You can add, edit, or delete a virtual server in a deployed NSX load balancer.

The following considerations apply to deployments that originated in vRealize Automation 7.2 or earlier:

  • Load balancer reconfiguration is limited to deployments that contain a single load balancer.

  • The Items detail page for any load balancer in a deployment displays the virtual servers that are used by all the load balancers in the deployment. For more information, see Knowledge Base Article 2150276.

  • The Reconfigure Load Balancer operation is not supported for deployments that were upgraded or migrated from vRealize Automation 6.2.x to this vRealize Automation release.

For upgraded load balancers and load balancers deployed in the current vRealize Automation release, do not edit a virtual server and add a virtual server in the same request. For more information, see Knowledge Base Article 2150240.

If you submit a request to reconfigure a load balancer while another action is being performed on the deployment, for example when a scale out operation on the deployment is in progress, reconfiguration fails with a supporting message. In this situation, you can wait until the action is finished and then submit the reconfiguration request.


If the blueprint associated with the deployment is imported from a YAML file that contains an on-demand load balancer with a value in the name field that is different from the value in the ID field, the Reconfigure action fails. To enable the load balancer reconfiguration option for a deployment that is based on an imported blueprint, perform the following steps in the blueprint to allow post-provisioning actions for load balancer components in future deployments.

  1. In the vRealize Automation consol, select the blueprint.

  2. Click Edit and change the blueprint name. This sets the name and embedded ID to the same value.

  3. Select the load balancer component in the blueprint.

  4. Click Edit and re-enter the component name. This sets the name and embedded ID to the same value.

  5. Repeat for all load balancer components in the blueprint.

  6. Save the blueprint.

When you provision a new deployment using the edited blueprint, the reconfigure load balancer action works. To avoid this issue, ensure that all YAML files have identical name and ID values for all load balancer, network, and security components prior to importing them.

You should not manage vRealize Automation-administered NSX objects outside of vRealize Automation. For example, if you modify the member port of a deployed NSX load balancer in NSX, rather than in vRealize Automation, then NSX data collection breaks association between the deployed machine and its otherwise associated load balancer member pool. Scale in and scale out operations also produce unexpected results if a deployed load balancer member port is changed outside of vRealize Automation.

For information about the settings that are available when you add or edit a virtual server, see Add an On-Demand Load Balancer Component.

When you reconfigure a load balancer in vRealize Automation, some of the settings that were configured in NSX and that are not available as settings in vRealize Automation, are reverted back to their default value. After you run the load balancer reconfigure action in vRealize Automation, verify and update as needed the following settings in NSX:

  • Insert-X-Forwarded for HTTP Header

  • HTTP Redirect URL

  • Service Monitor Extension


  • Log in to vRealize Automation as a machine owner, support user, business group user with a shared access role, or business group manager.

  • Verify that you are entitled to reconfigure load balancers in a deployment. The required catalog entitlement is Reconfigure (Load Balancer).


  1. Select Items > Deployment.
  2. Locate the deployment and display its children components.

  3. Select the NSX load balancer to edit.

  4. Select Reconfigure from the Actions menu.
  5. Add, edit, or remove virtual servers.

  6. When you have finished adding, editing, or deleting virtual servers click Submit to submit the reconfiguration request.
