Delete/Create Snapshots

[SirHaschke]

Hi,
i try the following script to delete and create snapshots......

#VMware PowerCLI Modul Import
Import-Module VMware.PowerCLI

#Verbindung zum vCenter
Connect-VIServer -Server vcentername

#Löschen aller Snapshots mit dem Namen "Automatische Snapshot..."
Get-VM | Get-Snapshot | where {$_.name -like "Automatische Snapshot Sicherung Testumgebung (24h)"}| Remove-Snapshot -Confirm:$false

#Erstellen neuer Snapshots mit dem Namen "Automatische Snapshot..."
Get-VM -Location "Testumgebung" | New-Snapshot -Name "Automatische Snapshot Sicherung Testumgebung (24h)"

#Verbindung zum vCenter trennen
Disconnect-VIServer -Confirm:$false

But i get this error:
PS C:\Skripte> Get-VM | Get-Snapshot | where {$_.name -like "Automatische Snapshot Sicherung Testumgebung (24h)"}| Remove-Snapshot -Confirm:$false
Remove-Snapshot : 24.06.2021 14:29:15 Remove-Snapshot Ein Aufrufziel hat einen Ausnahmefehler verursacht.

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Remove-Snapshot], VimException

I use vsphere 7.x

Can someone tell me why i get this error?

Which PowerShell version?
From which platform?
Which PowerCLI version?

Do you get the same exception when the Culture is set to en-US?

[SirHaschke]

PS 5.1.14393.3866 from a Microsoft Server 2016.
PowerCli 6.0 Rel. 1 build 2548067

[LucD]

That is a very old PowerCLI version.
Can you upgrade?

Do you get the same from all platforms where you run this?

[SirHaschke]

I try this:

Install-Module -Name VMware.PowerCLI

But nothing happend.
How can i upgrade my powercli?

[LucD]

Have a look at Welcome PowerCLI to the PowerShell Gallery – Install Process Updates and Updating PowerCLI through the PowerShell Gallery

But also be aware that there are known issues with PowerCLI when the Culture is not en-US.

[SirHaschke]

Thanks.....

Sorry, i think V. 12.3.0 is installed.

[LucD]

That is the version from the Gallery.
You would need to do

Get-Module -Name VMware* -ListAvailable

to see what you have installed on your station.

[LucD · Accepted solution]

It looks like you have a mix of 6 and 12.3, that will not work
You should clean up (delete all those folders and then install again).
But that process is described in the posts I linked to earlier.

I have removed the old one and installed the new powercli.
Now it works fine.....
Thanks a lot.
