WARNING: Parameter 'VM' is obsolete. This parameter no longer accepts multiple values.

[jamesreinke2]

When running the script below

#import list of servers from text file

$Servers = Get-Content -Path “c:\VMlist.txt”

# Take snapshot of each vm

foreach($Server in $Servers){

Get-VM -Name $Server | New-Snapshot -Name "Take 2" -Description "blah blah blah" # -Quiesce -Memory

}

I recieve this error "WARNING: Parameter 'VM' is obsolete. This parameter no longer accepts multiple values."

Is there anyway around this or is thee a better way?

The message might be a bit misleading.

The VM parameter is not obsolete, only the possibility to pass multiple values (an array) on the parameter.

Hello,

What is the solution to pass multiple VM in txt file ?

Thanks for return.

Not sure what you mean?
On the Get-VM Name parameter you can still pass an array of names.
On the New-Snapshot VM parameter you can only pass 1 VM.
But if you are using both in a pipeline, the New-Snapshot will only get 1 VM object per call.

The following for example should still work.

Get-VM -Name (Get-Content -Path .\vmnames.txt) |
New-Snapshot -Name Test

Hello again LuD !

Thanks for your reply.

In fact : many days to try to understand why my very simple script didn't work :

$vmlist = Get-Content -Path "C:\Powercli\Powercli_VMWARE\Scripts\Checked\vmnames.txt"
foreach($vmname in $vmlist){
Get-VM -Name $vmname }

The error message : (see many many times in forum...)

The real reason of this trouble IS NOT THE SCRIPT but the file format about... TXT FILE !

YES be careful that the response file is well written in UTF-8 FORMAT !
