Automated ESXi Cisco UCS Firmware Upgrade using Powertool

I have completed a script that will allow you to put a host into maintenance mode, verify service profile based on MAC address, and then change your firmware policy.

Requirements for the Script:
Cisco Powertool 1.x or later
Vmware Powercli 5.x or later
Maintenance Policy is User Ack
Ensure your VMNIC0 is matched up with your first Vnic template in order.

Now for the script!
