How to automate adding a license into vCenter Server with custom label? 

by // Leave a Comment

When adding a license key into vCenter Server using the vSphere UI, users have the ability to provide a custom label that is then associated with that specific license key.


This is certainly more useful than the system default label which uses "License N", where N is an incrementing number.

While the majority of license management can be fully automated using the vCenter Server LicenseManager API, adding a license key with a custom label is unfourntately an operation that is currently not possible with the public API.

With that said, there is a way in which you can still automate this operation 🙂

Automated ESXi Installation with a USB Network Adapter using Kickstart

by // 4 Comments

I have been working with the Project Keswick team for quite some time now, which is an OCTO project is lead by my good friend Alan Renouf, who is doing some really innovative work with ESXi at the edge and application deployment using a desired state engine.

Recently I had met with the team to discuss some of the options for their automated deployment which uses the tried and true ESXi scripted installation aka ESXi Kickstart. One thing that I had shared was just how powerful the %pre section within the kickstart is and can be used to redefine or update the original kickstart based on your installation criteria. For example, you could pull down external configuration files and determine at runtime to decide how you want to configure your networking to even fully bootstrapping a local vSAN datastore and this would all happen prior to ESXi installer starting. I have used the %pre section numerous times as a customer and also demonstrated in my USB-to-SDDC project which has also been an inspiration for the Project Keswick team.

One very cool capability that Project Keswick is enabling is the integration of the popular USB Network Native Driver for ESXi and one challenge they had faced with automating an ESXi installation when only a USB network adapter was available is additional configuration that must be setup before the installer can begin. They shared their solution and thought this would be a good blog post topic, especially as I know many folks use the USB Network Native Driver for ESXi in their homelab and if you wish to automate the installation, the solution shared from the team could help.

How to bootstrap ESXi compute only node and connect to vSAN HCI Mesh?

by // Leave a Comment

After documenting the process for bootstrapping vSAN Express Storage Architecture (ESA) using my Intel NUC 12 Pro, I was looking for an easier way to share my physical vSAN storage, which is powered by a single Supermicro E200-8D, to other physical ESXi hosts for testing purposes.

I had recently been playing with the vSAN HCI Mesh feature, which was launched back in 2020, as I was running out of spare NVMe devices when needing to test different physical hardware kits. While my use case for the storage is typically short lived, it means I do not have to play musical chairs with the limited number of NVMe devices I have installed in the various kits I have.

The vSphere UI in vCenter Server already provides a very simple workflow to mount a remote vSAN storage on an ESXi compute-only node, but I was also looking at this from a bootstrapping point of view and what if vCenter Server was not deployed or even available? Could I still make this work? After a bit of trial and error, I was able to figure out this can be accomplished by using a series of ESXCLI commands!
