VMware vSphere Lifecycle Manager (vLCM) is a powerful tool integrated within vCenter Server that simplifies and automates the lifecycle management of ESXi hosts across a datacenter. With vLCM, administrators can deploy consistent software images, maintain patch levels, manage firmware compliance, and streamline infrastructure updates all in one place.

Whether you’re managing a few hosts or hundreds across multiple clusters, vLCM ensures your environment stays secure, up-to-date, and compliant with your hardware and vendor standards.

In this blog post, we’ll explore what vSphere Lifecycle Manager is, how it works, its benefits, and how you can use it to streamline the management of your vSphere environment.

What is vSphere Lifecycle Manager?

vSphere Lifecycle Manager (vLCM) is a tool built into VMware vSphere, starting from version 7.0, that simplifies the management of the lifecycle of ESXi hosts. It provides an automated and declarative approach to managing the configuration and firmware of ESXi hosts, ensuring consistency across your entire infrastructure.

Before vLCM, managing ESXi hosts and maintaining their updates, configurations, and compatibility required multiple separate tools and manual processes. With vLCM, VMware has integrated these functions into a single, centralized management tool.

vLCM is designed to:

• Automate the patching and updating of ESXi hosts.
• Manage host image and hardware baselines (drivers, firmware, etc.).
• Ensure consistency across clusters.
• Improve the compliance and security of your infrastructure.
• Reduce downtime and manual intervention in lifecycle tasks.

What is vSphere Lifecycle Manager Used For

vSphere Lifecycle Manager (vLCM) is primarily used to streamline and automate the management of ESXi host lifecycles within a vSphere environment. It enables administrators to upgrade ESXi hosts to newer versions and apply critical patches and security updates efficiently. One of its core strengths is maintaining consistency across clusters by enforcing a standardized image profile for all hosts, ensuring uniformity in versions, drivers, and firmware. Additionally, vLCM allows seamless integration of vendor-specific firmware and driver add-ons, enhancing compatibility with OEM hardware such as Dell, HPE, or Cisco Systems. It supports the validation of hardware compatibility through VMware’s Hardware Compatibility List (HCL), preventing unsupported configurations. vLCM also provides capabilities to import and manage custom ISO images, making it flexible for environments that require offline updates or tailored deployment media. Moreover, it facilitates the application of host baselines for patching and compliance, helping administrators maintain a secure and up-to-date virtual infrastructure.

Key Sections of vSphere Lifecycle Manager Explained

Let’s break down the major components you’ll work with inside the vLCM interface

Image Depot

The Image Depot is a central repository within vSphere Lifecycle Manager (vLCM) that houses all the essential components needed to build and maintain ESXi host images. It stores ESXi base images at the ISO level, which serve as the foundational OS for your hosts. Additionally, it contains vendor-specific addons provided by hardware manufacturers like Dell, HPE, or Cisco, ensuring compatibility with server firmware and drivers. The depot also includes individual firmware and driver components, allowing for granular customization of host images. Patch updates released by VMware are stored here as well, making it easy to keep your environment secure and up to date.

ESXi Versions

The ESXi Versions section within vSphere Lifecycle Manager displays the available base ESXi images that serve as the core operating system for your hosts. These images are essential for deploying new hosts or upgrading existing ones. Within this tab, administrators can view the ESXi versions currently in use across the environment, add newer versions to the image depot for future upgrades, and compare these versions against the hardware compatibility list to ensure they meet the requirements of your specific infrastructure. This makes it easier to plan upgrades confidently, avoiding any potential incompatibilities or unsupported configurations.

Vendor Addons

Vendor addons provide custom firmware and driver packages from hardware vendors like:

• Dell EMC (OMIVV)
• HPE (iLO Amplifier)
• Cisco UCS

These ensure optimal compatibility and performance with OEM hardware.

Components

These are granular packages like NIC drivers, HBA firmware, and other vendor-specific hardware modules. You can customize the image by adding or removing components.

Updates

The Updates section includes all available patches, bug fixes, and security updates released by VMware. From here, you can create custom baselines and remediate your infrastructure.

Sync Updates

This feature allows you to synchronize the latest updates from VMware’s public repositories to ensure your depot is always up to date.

Note: Requires internet access or a configured proxy.

Import Updates

You can manually import ZIP bundles or ISOs when your vCenter doesn’t have internet access. This supports offline patching scenarios, which are common in air-gapped environments.

Hardware Compatibility List (HCL)

vLCM validates your host firmware and drivers against the VMware Compatibility Guide (VCG) or HCL database. This helps:

• Prevent unsupported upgrades
• Identify hardware inconsistencies
• Maintain stability

Imported ISOs

Here, you can upload and manage custom ESXi ISOs, which might include pre-configured drivers or OEM customizations. Useful in custom deployments.

Baselines

Still available for backward compatibility, baselines are used to define patch and upgrade rules for:

• Security updates
• Bug fixes
• Host upgrades

Note: VMware recommends switching to the Image-based model in vSphere 7 and later.

Settings

This section lets you configure:

• Patch Download Sources (online/offline)
• Proxy Settings
• Scheduled Tasks
• Update Behavior

Settings help customize how Lifecycle Manager operates within your environment.

When to Use Image-Based vs. Baseline-Based Lifecycle Management

vSphere Lifecycle Manager supports two primary approaches to host lifecycle management:

Image-Based and Baseline-Based. Choosing the right model depends on your infrastructure setup and long-term strategy. The Image-Based model is best suited for environments where consistency is critical particularly when managing clusters built on standardized OEM hardware such as Dell, HPE, or Cisco.

On the other hand, the Baseline-Based model is better suited for managing standalone hosts, mixed hardware environments, or during transitional phases where legacy systems still rely on vSphere Update Manager (VUM).

Model	Use When…
Image-Based	Managing consistent clusters with OEM hardware
Baseline-Based	Managing standalone hosts or transitioning from VUM

VMware recommends image-based lifecycle for all modern environments running vSphere 7 and above.

vSphere Lifecycle Manager (vLCM) Tutorial

In the following lab tutorial, we will walk through how to use vSphere Lifecycle Manager (vLCM) to manage the lifecycle of ESXi hosts in a vSphere environment. This includes creating and managing host images, patching, upgrading, and managing hardware baselines.

Prerequisites:
