Sometimes you need to test something in your lab and you need a 1000 test users.  For this, I created a simple Powershell script. Feel free to use.

Make sure to set the correct variables and that the OU exists!

VCSA CLI install error: format requires a mapping

While writing a standard vCenter installation procedure for a customer, I was testing the CLI installation of the Platform Service Controller (PSC) for VMware vCenter 6.5.

I really love the CLI installation method, it enables you to perform the same install procedure over and over again. If you want to know how to create a CLI install for the VCSA, I wrote a blog post about this topic a while ago.

CLI install VMware vCenter server 6.5

Almost on every project I have worked on, I make an kickstart script for installing VMware ESXi. Although at first, it seems a lot of work. Using a kickstart script for installing VMware ESXi has many advantages:

  • Every host is installed consistent.
  • Elimination of human installations errors.
  • Install script can be used as documentation.
  • In case of a re-installation (hardware failure for example), the host is installed quickly.
  • Every IT administrator can perform the installation, you don’t have to be a VMware Expert.
  • I have created kickstart scripts since ESXi version 4.

While reading the VMware vCenter 6.5 installation documentation, I saw the option for a vCenter Server CLI installation or upgrade. Again, performing an unattended installation of vCenter Server has the same advantage as an kickstart for ESXi.

As with everything, the first time, reading, testing, adjusting your script takes time. But it’s while worth it!

First something about the CLI installer.

NLVMUG 2018

This week, I had the opportunity to speak at the Dutch VMUG (NLVMUG) about a project I did last year.

Title of my session was: Migrate your datacenter without downtime

Session abstract
Moving a complete datacenter 50 KM, without downtime?
A few years ago this was unthinkable, but with the help of VMware techniques this is possible nowadays. In this customer case, Michael Wilmsen shows you how he did this for a university, using VMware techniques and PowerCLI. Not only the process of script development, but you will also get a better understanding of how the VMware techniques work and how they are applicable.
