=======================================================
Distributed Upgrade Orchestration Process Using the CLI
=======================================================

Distributed upgrade orchestration can be initiated after the System Controller
has been successfully upgraded.

.. rubric:: |context|

The user first creates a distributed upgrade orchestration strategy, or plan,
for the automated upgrade procedure. This customizes the upgrade orchestration,
using parameters to specify:


.. _distributed-upgrade-orchestration-process-using-the-cli-ul-eyw-fyr-31b:

-   whether to stop on failure of a subcloud upgrade or continue with the next
    subcloud

-   whether to upgrade hosts serially or in parallel


Based on these parameters, and the state of the subclouds, the upgrade
orchestration creates a number of stages for the overall upgrade strategy. All
the subclouds that are included in the same stage will be upgraded in parallel.

.. rubric:: |prereq|

Distributed upgrade orchestration can only be done on a system that meets the
following conditions:

.. _distributed-upgrade-orchestration-process-using-the-cli-ul-blp-gcx-ry:

-   The subclouds must use the Redfish platform management service if it is
    an |AIO-SX| subcloud.

-   Duplex \(|AIO-DX|/Standard\) upgrades are supported, and they do not
    require remote install using Redfish.

-   Redfish |BMC| is required for orchestrated subcloud upgrades. The install
    values, and :command:`bmc_password` for each |AIO-SX| subcloud controller
    must be provided using the following |CLI| command on the System Controller.

    .. note::
        This is only needed if the subcloud has not already been provisioned
        with the Redfish BMC password.

    .. code-block:: none

        ~(keystone_admin)]$ dcmanager subcloud update subcloud1 --install-values\
        install-values.yaml --bmc-password <password>

    For more information on :command:`install-values.yaml` file, see
    :ref:`Installing a Subcloud Using Redfish Platform Management Service
    <installing-a-subcloud-using-redfish-platform-management-service>`.

-   All subclouds are clear of management-affecting alarms \(with the exception of the alarm upgrade
    in progress\).

-   All hosts of all subclouds must be unlocked, enabled, and available.

-   No distributed upgrade orchestration strategy exists, to verify use the
    command :command:`dcmanager upgrade-strategy-show`. An upgrade cannot be
    orchestrated while upgrade orchestration is in progress.

-   Verify the size and format of the platform-backup filesystem on each
    subcloud. From the shell on each subcloud, use the following command to view
    the details of the file system:

    :command:`df -Th /opt/platform-backup`

    The type must be ext4 and the size must be 9.5GB. For example, on
    controller-0, run the following command:

    .. code-block:: none

        ~(keystone_admin)]$ df -Th /opt/platform-backup/ Filesystem Type Size Used Avail Use% Mounted on /dev/sda2 ext4 9.5G 51M 9.0G 1% /opt/platform-backup

-   **If a previous upgrade has been done on the subcloud**, from the shell on
    each subcloud, use the following command to remove the previous upgrade
    data:

    :command:`sudo rm /opt/platform-backup/upgrade_data\*`

.. rubric:: |proc|

.. _distributed-upgrade-orchestration-process-using-the-cli-steps-vcm-pq4-3mb:

#.  Review the upgrade status for the subclouds.

    After the System Controller upgrade is completed, wait for 10 minutes for
    the **load_sync_status** of all subclouds to be updated.

    To identify which subclouds are upgrade-current \(in-sync\), use the
    :command:`subcloud list` command. For example:

    .. code-block:: none

        ~(keystone_admin)]$ dcmanager subcloud list
        +----+-----------+--------------+--------------------+-------------+
        | id | name      | management   | availability       | sync        |
        +----+-----------+--------------+--------------------+-------------+
        |  1 | subcloud1 | managed      | online             | out-of-sync |
        |  2 | subcloud2 | managed      | online             | out-of-sync |
        |  3 | subcloud3 | managed      | online             | out-of-sync |
        |  4 | subcloud4 | managed      | online             | out-of-sync |
        +----+-----------+--------------+--------------------+-------------+

    .. note::
        The sync status is the rolled up sync status of platform, patching,
        identity, etc.

