Disabling a cluster node

You can temporarily remove a node from a cluster by disabling the cluster instance on that node. A disabled node is not synchronized with the cluster configurations. When the node is enabled again, the cluster configurations are automatically synchronized on it. For more information, seeSynchronization across cluster nodes.

A disabled node cannot serve traffic and all existing connections on this node are terminated.

Note

If the configurations of a disabled non-configuration coordinator node are modified (through the NSIP address of the node), the configurations are not automatically synchronized on that node. You must manually synchronize the configurations as described inSynchronizing Cluster Configurations.

To disable a cluster node by using the command line interface

在命令提示符处的节点disable, type:

disable cluster instance 

Note

To disable the cluster, run the disable cluster instance command on the cluster IP address.

To disable a cluster node by using the configuration utility

1. On the node that you want to disable, navigate toSystem > Cluster, and clickManage Cluster.
2. In theConfigurecluster instance dialog box, unselect theEnablecluster instance check box.

   Note

   To disable the cluster instance on all the nodes, perform the above procedure on the cluster IP address.
