VM Inventory PowerCLI script for DR Purposes

I know that there have been a number of blog posts in the past about creating inventories of VMs within an environment, showing various details  about the environment… I have even used some of them myself in the past.

The script that I have pulled together and enhanced (from various sources) was designed to provide information that can be used in the event of a disaster and the virtual machines needed to be registered back into the environment from the datastores.  There is an additional script that I discovered which allows you to register all VMs on a particular datastore into the environment, and this works quite well (I’ll post this information separately) but sometimes there may be a requirement to just register a few of the VMs and therefore this information could be very useful and reduce the time to recover the VMs.

Unfortunately, I’m not a Powershell or PowerCLI expert and therefore there may be a more efficient way to perform this task, especially as this task can take around 3 hrs to complete on an environment consisting of around 700 VMs, and therefore in my environment, I only run this script once a week.  There are two files that are created at the end of the script, a CSV file which will allow you to manipulate the information and a formatted html page.  The html page looks similar to below (all references to particular server names have been removed):

This script runs on PowerCLI 6.5 Update 1.  Items in bold and italic should be changed for your environment.

Here’s the script:

get-module -ListAvailable VM* | Import-Module

connect-viserver vcenterservername
