- Node Timeout: Timeout value for a heartbeat between nodes. If a heartbeat is not detected for this specified amount of time, the node awaiting/monitoring the heartbeat will determine that the node is unavailable and will commence cluster reformation and package failover. 5 Click OK. Starting and Stopping Clustering Services Note This section applies only if you have purchased a highavailability NAS solution. Once a cluster configuration exists, you can manually start clustering services. The cluster will not start automatically. You can start the clustering services with or without packages defined. The clustering services will automatically start any packages that you configured with Auto Start enabled. See "Adding a New Package" on page 86 for more information on configuring packages. When you stop the clustering services, all packages stop gracefully and the cluster stops. Stopping clustering services does not cause the systems to shut down or reboot. Upon completion of a clustering services stop command, the systems will be up but no packages will be running; therefore, all volume groups will be inactive and no storage will be accessible to client systems. You can configure the clustering services to automatically start when the system boots. By default, the clustering services auto-start feature is disabled and you must start clustering services manually. If you enable clustering services auto-start, clustering services will start automatically when the system boots. When you modify the clustering services auto-start setting, the setting will be mirrored on the other cluster nodes. See "Entering Node Settings" on page 61 if you want to change the auto-start feature. The Start/Stop Clustering Services screen allows you to turn clustering capabilities on or off. You must stop clustering services to change configuration information on your NAS server. Once you stop clustering services, you will be able to access your data through the physical IP address but not the virtual IP address. Caution All current connections to CIFS and NFS will be lost when you stop clustering services. 64 Configuring Your System and Network
