Depending on your requirement, you can move hosts out of a fault domain.

Prerequisites

Verify that the host is online. You cannot move hosts that are offline or unavailable from a fault domain.

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 host that you want to move and click the Move hosts out of fault domain icon ().
  5. Click Yes.

    The selected host is no longer part of the fault domain. Any host that is not part of a fault domain is considered to reside in its own single-host fault domain.

What to do next

You can add hosts to fault domains. See Move Hosts into an Existing Fault Domain.
