When you no longer need a fault domain, you can remove it from the Virtual SAN cluster.
Procedure
- Navigate to the Virtual SAN cluster in the vSphere Web Client.
- Click the Configure tab.
- Under vSAN, click Fault Domains and Stretched Cluster.
- Select the fault domain that you want to delete and click the Remove selected fault domains icon ().
- Click Yes.
All hosts in the fault domain are removed and the selected fault domain is deleted from the Virtual SAN cluster. Each host that is not part of a fault domain is considered to reside in its own single-host fault domain.
