In my environment I have 11 Remote Locations that each have one ESXi host. I had a problem with ILO firmware updates the other day where I had to reboot these remote hosts. I really didn’t want to use the VIC to click on each of the VMs to shut them down, so using a lot of help from mpreston’s site I came up with a script that will shut down all of my VMs and then when ready, start the VMs again. My script shuts down “Front End” VMs first, then DB VMs, and then finally DCs. I have a modified version that allows me to do the same for my Datacenters that I will share later. You might have to edit the script if your database and or DCs are named differently.

Now that you have rebooted your hosts, it is time to start all the VMs again. You are going to use the dame variable that we created above.

You remote locations should be back up!
