PowerNSX has Remove-NsxSecurityTagAssignment but that removes all tags. I want to remove a single NSX Security TAG from a Single VM.

#This line will remove all TAGS from VM

Get-VM VM01 | Get-NsxSecurityTagAssignment | Remove-NsxSecurityTagAssignment

#This line will display only one tag

Get-VM VM01 | Get-NsxSecuritytagassignment | select-object @{Name="SecurityTag"; expression = {$_.securitytag.name}}, VirtualMachine | Where-Object {$_.SecurityTag -like '*SecurityTag01*'}

#This line will display only one tag but remove doesn’t work.

Get-VM TempWin2012R2 | Get-NsxSecuritytagassignment | select-object @{Name="SecurityTag"; expression = {$_.securitytag.name}}, VirtualMachine | Where-Object {$_.SecurityTag -like '*SecurityTag01*'} | Remove-NsxSecurityTagAssignment

Any help would be appreciated.

That is due to the Select in your pipeline.

The Select cmdlet produces another object that Remove-NsxSecurityTagAssignment can't handle.

Try like this

Thank You very much LucD.

This is what I did and it works with your help!

Get-VM VM01 | Get-NsxSecurityTagAssignment |

Where-Object {$_.securitytag.name -like '*SecurityTag01*'} |

Remove-NsxSecurityTagAssignment -Confirm:$false

I have attended a lot of your sessions at VMworld and you always amaze me.  THANKS!
