Is my vSphere Cluster managed by vSphere Lifecycle Manager (vLCM) as a Desired Image or Baseline?

03.10.2023 by William Lam // 11 Comments

Prior to vSphere 7.0, ESXi lifecycle management has been provided by vSphere Update Manager (VUM), which has been around for more than a decade plus and is most likely what you are still using today. With the release of vSphere 7.0, VMware introduced a brand new lifecycle management solution for ESXi called vSphere Lifecycle Manager (vLCM), which you can read more about HERE.


While VMware has made it clear that vLCM will be the future going forward for ESXi lifecycle management, we also understand that most customers will still be using the existing VUM-based solution and we wanted to make sure it was easy to  transition between the two solutions, especially within the vSphere UI.

An interesting question was recently brought up was how to determine whether a vSphere Cluster was using the new vLCM solution based on desired images versus VUM, which uses baselines?

Note: If you are not familiar between vLCM Desired Image and VUM Baselines, be sure to check out this helpful resource HERE.

VUM UMDS Docker Container for vSphere 6.5

12.07.2016 by William Lam // Leave a Comment

Early last week, I had published an article on how to automate the deployment of VUM's Update Manager Download Service (UMDS) in vSphere 6.5 for an Ubuntu 14.04 distribution. The interesting backstory to that script is that it started from a Docker Container that I had initially built for the VUM UMDS. I found that being able to quickly spin up UMDS instance using a Docker Container purely from a testing standpoint was much easier than needing to deploy a full VM, especially as I have Docker running on my desktop machines. Obviously, there are limitations with using a Docker Container, especially if you plan to use UMDS for a longer duration and need persistence. However, for quick lab purposes, it may just fit the bill and even with Docker Containers, you can use Docker Volumes to help persist the downloaded content.

You can find the Dockerfile and its respective scripts on my Github repo here: https://github.com/lamw/vum-umds-docker

Below are the instructions on how to use the VUM UMDS Docker Container.

Automating the installation of VUM Update Manager Download Service (UMDS) for Linux in vSphere 6.5

11.28.2016 by William Lam // 10 Comments

One of the most highly requested feature from customers with regards to the adoption of the vCenter Server Appliance (VCSA) is to have vSphere Update Manager (VUM) available as a Virtual Appliance. With the vSphere 6.5 release, this is now a reality as VUM is now embedded within the VCSA. The VUM service is also automatically enabled and associated with the vCenter Server instance which means from a customer standpoint, it is zero touch to get VUM up and running!

In addition to VUM being part of the VCSA 6.5, there is also the VUM Update Manager Download Service (UMDS) that can be installed on a separate Linux system. You can find the UMDS installer within the VCSA 6.5 ISO under the umds directory. To install UMDS, there are several pre-requisites that you must meet, some of which are documented here. The other requirements which are not documented are the additional OS package dependencies required to run the UMDS installer. While going through this by hand the first time, I found the following packages were required to install on an Ubuntu 14.04 distribution:

  • perl
  • tar
  • sed
  • psmisc
  • unixodbc
  • postgresql
  • postgresql-contrib
  • odbc-postgresql

For those of you who know me, if I have to perform something manually once, I might as well automate it for the future 🙂 I decided to create this quick shell script called install_umds65.sh which will allow you to easily deploy UMDS on an Ubuntu LTS 14.04 distribution. This can be useful for automated deployments or quickly standing up a lab environment.
