Issue/Introduction

• Cannot deploy VCF Operations for networks and VCF Operation for logs using Fleet Management UI
• Unable to select a vCenter within the VCF Management Infrastructure during VCF Operations for networks deployment (same also for VCF Operation for logs)
• The VCF Management > Settings > Deployment Targets shows duplicate vCenter domain entries

Environment

VMware Cloud Foundation 9.0.2.0

Cause

When adding a vCenter with wrong credentials and the Inventory Sync failed. You will need to retry the failed task with proper credentials. This step will add the vCenter properly and Status will be shown as Green.

However, the issue will appear when trying to add then same vCenter again without retrying the existing task which will add the same vCenter twice.

Resolution

The following workaround will require to remove the environment where the vCenter duplicates are placed on, and still associated to VCF Aria Operations.

2. SSH into Fleet Management appliance and enable Standalone Fleet Management UI with command:

touch /var/lib/vrlcm/UI_ENABLED

3. Login into the Fleet Management UI https://<FDQN or IP address>  with admin@local user

4. Goto the Fleet Management Swagger and search for the environment id which require to be deleted using Environment GET API.

GET  /lcm/lcops/api/v2/environments

    or alternatively from the Fleet Management UI select the VCF Operations and in the browser url you will get the environment id.

5. Delete the VCF Operations with:

DELETE /lcm/lcops/api/v2/environments/{environmentId}

Payload
{
  "controllerType": "string",
  "deleteFromInventory": true,
  "deleteFromVcenter": false,
  "deleteLbFromSddc": true,
  "deleteWindowsVMs": true
}

6. Goto the Tasks and Retry with skip option for the failed Delete Environment Task
7. Goto the Deployment Target and delete the vCenters
8. Goto VCF Operation UI and reregister the Fleet Management
