## Uninstall Trilio components in RHOSP16

To uninstall the Trilio components, you need modify the deploy command and update the cloud using the new command.

Remove the trilio\_env\_osp16.yaml and roles\_data.yaml from overcloud deploy command and then run it. After the changes the overcloud deployment command will look like this:

```
openstack overcloud deploy --templates \
--libvirt-type qemu \
--ntp-server 192.168.1.34 \
-e /home/stack/templates/node-info.yaml \
-e /home/stack/containers-prepare-parameter.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/ssl/enable-tls.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/ssl/inject-trust-anchor.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/ssl/tls-endpoints-public-ip.yaml
```
