Learning PowerCLI - Second Edition

By: Robert van den Nieuwendijk

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.

Creating calculated properties

You can use the Select-Object cmdlet to select certain properties of the objects that you want to return. For example, you can use the following code to return the name and the used space, in GB, of your virtual machines:

PowerCLI C:\> Get-VM | Select-Object -Property Name,UsedSpaceGB

But what if you want to return the used space in MB? The PowerCLI VirtualMachineImpl object has no UsedSpaceMB property. This is where you can use a calculated property. A calculated property is a PowerShell hash table with two elements: Name and Expression. The Name element contains the name that you want to give the calculated property. The Expression element contains a scriptblock with PowerCLI code to calculate the value of the property. To return the name and the used space in MB for all your virtual machines, run the following command:

PowerCLI C:\> Get-VM |
>> Select-Object -Property Name,
>> @{Name="UsedSpaceMB";Expression={1KB*$_.UsedSpaceGB}}
>&gt...
