Resolution

1. Temporarily disable NSX Data Source within Aria Operations for Network (AON). Once disabled, the vRNI groups will automatically be removed from NSX.
   1. Login to the AON User Interface
   2. Go to Settings > Accounts and Data Sources > Data Collection
   3. Disable Data Collection
2. From within the NSX User interface, remove NSX from the required hosts
3. From within Aria Operations for Network User Interface enable Data Collection again. This will recreate vRNI groups.
