LB Activation from VCD fails with the error: "Record Not Found"

Products

• VMware Avi Load Balancer
• VMware Cloud Director

Issue/Introduction

• In a VMware Cloud Director (VCD) environment, attempting to activate a load balancer for a T1 gateway backed by VMware Avi Load Balancer results in the error message: "Record Not Found.
• This occurs when navigating through the Tenant UI in VCD, under the following path: Tenant UI > Org VDC > Networking > Edges > Edge Gateway > Load Balancer > General Settings > Edit, and toggling the "Active" switch.

Environment

• VMware Avi Load Balancer
• VMware Cloud Director

Cause

• The failure occurs because VCD attempts to Modify the Tier 1 (T1) gateway with a new segment mapping within the NSX-T cloud, but this operation is dependent on modifying the cloud configuration on the Avi Load Balancer
• The modification process fails due to the presence of a stale Service Engine (SE) group template attached under the NSX-T cloud configuration in Avi.
• The stale SE group can be identified through the Avi controller's CLI(Bash Mode). Specifically, the octavius.ERROR log file located at /var/lib/avi/log/octavius.ERROR provides details about this failure

Resolution

To resolve the issue and successfully activate the load balancer, follow these steps:

• Access the Avi controller via CLI.

• In shell mode, run the following commands to remove the stale SE group template from the cloud configuration:

  configure cloud <cloud_name>

  no se_group_template_ref

  save

• After removing the stale SE group template, save the changes and exit.

• Return to VCD and try activating the load balancer again.
