The configurations that are available on the configuration coordinator are automatically propagated to the other cluster nodes and therefore all cluster nodes have the same configurations.
NetScaler appliance allows only a few configurations to be performed on individual cluster nodes through their NSIP address. In these cases, you must ensure configuration consistency manually across all nodes in the cluster. These configurations are not propagated across the other cluster nodes. For more information on operations supported on each cluster nodes, see “Operations Supported on Individual Cluster Nodes”.
shutdown. Shuts down only the configuration coordinator.
reboot. Reboots only the configuration coordinator.
rm cluster instance. Removes the cluster instance from the node that you are executing the command on.
The quorum must be configured on cluster instance.
The majority of the cluster quorum with (n/2 + 1) of the cluster nodes must be active for the cluster to be operational.
A cluster can run with a minimum number of nodes when majority rule (n/2 + 1) is relaxed.
Full synchronization. If the difference between configurations exceeds 255 commands, all the configurations of the configuration coordinator are applied to the node that is rejoining the cluster. The node remains operationally unavailable for the duration of the synchronization.
You can also manually synchronize the configurations and files. For more information, see “ Synchronizing Cluster Configurations” and “ Synchronizing Cluster Files”.
