    .. caution::

        If you delete a subcloud, then you must reinstall it before you can
        re-add it.

    The **Host Details** menu selection for a subcloud switches to the Horizon
    Web interface for that subcloud. To switch back to the System Controller,
    use the subcloud or region selection menu at the top left of the Horizon
    window.

-   To show detailed information about subcloud ``install/bootstrap/deploy``
    failures, you select Distributed **Cloud Admin** > **Cloud Overview**.

    Then click on dropdown arrow. At the end you can get the subcloud error
    information.
