You can delete a VI workload domain from the SDDC Manager Dashboard.

When you delete a workload domain, the clusters within that workload domain are deleted and the hosts are returned to the free pool.

Deleting a VI workload domain also removes the components associated with the workload domain from the management domain. This includes the vCenter Server instance and the NSX Manager cluster.
Note: If the NSX Manager cluster is shared with any other VI workload domains, it cannot be deleted.

The network pools used by the workload domain are not deleted as part of the workload domain deletion process and must be deleted separately.

Caution: Deleting a workload domain is an irreversible operation. All clusters and VMs within the workload domain are deleted and the underlying datastores are destroyed.
It can take up to 20 minutes for a workload domain to be deleted. During this process, you cannot perform any operations on workload domains.

Prerequisites

  • If remote vSAN datastores are mounted on a cluster in the workload domain, the workload domain cannot be deleted. To delete such workload domains, you must first migrate any VMs from the remote datastore to the local datastore and then unmount the remote vSAN datastores from vCenter Server.
  • Back up the data on the workload domain. The datastores on the workload domain are destroyed when the workload domain is deleted.
  • Migrate the VMs that you want to keep to another workload domain.
  • Delete any workload VMs created outside VMware Cloud Foundation before deleting the workload domain.
  • Delete any NSX Edge clusters hosted on the workload domain. See KB 78635.

Procedure

  1. On the SDDC Manager Dashboard, click Inventory > Workload Domains.
    The Workload Domains page displays information for all workload domains.
  2. Click the vertical ellipsis (three dots) next to the workload domain you want to remove and click Delete Domain.
    A confirmation window appears with details about the impact of deleting the workload domain, including how many hosts will be returned to the free pool.
  3. On the Delete Workload Domain dialog box, click Delete Workload Domain.
    The details page for the workload domain appears with a message indicating that the workload domain is being deleted. When the removal process is complete, the workload domain is removed from the domains table.
