Removing hosts from the SDDC Manager inventory is called decommissioning. If you want to re-use a host in a different workload domain, you must decommission, re-image, and commission the host before adding it to the workload domain.

See VMware Configuration Maximums for information about the maximum number of hosts you can decommission at one time.


The hosts that you want to decommission must not be assigned to a workload domain. If a host is assigned to a workload domain, you must remove it before you can decommission it. See Remove a Host from a vSphere Cluster in a Workload Domain.


  1. In the navigation pane, click Inventory > Hosts.
  2. Click Unassigned Hosts.
  3. In the hosts table, select the host(s) you want to decommission.
  4. Click Decommission Selected Hosts.
  5. Click Confirm.

What to do next

Re-image the decommissioned host before commissioning it again and adding it to a workload domain.
