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 and the maximum number of decommission hosts tasks that you can run in parallel..


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. Activate or deactivate Skip failed hosts during decommissioning.
    This setting is enabled by default. When enabled, hosts that fail are skipped and decommissioning continues on the remaining hosts.
  6. Click Confirm.

What to do next

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