Issue/Introduction

SDDC Manager VI Domain deletion fails with error

Failed to remove vmknics from host esxi-1.example.com

Entities deployed with a network pool may show a warning message indicating duplicate IP addresses if the network pool was deployed with any used IP addresses. 

Additionally, some workflows may fail due to duplicate IP addresses that have gone undetected.

Environment

VMware Cloud Foundation 5.2

Cause

When creating a network pool, the IP addresses provided are not validated to ensure that they are not in use.

SDDC Manager does validate the included IPs for a new network pool against other network pools and against all other network types (vSAN, NFS, and so on) being added to the new network pool. 

However, it does not validate them against other components that are already deployed in the VMware Cloud Foundation instance (for example, ESXi hosts, NSX Managers, and so on). 

This can result in duplicate IP address errors or failed workflows.

Resolution

Update SDDC Manager Network Pool To Reflect The Correct Used State
