Issue/Introduction

In an NSX-T manager cluster configured with VIP address, vIDM configuration gets repopulated automatically after removing vIDM configuration from NSX-T manager cluster.

Environment

VMware NSX-T

Cause

The issue happens when NSX-T manager cluster is configured with cluster VIP address.

Resolution

In order to remove vIDM configuration from an NSX-T manager cluster remove cluster VIP first.
Cluster VIP can be removed using the following API-

Using postman client:
POST: https://<nsx-manager-fqdn/IP>/api/v1/cluster/api-virtual-ip?action=clear_virtual_ip

Using Curl:
curl -k -H "Content-Type:application/json" -u admin -X POST https://<nsx-manager-fqdn/IP>/api/v1/cluster/api-virtual-ip?action=clear_virtual_ip

Once cluster VIP is removed vIDM configuration can be removed from manager.
Add cluster VIP back after vIDM configuration is removed.

Additional Information

Removing cluster VIP will impact API/UI requests to cluster VIP address.
