Removing hosts from the Cloud Foundation inventory is called decommissioning. You can decommission a host for maintenance work or if you want to add it to another network pool. If you want to re-use a host in a different workload domain, you must decommission the host and clean it up before adding it to the workload domain.
Prerequisites
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 Cluster in a Workload Domain.
Procedure
What to do next
Clean the decommissioned host before adding it to a workload domain. See Cleaning Up Decommissioned Hosts.
