Here is the scenario
PS C:\windows\system39> get-virtualportgroup
Name
Key
VLanId PortBinding NumPorts
----
---
------ ----------- --------
BDL-vbxx-PXE-BUILD
key-vim.host.PortGroup-BDL-... 3908
My-my-pg
key-vim.host.PortGroup-Vblo... 1098
key-vim.host.PortGroup-
0
BDL-99-Vmotion
key-vim.host.PortGroup-BDL-... 3906
My-my-pg_vmk
key-vim.host.PortGroup-Vblo... 1098
BDL-99-NAS
key-vim.host.PortGroup-BDL-... 3907
BDL-99-MGMT
key-vim.host.PortGroup-BDL-... 1193
BDL-99-MGMT_vmk
key-vim.host.PortGroup-BDL-... 1193
Now here you have a problem where the 3rd
portgorup has no name and thus cannot be delted from the GUI but
PS C:\windows\system39> $pg = get-virtualportgroup | where
vlanid -EQ 0
$pg
Name
Key
VLanId PortBinding NumPorts
----
---
------ ----------- --------
key-vim.host.PortGroup-
0
the above we can do. Now let us try to remove this
PS C:\windows\system39> $pg | Remove-VirtualPortGroup
-Confirm:$false
Remove-VirtualPortGroup : 4/8/9016 3:40:41 PM Remove-VirtualPortGroup The resource ' ' is in use.
At line:1 char:7
+ $pg | Remove-VirtualPortGroup -Confirm:$false

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:)
[Remove-VirtualPortGroup], VimException
+ FullyQualifiedErrorId :

And it won’t let us since it says it is busy. We have seen
this when there is a vmkernel in the portgroup that we are trying to delete.
Let us list the vmkernels shall we…
PS C:\windows\system39> Get-VMHostNetworkAdapter
Name Mac DhcpEnabled IP SubnetMask DeviceName
---- --- ----------- -- ---------- ----------
vmnic0
e0:0e:da:71:15:e6 False

vmk1 00:50:56:69:74:a8
False 199.168.906.99 955.955.955.0 vmk1
as you can see the vmk 8 is the culprit with no ip and
subnet mask to it.
PS C:\windows\system39> $vmk = Get-VMHostNetworkAdapter |
where Name -EQ vmk8
$vmk
Name Mac DhcpEnabled IP SubnetMask DeviceName
---- --- ----------- -- ---------- ----------
vmk8 00:50:56:6f:dd:cd
False
vmk8
so now we have got that vmk too. Let us remove that sucker
first.
PS C:\windows\system39> $pg = get-virtualportgroup | where
vlanid -EQ 0
$vmk = Get-VMHostNetworkAdapter | where Name -EQ vmk8
Remove-VMHostNetworkAdapter -Nic $vmk -confirm:$false
PS C:\windows\system39>
No errors but lets check anyway
PS C:\windows\system39> Get-VMHostNetworkAdapter

vmk8 has been officially sent to hell.
Lets remove the house (portgroup) where it was staying,
shall we?
PS C:\windows\system39> $pg = get-virtualportgroup | where
vlanid -EQ 0
$pg | Remove-VirtualPortGroup -Confirm:$false
PS C:\windows\system39> get-virtualportgroup
