Need some help with PowerShell Script - Still Learning
Posted on 2016-08-18
I am making a script which will delete VMs in VSphere based on a list of machines.
However instead of turning off an active machine, I would like to skip it, and notify its been skipped because its active.
Here is my current script, which checks for active machines, but it just turns them off and then deletes them.
Can anyone help with this script which will use the active machines and skip them in the deletion command?
$VMs = (Get-Content c:\lists\servers.txt)
$vmObj = Get-vm $vms
foreach($active in $vmObj){
if($active.PowerState -eq "PoweredOn"){
Stop-VM -VM $active -Confirm:$false -RunAsync | Out-Null}
}
Start-Sleep -Seconds 7
foreach($delete in $vmObj){
Remove-VM -VM $delete -DeleteFromDisk -Confirm:$false -RunAsync | Out-Null}
Something like:
foreach($active in $vmObj){
if($active.PowerState -eq "PoweredOn"){
write-host "The machine $active is powered on and will not be deleted" }
Start-Sleep -Seconds 7
And then somehow remove the $active machines from the $delete list.
Help?

## $VMs = (Get-Content c:\lists\servers.txt) <-- this line is not working
$vmObj = Get-vm $vms
$newlist = $vmobj
foreach($active in $vmObj){
if($active.PowerState -eq "PoweredOn"){
write-host "The machine $active is powered on and will not be deleted. It will power down soon"
Stop-VM -VM $active -Confirm:$false -RunAsync | Out-Null
$newlist = $newlist | ? {$_.name -ne $($active.name)}
}
}
Start-Sleep -Seconds 7
foreach($delete in $newlist){
Remove-VM -VM $delete -DeleteFromDisk -Confirm:$false -RunAsync | Out-Null}
$vmObj = Get-vm $vms
$newlist = $vmobj
foreach($active in $vmObj){

Stop-VM -VM $active -Confirm:$false -RunAsync | Out-Null

}

Remove-VM -VM $delete -DeleteFromDisk -Confirm:$false -RunAsync | Out-Null}
If I am understanding correctly. If I don't want to actually turn off any VMs I can simply remove this line?
Stop-VM -VM $active -Confirm:$false -RunAsync | Out-Null
For example, I can be given a list of 200 VMs to delete. If any of these VMs are in the list by accident, I don't want to turn it off and delete it.
I just want to specify the name is turned on and will not be deleted, then the next function in the script will not execute for the turned on machine name.
Stop-VM -VM $active -Confirm:$false -RunAsync | Out-Null

Stop-VM will turn off the VM. so you # it out, then the line will not run.
and in fact, it will be easier to say you just want to delete anything which is not powered ON you can run something like this.

}
}
Thanks.
But I would like to know which were skipped due to being powered on. So that's why I added the write-host to it.
So at this point I just need to import the list, and I will test the above options.
I understand even if the delete command hits a powered on server it won't work. I would just like to avoid the errors from running a delete command on a powered on server.

Also why would this line not work to import names from a txt file? Ive never had an issue with this before
$vms = Get-Content -Path "c:\lists\servers.txt"
$vms = Get-Content -Path "c:\lists\servers.txt"

my fault. you are right, it will work. first line is working, i must be blind or mislook a line.
Anyway, if you want to know whether it is power on
you can immediately tell by doing
This command will tell you which server is powered on.
you don't need it in the loop.
