Assign VM Tag IF

[pamiller21]

How do I go about doing things like:
1) Assign this tag if....connected to these portgroups
2) Assign this tag if....within this folder

[LucD]

These both follow somewhat the same layout.

1) Something like this.
Note that this is very basic. There is, for example, no test if that Tag was already assigned.

$vmName = 'MyVM'

$tgtPG = 'PG'

$tagCategory = 'cat'

$tagName = 'whatever'

$tag = Get-Tag -Name $tagName -Category $tagCategory

if(Get-VM -Name $vmName -PipelineVariable vm | Get-NetworkAdapter | where{$_.NetworkName -eq $tgtPG}){

    New-TagAssignment -Entity $vm -Tag $tag -Confirm:$false

}

2) Same logic here

$vmName = 'MyVM'

$folderName = 'MyFolder'

$tagCategory = 'cat'

$tagName = 'whatever'

$tag = Get-Tag -Name $tagName -Category $tagCategory

if(Get-VM -Name $vmName -PipelineVariable vm | where{$_.Folder.Name -eq $folderName}){

    New-TagAssignment -Entity $vm -Tag $tag -Confirm:$false

}

I am looking at your port group tagging and I would like to have it scan the entire VM collection and anything attached to these portgroups get this tag, so I altered it, but I am missing something on how it gets all the VMs, but needs to individually tag.  Here is what I have:

$tgtPG = 'Corp-61'

$tagCategory = 'IP Use'

$tagName = 'Internal IP'

$tag = Get-Tag -Name $tagName -Category $tagCategory

if(Get-VM | Get-NetworkAdapter | where{$_.NetworkName -eq $tgtPG}){

    New-TagAssignment -Entity $vm -Tag $tag -Confirm:$false

}

I really appreciate this!

[LucD]

Try with a nested Where-clause

$tgtPG = 'Corp-61'

$tagCategory = 'IP Use'

$tagName = 'Internal IP'

$tag = Get-Tag -Name $tagName -Category $tagCategory

Get-VM -PipelineVariable vm | where{Get-NetworkAdapter -VM $_  | where{$_.NetworkName -eq $tgtPG}} |

ForEach-Object -Process {

    New-TagAssignment -Entity $vm -Tag $tag -Confirm:$false

}

I have been testing this and it mostly works, but the replicas that I have generated with veeam are attached to the portgroup, but the NICs are disconnected so the script doesn't see them.  Is there a way to allow that?

[LucD]

Is there a way to recognise the replica and find the original VM for which they are a replica?

[pamiller21]

Sure, they are <IDENTICAL_VM NAME>_replica

[LucD]

Try like this

$tgtPG = 'Corp-61'

$tagCategory = 'IP Use'

$tagName = 'Internal IP'

$tag = Get-Tag -Name $tagName -Category $tagCategory

Get-VM -PipelineVariable vm | where{Get-NetworkAdapter -VM $_  | where{$_.NetworkName -eq $tgtPG}} |

ForEach-Object -Process {

    New-TagAssignment -Entity $vm -Tag $tag -Confirm:$false

    Get-VM -Name "$($vm.Name)_replica" -ErrorAction SilentlyContinue |

    New-TagAssignment -Tag $tag -Confirm:$false

}

I am trying to apply tags via folders, but they are not searching recursively and not sure how to make that work.

### Mgmt ###

$folderName = 'Mgmt'

$tagCategory = 'Admin'

$tagName = 'Team Tag'

$tag = Get-Tag -Name $tagName -Category $tagCategory

Get-VM -PipelineVariable vm | where{$_.Folder.Name -eq $folderName} |

ForEach-Object -Process {

    New-TagAssignment -Entity $vm -Tag $tag -Confirm:$false

    Get-VM -Name "$($vm.Name)_replica" -ErrorAction SilentlyContinue |

    New-TagAssignment -Tag $tag -Confirm:$false

[LucD]

Do you mean you have other folders below the folder 'Mgmt'?

And VMs in those folders should also be tagged?

[pamiller21]

Correct!

[LucD]

It's not pretty, but try like this

### Mgmt ###

$folderName = 'Mgmt'

$tagCategory = 'Admin'

$tagName = 'Team Tag'

$tag = Get-Tag -Name $tagName -Category $tagCategory

$folder = Get-Folder -Name $folderName

$folders = @($folder)

$folders += Get-Folder -Location $folder

Get-VM -Location $folders -PipelineVariable vm

ForEach-Object -Process {

    New-TagAssignment -Entity $vm -Tag $tag -Confirm:$false

    Get-VM -Name "$($vm.Name)_replica" -ErrorAction SilentlyContinue |

    New-TagAssignment -Tag $tag -Confirm:$false

}