    To see synchronization details for a subcloud, use the following command:

    .. code-block:: none

        ~(keystone_admin)]$ dcmanager subcloud show subcloud1
        +-----------------------------+------------------------------+

#.  To create an upgrade strategy, use the :command:`dcmanager upgrade-strategy create`
    command.

    The upgrade strategy for a |prod-dc| system controls how upgrades are
    applied to subclouds.

    .. code-block:: none

        ~(keystone_admin)]$ dcmanager upgrade-strategy create \
        [--subcloud-apply-type <type>] \
        [–-max-parallel-subclouds <i>] \
        [–-stop-on-failure <level>] \
        [--group group] \
        [<subcloud>]

    where:

    **subcloud-apply-type**
        **parallel** or **serial**— determines whether the subclouds are
        upgraded in parallel, or serially.

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

    **max-parallel-subclouds**
        Sets the maximum number of subclouds that can be upgraded in parallel
        \(default 20\).

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

    **stop-on-failure**
        **true**\(default\) or **false**— determines whether upgrade
        orchestration failure for a subcloud prevents application to subsequent
        subclouds.

    **group**
        Optionally pass the name or ID of a subcloud group to the
        :command:`dcmanager upgrade-strategy create` command. This results in a
        strategy that is only applied to all subclouds in the specified group.
        The subcloud group values are used for subcloud apply type and max
        parallel subclouds parameters.

    For example:

    .. code-block:: none

        ~(keystone_admin)]$ dcmanager upgrade-strategy create
        +------------------------+----------------------------+
        | Field                  | Value                      |
        +------------------------+----------------------------+
        | strategy type          | upgrade                    |
        | subcloud apply type    | parallel                   |
        | max parallel subclouds | 10                         |
        | stop on failure        | False                      |
        | state                  | initial                    |
        | created_at             | 2020-06-10T17:16:51.857207 |
        | updated_at             | None                       |
        +------------------------+----------------------------+

#.  To show the settings for the upgrade strategy, use the
    :command:`dcmanager upgrade-strategy show` command.

    For example:

    .. code-block:: none

        ~(keystone_admin)]$ dcmanager upgrade-strategy show
        +------------------------+----------------------------+
        | Field                  | Value                      |
        +------------------------+----------------------------+
        | subcloud apply type    | parallel                   |
        | max parallel subclouds | 20                         |
        | stop on failure        | False                      |
        | state                  | initial                    |
        | created_at             | 2020-02-02T14:42:13.822499 |
        | updated_at             | None                       |
        +------------------------+----------------------------+

    .. note::
        The values for `subcloud apply type` and `max parallel subclouds` will
        be taken from the subcloud group if specified through the ``--group``
        parameter.

#.  Review the upgrade strategy for the subclouds.

    To show the subclouds that will be upgraded when the upgrade strategy is
    applied, use the :command:`dcmanager strategy-step list` command. For
    example:

    .. code-block:: none

        ~(keystone_admin)]$ dcmanager strategy-step list
        +------------------+-------+---------+---------+------------+-------------+
        | cloud            | stage | state   | details | started_at | finished_at |
        +------------------+-------+---------+---------+------------+-------------+
        | subcloud-1       |     1 | initial |         | None       | None        |
        | subcloud-4       |     1 | initial |         | None       | None        |
        | subcloud-5       |     2 | initial |         | None       | None        |
        | subcloud-6       |     2 | initial |         | None       | None        |
        +------------------+-------+---------+---------+------------+-------------+

    .. note::
        All the subclouds that are included in the same stage will be upgraded
        in parallel.

#.  To apply the upgrade strategy, use the :command:`dcmanager upgrade-strategy apply`
    command.

    .. code-block:: none

        ~(keystone_admin)]$ dcmanager upgrade-strategy apply
        +------------------------+----------------------------+
        | Field                  | Value                      |
        +------------------------+----------------------------+
        | subcloud apply type    | parallel                   |
        | max parallel subclouds | 20                         |
        | stop on failure        | False                      |
        | state                  | applying                   |
        | created_at             | 2020-02-02T14:42:13.822499 |
        | updated_at             | 2020-02-02T14:42:19.376688 |
        +------------------------+----------------------------+

#.  To show the step currently being performed on each of the subclouds, use
    the :command:`dcmanager strategy-step list` command.

    For example:
