To resize VMs using PowerShell with PowerCLI from a csv list, first install the software:




Then create a list of servers to resize and save it as a CSV file in C:\temp\VMs.csv:






Save the below as Something.PS1 and run from PowerCLI

Note: Change VCENTRE to your vCentre, this script will TURN THE SERVER OFF then give each VM two CPUs, one socket and 5GBs of RAM.


$me = Get-Credential

connect-viserver "VCENTRE" -User $me

$vms = get-content C:\Temp\VMs.csv

ForEach ($vm in $vms){

$vms | Shutdown-VMGuest –Confirm:$False

Sleep 60

$vms | Set-VM –MemoryGB 8 –NumCpu 2 –Confirm:$False

$vms | Start-VM

As per the title:

# All hosts connected in vCenter
$scope = Get-VMHost     
#OR specify a cluster
#$scope = Get-Cluster -Name 'Vsphere.Cluster01' | Get-VMHost

foreach ($esx in $scope){
Write-Host "HostName:", $esx
$hbas = Get-VMHostHba -VMHost $esx -Type FibreChannel
foreach ($hba in $hbas){
$wwpn = "{0:x}" -f $hba.PortWorldWideName
Write-Host `t $hba.Device, "|", $hba.model, "|", "World Wide Port Name:" $wwpn
