I have maintence window coming up and I would like to see if it would be possbile to script this...

I would like to shut down all powered on VM's in a cluster . If VM tools are not installed, power off the VM.

In a second script, power on all VM's that were shut down or powered off from the previous script. I do not want to power on all VM's, only the ones that were running previously. I would also like to only power on 10 VM's at a time every 5 minutes (to avoid a boot storm and resource contention).

Let's start with the first script.

You could do something like this

$clusterName = <clustername>
$vms = Get-Cluster -Name $clusterName | Get-VM | where {$_.PowerState -eq "PoweredOn"}
$vms | where {$_.Guest.State -eq "NotRunning"} | Stop-VM -Confirm:$false
$vms | where {$_.Guest.State -eq "Running"} | Shutdown-VMGuest -Confirm:$false
$vms | Select Name | Export-Csv "C:\Temp\cluster-vm-stopped.csv" -NoTypeInformation

Guys,

Thanks for the example you show how to shutdown a cluster per cluster if you specify the cluster.

I'd like to modify the script to shutdown per datastore. But instead of shutting down a VM at a time. I'd like to shutdown 4 at a time.

When I use for-each it would do one at a time. Any suggestions or examples would be great.

For the 2nd script we use the .csv file from the 1st script.

Give this a try.

$start = Get-Date
$names = Import-Csv "C:\Temp\cluster-vm-stopped.csv"
$total = 0
while($total -le $names.Count){
  1..10 | %{
    if($names[$total]){
      Start-VM -VM (Get-VM -Name $names[$total]) -Confirm:$false -RunAsync
      $total++
    }
  }
  while((Get-Date - $start).TotalMinutes -lt 5){
    sleep 10
  }
  $start = Get-Date
}

Another sample :smileyhappy:

# Script 1 - Shut down VMs in cluster

$vms = Get-Cluster cluster02 | Get-VM 

$vmstools = $vms | Where { $_.PowerState -eq "PoweredOn"} | Get-View | Where { $_.GuestHeartbeatStatus -ne "gray"}
$vmsnotools = $vms |  Where { $_.PowerState -eq "PoweredOn"} | Get-View | Where { $_.GuestHeartbeatStatus -eq "gray"}
            
$vms | Select name | Export-CSV c:\tmp\delete\list.csv -NoTypeInformation 

$vmtools |  Shutdown-VMGuest -Confirm:false
$vmnotools | Stop-VM -Confirm:false

# Add code to check if all in $vmtools were powered down

# Script 2 - start previously powered off VMs
 
$i = 1
$vms_on = Import-CSV c:\tmp\delete\list.csv
ForEach ($vm in $vms_on) {
               Start-VM -VM $vm.name -whatif
               If (($i%10) -eq 0) {
                                    Write-host "Started " $i " VMs.  Taking a break."
                                    Sleep 300
                                    }
                $i = $i + 1
                }

You guys have help me before with my shutdown script which I have got from you guys anyway, I am looking to better it.

So this is what I would like to do but I can't becasue I don't know how to. I took this script from an upgrade vmware tools and instead would like to use some of its context to ShutDown VM's from a list.txt file, check to make sure they are down create a log file that they are down then once they are all down send an email.

I know I have to add probably a Sleep to wait for each one in here as well.

I really appreciate your help.

1. Get the VM's from a text file -

$colVMs = Get-Content "C:\list.txt" | % { Get-VM $_ | Shutdown-VMGuest -Confirm:$false }

2. Start the Shutdown process -

3. Create a log file -

$logFile = New-Item -ItemType File -Path "C:\Powershell\temp\power\VMware-PowerOff_$((get-date).toString('MM-dd-yyyy_hh.mmtt')).log"

4. Get the information on each machine PowerState -

foreach ($VM in $colVMs) {

$VMPower = $VM.PowerState

$VMName = $VM.name

$OS = (Get-VMGuest $VM)

$vmID = get-vm $VM | foreach {get-view $_.Id}

5. Check that the VMs are off -

if ($VMPower -notmatch "PoweredON") {

Write-Host $VMName `t "Powered OFF" -ForegroundColor Red

Add-Content -Path $logFile -Value ($VMName + "`t`tShutDown`t`tPowered OFF")

}

6. Send out an email with a log letting me know that they have ShutDown

send-mailmessage -SmtpServer "smtp.com" `

I guess I should have posted as a new Post since this one showed Answered?
