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 in the vSphere Web Client.
- Click the Configure tab.
- Under vSAN, click Fault Domains and Stretched Cluster.
- Select the host that you want to move and click the Move hosts out of fault domain icon ().
- 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.
