Managing the NSX Manager Cluster

You can reboot an NSX Manager if it becomes inoperable. You can also change the IP address of an NSX Manager.

In a production environment, it is highly recommended that the NSX Manager cluster has three members to provide high availability. If you delete an NSX Manager and deploy a new one, the new NSX Manager can have the same or a different IP address.

Note: The primary NSX Manager node is the node that you create first, before you create a manager cluster. This node cannot be deleted. After you deploy two more manager nodes from the primary manager node's UI to form a cluster, only the second and the third manager nodes have the option (from the gear icon) to be deleted. For information about removing and adding a manager node, see Change the IP Address of an NSX Manager.
