Changing network adapters

[richardbrown198]

Hi,

A little help please, as part of my script i am trying to change the backing on a list of vms which all have different portgroups, if they = this then change to that. Below is what i have i get no erros the script runs but the guest does not change and i have copied and pasted the variables from vCenter so should be no spelling issues.

foreach ($vm in $vmlist) {

    $adp = get-vm $vm | get-networkadapter

    if ($adp -eq $oldNet1){

        set-networkadapter -NetworkName $PG1 -confirm:$false

    }elseif ($adp -eq $oldNet2){

        set-networkadapter -NetworkName $PG2 -confirm:$false

    }elseif ($adp -eq $oldNet3){

        set-networkadapter -NetworkName $PG3 -confirm:$false

    }elseif ($adp -eq $oldNet4){

        set-networkadapter -NetworkName $PG4 -confirm:$false

    }

}

however if i run the one liner below it works fine.

get-vm $vm | get-NetworkAdapter | where {$_.NetworkName -eq $oldNet1} | set-networkadapter -NetworkName $PG1 -confirm:$false

If i actually put that last line in a foreach statement i can get it to work but not sure thats the best way to do it as it takes a while..

foreach ($vm in $vmlist) {

get-vm $vm | get-NetworkAdapter | where {$_.NetworkName -eq $oldNet1} | set-networkadapter -NetworkName $PG1 -confirm:$false

get-vm $vm | get-NetworkAdapter | where {$_.NetworkName -eq $oldNet2} | set-networkadapter -NetworkName $PG2 -confirm:$false

get-vm $vm | get-NetworkAdapter | where {$_.NetworkName -eq $oldNet3} | set-networkadapter -NetworkName $PG3 -confirm:$false

get-vm $vm | get-NetworkAdapter | where {$_.NetworkName -eq $oldNet4} | set-networkadapter -NetworkName $PG4 -confirm:$false

}

You have to provide a NetworkAdapter object to the Set-NetworkAdapter cmdlet.

It is a required parameter.

foreach ($vm in $vmlist) {

   $adp = Get-VM $vm | Get-NetworkAdapter

   if ($adp -eq $oldNet1){

   Set-NetworkAdapter -NetworkAdapter $adp -NetworkName $PG1 -confirm:$false

   }elseif ($adp -eq $oldNet2){

   Set-NetworkAdapter -NetworkAdapter $adp -NetworkName $PG2 -confirm:$false

   }elseif ($adp -eq $oldNet3){

   Set-NetworkAdapter -NetworkAdapter $adp -NetworkName $PG3 -confirm:$false

   }elseif ($adp -eq $oldNet4){

   Set-NetworkAdapter -NetworkAdapter $adp -NetworkName $PG4 -confirm:$false

   }

}

Thanks Luc,

I've run your code and it still does nothing....

If you have a string value in the $oldNet1, $oldNet2... variables,
you will probably have to do like this

foreach ($vm in $vmlist) {

   $adp = Get-VM $vm | Get-NetworkAdapter

   if ($adp.NetworkName -eq $oldNet1){

   Set-NetworkAdapter -NetworkAdapter $adp -NetworkName $PG1 -confirm:$false

   }elseif ($adp.NetworkName -eq $oldNet2){

   Set-NetworkAdapter -NetworkAdapter $adp -NetworkName $PG2 -confirm:$false

   }elseif ($adp.NetworkName -eq $oldNet3){

   Set-NetworkAdapter -NetworkAdapter $adp -NetworkName $PG3 -confirm:$false

   }elseif ($adp.NetworkName -eq $oldNet4){

   Set-NetworkAdapter -NetworkAdapter $adp -NetworkName $PG4 -confirm:$false

   }

}
