64 Configuring Your System and Network
— 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.

Starting and Stopping Clustering Services
Note This section applies only if you have purchased a high-
availability 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.
