If your location is RHCOS enabled, then you can attach hosts that are running either RHEL and RHCOS. If your location isn't RHCOS enabled, then you can attach only hosts that are running RHEL. You can check whether your [location is RHCOS enabled](https://cloud.ibm.com/docs/satellite?topic=satellite-locations&format=markdown#verify-coreos-location). For more information about operating system support, see [Planning your operating system](https://cloud.ibm.com/docs/satellite?topic=satellite-infrastructure-plan&format=markdown#infras-plan-os). You can verify your host setup with the `satellite-host-check` script.
