You can remove a host from a cluster in a workload domain through the Workload Domains page in SDDC Manager UI.

When a host is removed, the vSAN members are reduced. Ensure that you have enough hosts remaining to facilitate the configured vSAN availability. Failure to do so might result in the datastore being marked as read-only or in data loss.

Prerequisites

If you are removing a host from an NSX-T workload cluster, delete any workload VMs created outside VMware Cloud Foundation or move them to another host.

Procedure

  1. On the SDDC Manager Dashboard, click Inventory > Workload Domains.
    The Workload Domains page displays information for all workload domains.
  2. In the workload domains table, click the name of the workload domain that you want to modify.
    The detail page for the selected workload domain appears.
  3. Click the Clusters tab.
  4. Click the name of the cluster from which you want to remove a host.
  5. Click the Hosts tab.
  6. Select the host to remove and click Remove Selected Hosts.
    An alert appears, asking you to confirm or cancel the action. If the removal results in the number of hosts in the cluster being less than the minimum number of required hosts, you must click Force Remove to remove the host.
  7. Click Remove to confirm the action.
    The details page for the cluster appears with a message indicating that the host is being removed. When the removal process is complete, the host is removed from the hosts table.

Results

The host is removed from the workload domain and added to the free pool.

What to do next

Clean up the host so that you can use it again. See Clean up a Decommissioned Host Using the Direct Console User Interface.
