The system controller can be upgraded using either a manual software upgrade procedure or by using the non-distributed systems :command:`sw-manager` orchestration procedure. .. rubric:: |context| Follow the steps below to manually upgrade the system controller: .. rubric:: |prereq| - Validate the list of new images with the target release. If you are using a private registry for installs/upgrades, you must populate your private registry with the new images prior to bootstrap and/or patch application. .. rubric:: |proc| .. _upgrading-the-systemcontroller-using-the-cli-steps-oq4-dgm-cmb: #.

Transfer iso and signature files to controller-0 (active controller) and import the load. .. code-block:: none ~(keystone_admin)]$ system --os-region-name SystemController load-import --local .iso .sig .. note:: Move the iso to ``/opt/backups`` before importing the load to avoid any disk space issues during the load import. .. note:: If you face any issue while importing the load, go to ``/var/log/load-import.log`` and examine the error messages. .. note:: This can take several minutes. After the system controller is successfully upgraded, the old load (which is in imported state) should not be deleted from load list otherwise the subcloud upgrade orchestration will fail with an error. #. Apply any required software updates. After the update is installed ensure controller-0 is active. The system controller as well as the subclouds must be 'patch current'. All software updates related to your current |prod| software release must be uploaded, applied, and installed. All software updates to the new |prod| release, only need to be uploaded and applied. The install of these software updates will occur automatically during the software upgrade procedure as the hosts are reset to load the new release of software. .. only:: partner .. include:: /_includes/upgrading-the-systemcontroller-using-the-cli.rest :start-after: wrsbegin :end-before: wrsend For more information, see |updates-doc|: :ref:`Managing Software Updates `. #. Confirm that the system is healthy.

It is strongly recommended that you clear your system of all alarms before doing an upgrade. .. note:: Use the command :command:`system upgrade-start --force` to force the upgrade process to start and ignore non-management-affecting alarms. This should ONLY be done if these alarms do not cause an issue for the upgrades process. #. Start the upgrade from controller-0.

Configuration changes must not be made after this point, until the upgrade is completed. The following upgrade state applies once this command is executed. Run the :command:`system upgrade-show` command to verify the status of the upgrade. - started: - State entered after :command:`system upgrade-start` completes. - Release system data (for example, postgres databases) has been exported to be used in the upgrade. As part of the upgrade, the upgrade process checks the health of the system and validates that the system is ready for an upgrade. The upgrade process checks that no alarms are active before starting an upgrade. .. note:: Use the command :command:`system upgrade-start --force` to force the upgrades process to start and to ignore management affecting alarms. This should only be done if these alarms do not cause an issue for the upgrades process. The ``fm alarm-list --mgmt_affecting`` option provides specific alarms which may be blocking an orchestrated upgrade. On systems with Ceph storage, it also checks that the Ceph cluster is healthy. #.
