. If you are not using aCSN, immediately enter the cluster settings UUID in your node or cluster configurationfile. If you don't save the UUID, unpredictable behavior can result, including losing all yourcluster-wide settings when you reboot the node.NoteDell recommends you do not set cluster-wide persisted parameters in individual nodeconfiguration files because these values must be the same for the whole cluster. Anyvalues specified in a node configuration file are overridden by the cluster settings from theAdmin Console.The clusterSettingsUUID parameter enables all nodes in the cluster to use the same settingsevery time they reboot. Cluster nodes broadcast cluster settings over multicast. The reason
