The error 'resource is still in use' when removing a host from a vDS indicates active logical port assignments must be resolved before the host can be cleanly removed.
Question
An administrator is attempting to remove an ESXi 6.x host from a vSphere Distributed Switch (vDS). When the administrator attempts to remove the host, the following error is observed:
The resource '16' is still in use. What three steps are needed to successfully remove the host from the switch? (Choose three.)
Options
- ASelect Manage Ports on the vDS for the host.
- BLocate all ports currently in use on the vDS for the host.
- CMigrate or delete any vmkernel or virtual machine adapters associated with the switch.
- DRemove all network cards from the switch before trying to remove the host.
- ECreate a standard switch for everything to be automatically be migrated to.

Why each option
The error 'resource is still in use' when removing a host from a vDS indicates active logical port assignments must be resolved before the host can be cleanly removed.
Using Manage Ports on the vDS scoped to the specific host provides visibility into which logical ports are currently bound, which is the necessary starting point for resolving the error.
Locating all ports currently in use on the vDS for that host identifies the exact VMkernel adapters or VM port group connections that are holding the resource and triggering the error.
Migrating or deleting all VMkernel and virtual machine adapters associated with the vDS releases the port bindings, clears the resource-in-use condition, and allows the host removal to succeed.
Removing physical network cards (uplinks) from the vDS does not resolve a resource-in-use error, which is caused by logical port assignments such as VMkernel or VM adapters, not physical uplinks.
Creating a standard switch does not automatically migrate any adapters; migration must be performed manually, and simply adding a new switch does not release vDS port resources.
