Replace <vCenterServer> with the name or IP address of your vCenter server, <Username> with your vCenter username, <Password> with your vCenter password, and  $VMServerName with the name of your VM.
This script connects to your vCenter server using Connect-VIServer, finds your VM using Get-VM, shuts down your VM using Stop-VMGuest, waits for the shutdown to complete with verification using a do...until loop and Start-Sleep cmdlet, adds hot plug and hot swap capability to your VM guest using Set-VM, turns on your VM using Start-VM, waits for it to complete with verification using a do...until loop and Start-Sleep cmdlet, and disconnects from your vCenter server using Disconnect-VIServer.
Please note that this script assumes that you have already installed VMware PowerCLI on your system. If you haven’t installed it yet, you can download it from VMware’s website.
