Update Orchestration of Subclouds

You can use update orchestration to automate software updates across all subclouds in the .

You can use the Horizon Web interface or the CLI. To use the CLI, see update-orchestration-of-central-clouds-regionone-and-subclouds-using-the-cli.

Note

Patch orchestration is the recommended method for updating software on a system. Do not update individual subclouds manually.

To use update orchestration, complete the following workflow:

  1. Ensure that the required updates are uploaded and applied to the SystemController / central update repository.

    For more information, see uploading-and-applying-updates-to-systemcontroller-using-horizon.

  2. Update the RegionOne, for more information see uploading-and-applying-updates-to-systemcontroller-using-horizon-update-the-regionone.

  3. Create an update strategy for the update orchestration.

    See creating-an-update-strategy-for-distributed-cloud-update-orchestration.

  4. Optionally, customize the configuration settings used by the update strategy.

    The update strategy is applied to all subclouds using default configuration settings. You can change these settings, and you can create custom settings for individual subclouds. For more information, see customizing-the-update-configuration-for-distributed-cloud-update-orchestration.

  5. Apply the strategy for the update orchestration.

    See applying-the-update-strategy-for-distributed-cloud.

    As each subcloud is updated, it moves through the following states:

    initial

    The update has not started.

    pre-check

    Subcloud alarm status is being checked for management-affecting alarms.

    updating patches

    Patches are being updated to synchronize with System Controller updates.

    creating strategy

    The strategy is being created in the subcloud.

    applying strategy

    The strategy is being applied in the subcloud.

    finishing

    Updates that are no longer required are being deleted.

    Updates that require committing are being committed.

    complete

    Updating has been completed successfully.

    During this process, alarms 900.001 and 900.101 are raised temporarily.
