Check wether VIBs are installed or not on ESXi hosts in a cluster with VIB Report Script

In my last blog, I shared a Powershell script that can be used to remove VIBs from all ESXi hosts in a cluster. I have created a small Powershell script that you can run before and after removing of VIBs to check the availability of VIBs.

The output is displayed in an HTML file once the script is finished. The VIBs being checked are deﬁned in $arrayvibs. The location of the HTML file can be defined in $outputPath. The number of VIBs you can have checked depends on how many you define in $arrayvibs.

Here are a few examples of the HTML output files.

Example output before run VIB Check Report script to remove the VIBs “nenic” and “iavmd”.

Example output after run VIB Check Report script to remove the VIBs “nenic” and “iavmd”.

Please be aware that using this script is at your own risk!
