Overview of this book

VMware Virtual SAN is a radically simple, hypervisor-converged storage, designed and optimized for vSphere virtual infrastructure. VMware introduced the software to help customers store more and more virtual machines. As data centers continue to evolve and grow, managing infrastructure becomes more challenging. Traditional storage solutions like monolithic storage arrays and complex management are often ill-suited to the needs of the modern data center. Software-defined storage solutions, like VMware Virtual SAN, integrate the storage side of the infrastructure with the server side, and can simplify management and improve flexibility. This book is a detailed guide which provides you with the knowledge you need to successfully implement and manage VMware VSAN and deployed infrastructures. You will start with an introduction to VSAN and object storage, before moving on to hardware selection, critical to a successful VSAN deployment. Next, you will discover how to prepare your existing infrastructure to support your VSAN deployment and explore Storage policy-Based Management, including policy changes, maintenance, validation, and troubleshooting VSAN. Finally, the book provides recipes to expedite the resolution process and gather all the information required to pursue a rapid resolution.

Removing disks/disk groups from VSAN


At some point during the course of your production and development with VSAN, you may wish to remove disks or disk groups from VSAN usage. For example, you may wish to upgrade your existing disks or otherwise repurpose them if VSAN is not capacity or performance constrained. While this process will probably be less common than adding capacity to VSAN, these operations can be executed via vSphere Web Client.

Tip

If you are using vSphere 5.5, it is strongly recommended that you first place the host into maintenance mode by selecting the Ensure accessibility or Full data migration option.

Getting ready

You should be logged into vSphere Web Client as an administrator or a user authorized to alter VSAN configurations.

Note

To remove disks or disk groups, the VSAN cluster must not be in the auto-claim mode. If you need to change your auto-claim settings, please begin with Disable auto-claim mode. If you do not use the auto-claim mode, you may skip this section.
