Create a Firmware Update Orchestration Strategy using Horizon

Use the Horizon Web interface as an alternative to the CLI for managing device /firmware image update strategies (Firmware update).

To use the CLI, see Device Image Update Orchestration.

To update device/firmware image Central Cloud’s RegionOne and the subclouds, you must create an update strategy for Distributed Cloud fw-update-strategy Orchestration.

About this task

Only one type of dcmanager strategy can exist at a time. The strategy controls how the subclouds are updated (for example, serially or in parallel).


You must be in the SystemController region. To change the mode, see RegionOne and SystemController Modes.


  1. Select the SystemController region.

  2. Select Distributed Cloud Admin > Orchestration.

  3. Select the Orchestration Strategy tab on the Orchestration page.

  4. Create a new strategy.

    Click Create Strategy. In the Create Strategy dialog box, adjust the settings as needed.

    Strategy Type


    Apply to

    Subcloud or Subcloud Group


    Enter the subcloud name

    Subcloud Group

    Enter the subcloud group name only if you select the Apply to: Subcloud Group option.

    Stop on Failure

    Default: True

    Determines whether update orchestration failure for a subcloud prevents application to subsequent subclouds.

    Subcloud Apply Type

    Parallel or Serial, default Parallel. Determines whether the subclouds are updated in parallel or serially.

    Maximum Parallel Subclouds

    Default: 20

    If this is not specified using the CLI, the values for max_parallel_subclouds defined for each subcloud group will be used by default.


    Default: False


    Create a strategy

  5. Adjust how device image nodes are updated on RegionOne and the subclouds.

  6. Save the new strategy.

    Click Create Strategy.


Only subclouds in the Managed state and whose patching sync status is out-of-sync are added to the list. To change the firmware upgrade strategy settings, you must delete the current strategy and create a new one. You must confirm before applying the strategy. If the created strategy is older than 60 minutes, a warning message will be displayed. You can simply apply the strategy or first verify that it is still valid.
