NSX Manager and vCenter Server have a one-to-one relationship. For every instance of NSX Manager there is one vCenter Server, even in a cross-vCenter NSX environment.
About this task
Only one NSX Manager can be registered with a vCenter Server system. Changing the vCenter registration of a configured NSX Manager is not supported.
If you want to change the vCenter registration of an existing NSX Manager, you must first remove all NSX configuration, and then remove the NSX Manager plug-in from the vCenter Server system. For instructions, see Safely Remove an NSX Installation. Or you can deploy a new NSX Manager appliance to register with the new vCenter Server system.
The NSX management service must be running. In the NSX Manager web interface at https://<nsx-manager-ip>, clickto view the service status.
You must use a vCenter Server user account that is member of the Administrators group to synchronize NSX Manager with the vCenter Server system. If your vCenter password has non-ASCII characters, you must change it before synchronizing the NSX Manager with the vCenter Server sytem.
Verify that forward and reverse name resolution works and that the following systems can resolve each other's DNS names:
NSX Manager appliances
vCenter Server systems
Platform Services Controller systems
- Log in to the NSX Manager virtual appliance.
In a Web browser, navigate to the NSX Manager appliance GUI at https://<nsx-manager-ip> or https://<nsx-manager-hostname>, and log in as admin or with an account that has the Enterprise Administrator role.
- From the home page, click Manage vCenter Registration.
- Edit the vCenter Server element to point to the vCenter Server system's IP address or hostname, and enter the vCenter Server system's user name and password.
For the user name, the best practice is to enter email@example.com or an alternative account that you have created. Do not use the root account.
- Check that the certificate thumbprint matches the certificate of the vCenter Server system.
If you installed a CA-signed certificate on the CA server, you are presented with the thumbprint of the CA-signed certificate. Otherwise, you are presented with a self-signed certificate.
- Do not check Modify plugin script download location, unless the NSX Manager is behind a firewall type of masking device.
This option allows you to enter an alternate IP address for NSX Manager. Note that putting NSX Manager behind a firewall of this type is not recommended.
- Confirm that the vCenter Server system status is Connected.
- Required: If vSphere Web Client is already open, log out and log back in with the same Administrator role used to register NSX Manager with vCenter Server.
If you do not do this, vSphere Web Client will not display the Networking & Security icon on the Home tab.
Click the Networking & Security icon and confirm that you can see the newly deployed NSX Manager.
What to do next
VMware recommends that you schedule a backup of NSX Manager data right after installing NSX Manager. See NSX Backup and Restore in the NSX Administration Guide.
If you have an NSX partner solution, refer to partner documentation for information on registering the partner console with NSX Manager.
You can now install and configure NSX components.
