Depending on your requirement, you can move hosts out of a fault domain.
Verify that the host is online. You cannot move hosts that are offline or unavailable from a fault domain.
- Navigate to the vSAN cluster.
- Click the Configure tab.
- Under vSAN, click Fault Domains.
Expand an existing fault domain to view its member hosts.
Select the host that you want to move and click the Move hosts out of fault domain icon. You also can click and drag the host out of the fault domain.
vSphere Web Client
Select the host that you want to move and click the Move hosts out of fault domain icon.
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 Host into Selected Fault Domain.
