In this case, delete the host key entry, if present, from ``/root/.ssh/known_hosts`` on the System Controller before doing reinstallations. .. rubric:: |prereq| .. _installing-a-subcloud-using-redfish-platform-management-service-ul-g5j-3f3-qjb: - The docker **rvmc** image needs to be added to the System Controller bootstrap override file, docker.io/starlingx/rvmc:|v_starlingx-rvmc|. - A new system CLI option ``--active`` is added to the :command:`load-import` command to allow the import into the System Controller ``/opt/dc-vault/loads``. The purpose of this is to allow Redfish install of subclouds referencing a single full copy of the ``bootimage.iso`` at ``/opt/dc-vault/loads``. \(Previously, the full ``bootimage.iso`` was duplicated for each :command:`subcloud add` command\). .. note:: This is required only once and does not have to be done for every subcloud install. :command:`dcmanager` recognizes bootimage names ending in <.iso> and <.sig> For example, .. parsed-literal:: ~(keystone_admin)]$ system --os-region-name SystemController load-import --active |installer-image-name|.iso |installer-image-name|.sig In order to be able to deploy subclouds from either controller, all local files that are referenced in the ``bootstrap.yml`` file must exist on both controllers (for example, ``/home/sysadmin/docker-registry-ca-cert.pem``). .. Greg updates required for -High Security Vulnerability Document Updates .. _increase-subcloud-platform-backup-size: ---------------------------------------------------- Increase Subcloud Platform Backup Size using the CLI ---------------------------------------------------- By default, 30GB is allocated for ``/opt/platform-backup``. If additional persistent disk space is required, the partition can be increased in the next subcloud reinstall using the following commands: - To increase ``/opt/platform-backup`` to 40GB, add the **persistent_size: 40000** parameter to the subcloud install-values.yaml file. - Use the :command:`dcmanager subcloud update` command to save the configuration change for the next subcloud reinstall. .. code-block:: none ~(keystone_admin)]$ dcmanager subcloud update --install-values For a new subcloud deployment, use the :command:`dcmanager subcloud add` command with the ``install-values.yaml`` file containing the desired ``persistent_size`` value. .. rubric:: |proc| #. At the subcloud location, physically install the servers and network connectivity required for the subcloud. .. note:: Do not power off the servers. The host portion of the server can be powered off, but the |BMC| portion of the server must be powered and accessible from the System Controller. There is no need to wipe the disks. .. note:: The servers require connectivity to a gateway router that provides IP routing between the subcloud management subnet and the System Controller management subnet, and between the subcloud |OAM| subnet and the System Controller subnet. .. include:: /_includes/installing-a-subcloud-using-redfish-platform-management-service.rest :start-after: begin-ref-1 :end-before: end-ref-1 #. Create the ``install-values.yaml`` file and use the content to pass the file into the :command:`dcmanager subcloud add` command, using the ``--install-values`` command option. .. note:: If your controller is on a ZTSystems Triton server that requires a longer timeout value, you can now use the ``rd.net.timeout.ipv6dad`` dracut parameter to specify an increased timeout value for dracut to wait for the interface to have carrier, and complete IPv6 duplicate address detection |DAD|. For the ZTSystems server, this can take more than four minutes. It is recommended to set this value to 300 seconds, by specifying the following in the ``subcloud install-values.yaml`` file: .. code-block:: none rd.net.timeout.ipv6dad: 300 .. note:: The ``wait_for_timeout`` value must be chosen based on your network performance (bandwidth, latency, and quality) and should be increased if the network does not meet the minimum or timeout requirements. The default value of 3600 seconds is based on a network bandwidth of 100 Mbps with a 50 ms delay. .. include:: /_includes/installing-a-subcloud-using-redfish-platform-management-service.rest :start-after: begin-syslimit :end-before: end-syslimit For example, :command:`--install-values /home/sysadmin/install-values.yaml`. .. parsed-literal:: # Specify the |prod| software version, for example 'nn.nn' for the |prod| nn.nn release of software. software_version: bootstrap_interface: # e.g. eno1 bootstrap_address: # e.g.128.224.151.183 bootstrap_address_prefix: # e.g. 23 # Board Management Controller bmc_address: # e.g. 128.224.64.180 bmc_username: # e.g. root # If the subcloud's bootstrap IP interface and the system controller are not on the # same network then the customer must configure a default route or static route # so that the Central Cloud can login bootstrap the newly installed subcloud. # If nexthop_gateway is specified and the network_address is not specified then a # default route will be configured.

If there is a deployment failure, do not delete the subcloud, use the :command:`subcloud reconfig` command, to reconfigure the subcloud. For more information, see :ref:`Managing Subclouds Using the CLI `. #.
