PowerCLI: Upgrading vHardware to vSphere Part 2: VM’s


image

Disclaimer: use this script at your own risk 😉

In part 1 you could find a script to upgrade your templates to hardware version 7. In this post you’ll find a script that will upgrade your VM’s to hardware version 7.

Note: This script will upgrade the VMware Tools if necessary and will shutdown the VM!!!!!

You can download the script here: upgrade-vhardware_vm and here: http://poshcode.org/1217

The script will perform the following actions:

  • Connect to vCenter
  • Get all the VM’s in the folder you need to specify
  • Create a CSV file with some info about the VM. I will post the content later.
  • Update the VMware Tools if necessary (The VM will restart after the installation)
  • Shutdown the VM
  • Upgrade the vHardware to version 7
  • Start the VM
  • Create an Excel sheet with an overview of the VM’s and their IP settings

During the process of the script, the VM will be unavailable for 5 minutes or less. So be sure that nobody uses the VM.

The beforeHWchange.csv will look like this:

The script in action:

The last step, the creation of an Excel sheet with an overview of the VM’s. Here you can see if the IP Address is changed or not.

To do list:

  • Create a proper VM report function (export to csv) so I can capture multiple network adapters.
  • Create a before Excel sheet with a nice overview of the environment.

    Arne, very nice script.

    One question from me:
    After the hardware upgrade, is it still needed to logon to every vm and have Windows detect new hardware devices and restart the vm?

    Arne, Have you ever created the “before” report? We have a mash up of network cards, VM hardware 4 & 7, and finally differing versions of vmware tools. Do you have a report that can put all of these in a CSV?

    I’ve made some changes to make it upgrade from v7 to v8 but i’m not sure if it will work or not, what do you think
