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.

Upgrading datastores to VMFS-5

With vSphere 5, VMware upgraded the VMFS file system to version 5. VMFS-5 came with the following new features:

  • Unified 1 MB file block size

  • Large single extent volumes of 64 TB

  • Smaller 8 KB sub-block

  • Small file support

  • Increased file count limit greater than 120,000

  • VMware vSphere Storage APIs for Array Integration (VAAI)

  • Primitive Atomic Test & Set (ATS)

  • Enhancement for file locking

  • GUID Partition Table (GPT)

  • A new starting sector of 2048

If you upgraded your vSphere environment from version 4 or earlier to version 5 or 6, your datastores are probably still on VMFS-3. There are two options for going to VMFS-5. The first option is to create new VMFS-5 datastores and move your virtual machines to the new datastores. When your old VMFS-3 datastores are empty, you can remove them. The advantage of this method is that the new datastores will have all of the new VMFS-5 features. However, it is a lot of work, and you need enough free space on your storage system to create...
