Once a cluster is configured to use images, it cannot be changed back to using baselines.

All ESXi hosts must be from the same vendor.

All ESXi hosts must be stateful (most boot from a disk).

All ESXi hosts must be version 7.0 or later.

There are few items to consider regarding the use of vSphere Lifecycle Manager images vs. This functionality allows you to take advantage of new functionalities, such as image recommendations, automated firmware updates, and hardware compatibility checks. Installation of Software and firmware updates happen simultaneously, using a single workflow. Images represent the desired state specification that includes software, drivers, and firmware to apply to all hosts in a cluster. vSphere Lifecycle Manager introduces a new method of maintaining all ESXi hosts in a cluster by defining an image for the cluster.

In previous releases of VMware Update Manager, virtual infrastructure administrators managed ESXi hosts using a combination of host patches, drivers, and ESXi OS images configured in update baselines and baseline groups.

Manging cluster software using desired state images.

vSphere Lifecycle Manager addresses this challenge by not only supporting the capabilities previously included in VMware Update Manager but also by introducing a new desired state model and by supporting updating of server firmware provided by the OEMs. With the introduction of hyper-converged features such as vSAN, ensuring that our server hardware is consistent and up to date is critical. While this has taken care of many of the functions required to maintain a virtual infrastructure, it ignored a critical aspect of that infrastructure, the server hardware. Traditionally, VMware Update Manager Server supported the installation of ESX/ESXi patches, upgrading ESX/ESXi versions, upgrading VMware Tools, and upgrading of VM hardware versions. Overview of WhatвЂ™s New in vSphere Lifecycle Manager In this post, I discuss the new features and how we can utilize them to simplify the management of your virtual infrastructure.

vSphere Lifecycle Manager introduces many new features that simplify the process of managing not only ESXi patching but also the full firmware lifecycle of the ESXi hostвЂ™s hardware. With the release of vSphere 7.0, VMware has not only added new functionality to the Update Manager Server but has rebranded this great tool as vSphere Lifecycle Manager (vLCM). However, the core functionality of Update Manager hasnвЂ™t changed much since the original 1.0 release. Since then, VMware has made numerous changes to Update Manager Server in some cases, introducing new features, while also removing features (guest operating system and application patching). This new solution was titled VMware Update Manager (VUM) Server. To simplify virtual infrastructure management, in 2007, VMware introduced a new feature with VMware VirtualCenter Server 2.5 that automated these processes.

This process included manually staging patch files as well as executing install and reboot commands to each ESX host.

We made it to Friday! And, believe it or not, it is about to be May 2022.In the early days of VMware ESX and VirtualCenter Server (now called vCenter Server), patching and upgrading ESX hosts was a manual and challenging task that required a significant amount of time from a virtual administrator to complete.
