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.

Replacing disks in VSAN in the event of a disk failure


Computer hardware inevitably fails, and this will eventually be the case for the disks in your VSAN infrastructure. When a disk fails in VSAN, the data resident on this disk will be rebuilt elsewhere in the cluster and the cluster capacity will be reduced. Failed disks should then be replaced to recover the available capacity and restore full fault tolerance in the VSAN cluster.

Note

If you are removing and replacing healthy disks because you are performing an upgrade, please follow the Removing disks/disk groups from VSAN and Adding disks to VSAN recipes in this chapter.

Getting ready

You should be logged into vSphere Web Client as an administrator or a user authorized to make VSAN configuration changes.

The faulty disk should have been physically removed from the server and replaced with a healthy device.
