PowerShell script error....

Hello,

I found a script I want to use and of course since Im new to PowerShell, I get an error that the "Connect-VIServer" is not recognized as the name of a cmdlet. So basically Powershell does not recognzie line 12. Is there something I need to do to make PowerShell recognize that cmdlet?

Any help is greatly appreciated...

you need VMware vSphere™ PowerCLI along with PowerShell,which will have all the proper cmdlets

If you already have PowerCLI and you are not running the script from within the powercli prompt (i.e. you're running through vanilla powershell) then add the following lines to the very top of the script to load the VMware bits and pieces:

Add-PSSnapin -Name "VMware.VimAutomation.Core"

http://Reflection.Assembly::LoadWithPartialName("vmware.vim")
