The following document mentions that we support RAID (hw and sw) which is still unsupported.

https://docs.openshift.com/container-platform/4.11/post_installation_configuration/bare-metal-configuration.html#the-baremetalhost-spec

https://docs.openshift.com/container-platform/4.11/rest_api/provisioning_apis/provisioning-apis-index.html

We have a note in another section saying we don't support it outside of Fujitsu:

https://docs.openshift.com/container-platform/4.11/installing/installing_bare_metal_ipi/ipi-install-installation-workflow.html#configuring-the-raid_ipi-install-installation-workflow

Users can assume this is supported based on the above docs, could we add a note saying this isn't supported?
