Forming an NSX Manager or Global Manager cluster provides high availability and reliability. You can use the join command to create a cluster.
Prerequisites
-
To create an NSX Manager cluster, deploy three nodes to create the cluster.
-
To create a Global Manager cluster, deploy three nodes to create the cluster. However, if your Global Manager has NSX-T Data Center 3.0.0 installed, deploy only one node, and do not form a cluster. See Install the Global Manager.
Procedure
Results
Verify the result by running the get managers command on your hosts.
host> get managers
- 192.168.110.47 Connected
In the NSX Manager UI in Fabric > Node > Hosts, verify that the host's MPA connectivity is Up.
You can also view the fabric host's state with the GET https://<nsx-mgr>/api/v1/fabric/nodes/<fabric-node-id>/state API call:
{ "details": [], "state": "success" }
The management plane sends the host certificates to the control plane, and the control plane pushes control plane information to the hosts.

You can see this with the esxcli network ip connection list | grep 1234 command.

user@host:~$ netstat -anp --tcp | grep 1234

Create a transport zone. See Create a Standalone Host or Bare Metal Server Transport Node.
