VCD – Force delete network

In our v2t conversion, the NSX for Cloud Director migration tool has had some issues when doing cleanup. One of them is that it cant delete the old NSX-V backed network even though there is nothing left in VCD using it. The error message can be seen below.

I found someone else having this problem, where they discovered a forceful way to delete the network. I have used this but wrapped it in Powershell instead. In my case, it can get the network URN from the log of the migration tools. Else you can also easily see the URN from the GUI URL when in the context of the network.

### Variables
$vcdUrl = "https://vcd.ramsgaard.me"
$apiusername = "@system"
$password = ''
$networkUrn = "urn:vcloud:network:ce108a33-fa5c-4cae-8c16-60edd536ad20"

### Auth against API and enable TLS1.2 for PowerShell
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $apiusername,$password)))
[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]::Tls12
$auth =Invoke-WebRequest -Uri "$vcdUrl/api/sessions" -Headers @{Accept = "application/*;version=36.0";Authorization="Basic $base64AuthInfo"} -Method Post

### Get VirtualWire
$virtualWire = Invoke-RestMethod -Uri "$vcdUrl/cloudapi/1.0.0/orgVdcNetworks/$($networkUrn)" -Headers @{Accept = "application/json;version=36.0";Authorization="Bearer $($auth.Headers.'X-VMWARE-VCLOUD-ACCESS-TOKEN')"} -Method GET
$virtualWire

### Delete VirtualWire
$deleteStatus = Invoke-RestMethod -Uri "https://vcd.hostcenter.dk/cloudapi/1.0.0/orgVdcNetworks/$($networkUrn)?force=true" -Headers @{Accept = "application/json;version=36.0";Authorization="Bearer $($auth.Headers.'X-VMWARE-VCLOUD-ACCESS-TOKEN')"} -Method DELETE
$deleteStatus

Above PowerShell is used at your own risk 🙂
