Snapshots with PowerCLI

[bseymour]

I use this script to create snapshot of servers from an excel list. Can someone help with changing this so that it looks at a list of IP Addresses instead?

Checking to see if I understood the question.

You want to find the VMs based on their IP addresses, which are in the CSV ?

And once you have the VM, do the same snapshot removal/creation steps.

That is correct.

Try something like this

The link between the VMs and the IP addresses is stored in a hash table for easy reference.

$ipTab = @{}
foreach($vm in (Get-VM | Where {$_.Guest.IPAddress})){
    $vm.Guest.IPAddress | %{
        $ipTab.Add($_,$vm)
    }
}
$snapName = "maintenance_mm_dd_yy"

Import-Csv iplist.csv -UseCulture | %{
    if($ipTab.ContainsKey($_.IPAddress)){
        $snap = Get-Snapshot -VM $ipTab[$_.IPAddress] -ErrorAction SilentlyContinue
        if($snap){
            Remove-Snapshot -Snapshot $snap -Confirm:$false
        }
        New-Snapshot -Name $snapName -VM $ipTab[$_.IPAddress] -Confirm:$false
    }
}

Note that the script doesn't contain any extra logic to handle VMs that have more than 1 IP address

The same same snapshot will be taken multiple times.
