NSX-T Data Center 2.4 and later support the deployment of multiple NSX Manager nodes to form a cluster in a single NSX-T Data Center instance. If you want to use an NSX Manager cluster with VMware Integrated OpenStack, add the IP addresses of all cluster nodes to your deployment configuration.

Note: The following limitations apply to the NSX Manager cluster:
  • An NSX Manager cluster provides high availability for a single NSX-T Data Center instance. Multiple instances of NSX-T Data Center cannot be used with the same VMware Integrated OpenStack deployment.
  • In the VMware Integrated OpenStack deployment, after configuring the 3 NSX-T managers, if you make any changes to the NSX-T manager, you can see that all the configurations on this page are displayed correctly, except the NSX Policy configuration, which is still loading.

Prerequisites

Create the NSX Manager cluster in NSX-T Data Center. See Deploy NSX Manager Nodes to Form a Cluster from UI.

Procedure

  1. Log in to the Integrated OpenStack Manager as the root user. 
    ssh root@mgmt-server-ip
  2. Modify the Neutron configuration for your deployment. 
    viocli update neutron
  3. In the nsx section, set the value of the nsx_api_managers parameter to the IP addresses of each node in the NSX Manager cluster, separated by commas. 
    nsx_api_managers: parent-manager-ip,manager-node2-ip,manager-node3-ip

What to do next

If the IP address of any node changes, or if you add or remove nodes in your NSX Manager cluster, you must modify the Neutron configuration to include the updated IP address information.
