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.
