Overview of this book

VMware vSphere PowerCLI, a free extension to Microsoft Windows PowerShell, enables you to automate the management of a VMware vSphere or vCloud environment. This book will show you how to automate your tasks and make your job easier. Starting with an introduction to the basics of PowerCLI, the book will teach you how to manage your vSphere and vCloud infrastructure from the command line. To help you manage a vSphere host overall, you will learn how to manage vSphere ESXi hosts, host profiles, host services, host firewall, and deploy and upgrade ESXi hosts using Image Builder and Auto Deploy. The next chapter will not only teach you how to create datastore and datastore clusters, but you’ll also work with profile-driven and policy-based storage to manage your storage. To create a disaster recovery solution and retrieve information from vRealize Operations, you will learn how to use Site Recovery Manager and vRealize Operations respectively. Towards the end, you’ll see how to use the REST APIs from PowerShell to manage NSX and vRealize Automation and create patch baselines, scan hosts against the baselines for missing patches, and re-mediate hosts. By the end of the book, you will be capable of using the best tool to automate the management and configuration of VMware vSphere.

Preface

Chapter 10. Patching ESXi Hosts and Upgrading Virtual Machines

You have to keep your ESXi hosts up to date with the latest patches to keep them secure and to solve bugs. The hardware compatibility of the virtual machines and the version of the VMware Tools in your virtual machines have to be updated as well to be able to use the newest features. All of these updates can be done and managed using the VMware vSphere Update Manager (VUM). This powerful piece of software is included in the VMware vCenter Server license.

vSphere Update Manager uses a local repository in which it stores patches downloaded from VMware and VMware partners, such as Dell and Hewlett Packard Enterprise (HPE). You can create baselines, in which you define the patches that have to be installed on your hosts. Then, you can scan your hosts for compliance with the baselines. If a host has missing patches, you can stage the missing patches to the host. Finally, you can remediate your hosts to install the missing patches....
