Configuring new build Host to be consistent

[FireDog7881]

This is one of my first scripts that I created to quickly build out ESXi hosts without having Host Profiles or Distributed Virtual Switches. The main reason for this script is to configure the Networking so our Portgroups are consistent. It also configures the host to use Round Robin as default for datastores as well as configure existing LUNs to use Round Robin (ESXCLI must be installed).

This script utilizes a CSV file to pull the portgroup names. The location of the CSV file is set in the variables.

This script asks you questions so you don't need to enter parameters into the command line, this is meant to be run interactively.

This script sets Host Attributes, you need to create the host attributes in vCenter before running this script.

This script assumes you have 4 NICs available for the Host.

It uses vswitch0 with vmnics 0 & 1 for Service Console and VMotion

Creates vSwitch1 and uses vmnics 2 & 3 for VM Traffic.

Creates vSwitch2 with no physical NICs for Internal communication to quarantine VMs if necessary.

Please comment and let me know if there are better ways to do what I am doing.

Thank you.
