Simple Way to Delete all Snapshots on vSphere

Have our virtualization environment free of snapshots is a best practice to prevent low storage problems and performance degradation.

Check you environment for snapshots older than 7 day's, using the command:

Get-VM| Get-Snapshot |Where {$_.Created -lt (Get-Date).AddDays(-7)}| Select-Object VM,Name,Created,@{N="SizeGB";E={[math]::round($_.SizeGB, 1)}} | FT

Delete all snapshots for a specific VM run:

Get-VM MYVM-NAME| Get-Snapshot | Remove-Snapshot -RemoveChildren -Confirm:$False

If you want delete all snapshots for all VM's use:

Get-VM | Get-Snapshot | Remove-Snapshot -RemoveChildren -Confirm:$False

Sometimes delete snapshots fail in consolidation process and snapshot manager don't show snapshots. To check if all VM's are OK run:
```
Get-VM | Where-Object {$_.Extensiondata.Runtime.ConsolidationNeeded}
```

To start consolitation process execute:

Get-VM | Where-Object {$_.Extensiondata.Runtime.ConsolidationNeeded} | foreach {$_.ExtensionData.ConsolidateVMDisks_Task()}
