Welcome to my first blog of 2021! Its been a crazy year so far, but glad to be back writing. This issue is one that has been bothering me for some time in my vSphere 7 environment. Every time I logged into the vSphere Client i got the following error. “Error downloading plug-in. Make sure that the URL is reachable and the registered thumbprint is correct.” I finally had a few moments to research the issue and resolve it.

Error: ‘integrity.fault.HostPatchInvalidVendorCode’.” Let’s take a look how we can resolve this issue and be able to sync the latest updates.

In previous blogs, I covered how to update your VCSA using PowerCLI and with Postman. I also had multiple code sessions at VMworld 2019 where I got great feedback on the module. It’s been a while since I have looked at the module, and time has passed so I thought it was due for an update. The module will no longer need to be manually imported, it is now located in the Powershell Gallery!

Previously I covered how to use the VCSA Installer to do a scripted upgrade and then I covered Patching the vCenter Server Appliance (VCSA) using the REST API - Part 1 (Postman Collection) However, after learning recently how to call API’s from Powershell I thought to myself, why not write a Powershell Module for this?

Introduction

Using tools such as Postman can make it utilizing API’s a bit easier, but you still need to be familiar with a separate tool or UI. I was able to develop my own version and build my first Powershell Module that you can use to patch the VCSA in a simple …
