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

03.10.2023 by William Lam // 8 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.

How to configure Hardware Compatibility List (HCL) database for vSphere Lifecycle Manager (vLCM) in an air-gapped environment?

12.01.2022 by William Lam // Leave a Comment

I was setting up another vSphere 8 environment in my homelab using my handy Automated vSphere & vSAN 8 Lab Deployment Script and I was reminded of another vSphere Lifecycle Manager (vLCM) question that I had received during VMware Explore Barcelona 2022.

The question was about configuring vCenter Server that would include full vLCM functionality in an air-gapped environment, where internet connectivity would not be available directly or in-directly through the use of a network proxy. Today, the VMware HCL database that is integrated with vLCM can only be synchronized when when your vCenter Server is connected to VMware's online repository when VMware's Customer Experience Improvement Program (CEIP) is enabled.


To synchronize the VMware HCL database using the vSphere UI, navigate to the vLCM administrator page and under Actions, select the Sync HCL operation, which will download the latest HCL database from VMware's online repo. You can also automate this using the vLCM REST API with the Update Compatibility Data Task API.

Here is a quick PowerCLI snippet performing the same operation but using the API instead:

Connect-CiSServer -Server vcsa.primp-industries.local -user administrator[at]vsphere[dot]local -Password VMware1!
$hclCompatDataService = Get-CisService -Name com.vmware.esx.hcl.compatibility_data
$hclLastUpdateOnline = $hclCompatDataService.get().updated_at

$hclCompatDataService.'update$task'()

However, for environments that can not connect to VMware's online repo, this poses a big operational challenge, especially for those looking to transition from vSphere Update Manager (VUM) to vLCM. For the vSAN HCL, we already provide a solution for air-gapped environments by providing an offline copy of the vSAN HCL database which detailed in VMware KB 2145116.

If a connected vCenter Server can download the VMware HCL that vLCM uses, I figure it should also be possible to replicate that behavior for an air-gapped environment? 🤔

How to automate checking for new vCenter Server updates in vSphere Lifecycle Manager (vLCM)?

11.27.2022 by William Lam // 2 Comments

A question that I had received during VMware Explore Barcelona, was how to automate the checking for new updates that are available for their vCenter Server? In the vSphere UI, when a new update is available and applicable, you will see a new blue label called Update Available under the Summary view when your vCenter Serve inventory object is selected.


When you click on the label, it will take you the vCenter Server Update Planner, a feature that was introduced back in vSphere 7, which is part of the overall vSphere Lifecycle Manager (vLCM) solution.


Here you will be shown a list of all applicable vCenter Server update(s) and/or upgrade(s) for your specific version of vCenter Server, including useful information like severity and even direct links to the release notes, which is extremely useful to quickly get a glance at a particular release.

As you might expect, all of the information displayed within the vSphere UI is available programmatically using the vCenter Server vLCM REST API, enabling users to periodically check when an update is available and create and run interoperability reports using the vCenter Server Update Planner feature.
