NSX – Configure NSX manager roles (Primary, Secondary, Standalone, Transit)

The primary NSX Manager runs the controller cluster. Additional NSX Managers are secondary. The controller cluster that is deployed by the primary NSX Manager is a shared object and is referred to as the universal controller cluster. Secondary NSX Managers automatically import the universal controller cluster. There can be one primary NSX Manager and up to seven secondary NSX Managers in a cross-vCenter NSX environment.

NSX Managers can have one of four roles:

  • Primary
  • Secondary
  • Standalone
  • Transit

Primary, Secondary and Standalone roles are easy to understand. The Transit role is used when a primary or secondary NSX Manager is changed to Standalone and there are remaining universal objects in existence.

To view the role of an NSX Manager, log in to the vCenter linked to the NSX Manager, and navigate to Home > Networking & Security > Installation and select the Management tab. The role is displayed in the Role column in the NSX Managers section. If there is no Role column shown, the NSX Manager has the standalone role.

To configure an NSX Manager as the Primary:

1. Log into the vCenter linked to the primary NSX Manager using the vSphere Web Client.

2. Navigate to Home > Networking & Security > Installation and select the Management tab.

3. Select the NSX Manager you want to assign as the primary and click Actions and then Assign Primary Role.

The selected NSX Manager is assigned the primary role.

To configure an NSX Manager as Secondary:

1. Log in to the vCenter linked to the primary NSX Manager.

2. Navigate to Home > Networking & Security > Installation and select the Management tab.

3. Click the primary NSX Manager. Then select Actions > Add Secondary NSX Manager.

4. Enter the IP address, user name, and password of the secondary NSX Manager.

5. Click OK.

6. Check that the certificate thumbprint matches the certificate of the vCenter Server.

After successful registration the role changes from Standalone to Secondary.

If your vCenter Server systems are in Enhanced Linked Mode, you can see the roles of all NSX Managers associated with those vCenter Server systems from the Home > Networking & Security > Installation tab.
