Last week I attended a Magirus course on administrating you VMware environment using PowerCLI, and below is some of the small scripts I created.
These code sniplets will help you manage your VMware environment and give you some ideas of how powerful the VMware PowerCLI really is.
I’m sure VMware will add even more CMDLETS to the PowerCLI in the feature.
Get the latest PowerCLI here.
A function to load different PSSnapins.
Put it in the beginning of all you Powershell scripts,
to load the different PSSnapin you need.
function LoadSnapin{
param($PSSnapinName)
if (!(Get-PSSnapin | where {$_.Name -eq $PSSnapinName})){
Add-pssnapin -name $PSSnapinName
}
}
LoadSnapin -PSSnapinName "VMware.VimAutomation.Core"
