Well, I recently decided to rename a bunch of my Standard Port Groups, since they did no longer reflect the network they were providing. Since I’m a lazy bastard (well lazy as in click lazy), I wrote this little PowerCLI script:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 |
param( [string] $vcenter, [string] $cluster, [string] $oldpg, [string] $newpg, [string] $vlan ) # Add the VI-Snapin if it isn't loaded already if ( (Get-PSSnapin -Name "VMware.VimAutomation.Core" -ErrorAction SilentlyContinue) -eq $null ) { Add-PSSnapin -Name "VMware.VimAutomation.Core" } If ( !($vcenter) -or !($cluster) -or !($oldpg) -or !($newpg) -or !($vlan) ) { Write-Host `n "pg-cluster-rename: <vcenter-server> <cluster> <oldpg> <newpg>" `n Write-Host "This script renames each port group with the name <oldpg> to <newpg>" `n Write-Host " <vcenter-server> - DNS name of your vCenter server." `n Write-Host " <cluster> - Display-Name of the vCenter cluster, on which we are" Write-Host " gonna create the new portgroup." `n Write-Host " <oldpg> - Name of the old Port Group that is to be replaced (ie VLAN2)." `n Write-Host " <newpg> - Name of the new Port Group (ie PG-VLAN2-Produktion)." `n Write-Host " <vlan> - VLAN-ID for of the new port group." `n exit 1 } Connect-VIServer -Server $vcenter Get-Cluster $cluster | Get-VMHost | Get-VirtualSwitch -Name $vswitch | ` New-VirtualPortGroup -Name $pg -VLanId $vlan Get-Cluster $cluster | Get-VM | Get-NetworkAdapter | Where { $_.NetworkName -eq "$oldpg" } | ` Set-NetworkAdapter -NetworkName $newpg -Confirm:$false Get-Cluster $cluster | Get-VMHost | %{Get-View (Get-View $_.ID).configmanager.networkSystem} | %{ $_.RemovePortGroup($oldpg) } Disconnect-VIServer -server $vcenter -Confirm:$false |
This script basically takes a vCenter instance and a single cluster, then creates a new Port Group on each host, after which it reconfigures all VMs possessing a virtual NIC with that Port Group and then deletes the old Port Group.
Does not work, you don’t define $vswitch.
