Stale NSX service instances after service deployment removal

Products

• VMware vDefend Firewall

Issue/Introduction

You are using NSX with Service Insertion (SI).

After removing SI and deploying a new service, alarms are present for "partner channel down" on some transport nodes.

In the UI under System > Service Deployments > Service Instances, some instances are showing a status of "Not Available":

Using API calls to remove the above instance fails due to child objects.

Environment

VMware NSX Data Center with Service Insertion.

Cause

When uninstalling the service deployment the following Corfu tables still have entries:

corfu_tool_runner.py --tool corfu-browser -o showTable -n nsx -t ServiceInstance
corfu_tool_runner.py --tool corfu-browser -o showTable -n nsx -t InstanceRuntime
corfu_tool_runner.py --tool corfu-browser -o showTable -n nsx -t InstanceEndpoint

This is caused by stale references in the NSX database which require removal.
