You can remove a host from a vSphere cluster in the management domain or a VI workload domain through the Workload Domains page in the SDDC Manager Dashboard.

Before you remove a host from a vSphere cluster, 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

  • Delete any workload VMs created outside VMware Cloud Foundation or move them to another host.
  • You cannot remove a host from a vSphere cluster if that vSphere cluster is hosting an Edge node.
    • Move the Edge node to another host in the same vSphere cluster. You cannot move an Edge node to a host that already hosts another Edge node.
    • If you cannot move the Edge node, delete the Edge node on the host. You cannot delete Edge nodes if doing so would result in an Edge cluster with fewer than two Edge nodes.
  • You cannot remove a host from a vSphere cluster if that vSphere cluster was selected for Edge node placement and the Edge node deployment is still in pending state.

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

Re-image the host so that you can use it again.
