When you no longer need a fault domain, you can remove it from the vSAN cluster.

Procedure

  1. Navigate to the vSAN cluster in the vSphere Web Client.
  2. Click the Configure tab.
  3. Under vSAN, click Fault Domains and Stretched Cluster.
  4. Select the fault domain that you want to delete and click the Remove selected fault domains icon ().
  5. Click Yes.

    All hosts in the fault domain are removed and the selected fault domain is deleted from the vSAN cluster. Each host that is not part of a fault domain is considered to reside in its own single-host fault domain.
