=======================================================
Distributed Upgrade Orchestration Process using the CLI
=======================================================
Distributed upgrade orchestration can be initiated after the System Controller
has been successfully upgraded.
For more information on Prestaging Subcloud Orchestration see,
:ref:`prestage-subcloud-orchestration-eb516473582f`.
.. 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. The install values as well as `bmc_password`
for each |AIO-SX| subcloud must have already been saved in the system
controller database before the start of orchestrated subcloud upgrade.
.. note::
The following command is only required if the |AIO-SX| subcloud install
values and `bmc_password` have never been provided using
:command:`dcmanager CLI` command.
.. 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>`.
- Duplex (|AIO-DX|/Standard) upgrades are supported, and they do not
require remote install using Redfish.
- 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.
- The size and format of the persistent filesystem, /opt/platform-backup, of
each subcloud must be 30GiB (or larger) and ext4 respectively. From the shell
on a subcloud, use the following command to view the details of its
persistent file system:
:command:`df -Th /opt/platform-backup`
The type must be ext4 and the size must be 30GiB. 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/sda1 ext4 29G 6.9G 21G 26% /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\*`
You can configure an upgrade Distributed Cloud orchestration strategy using the
dcmanager CLI or the Horizon web interface. If you prefer to use Horizon, see
:ref:`create-an-upgrade-orchestration-using-horizon-9f8c6c2f3706`.
.. 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 | subcloud-1| managed | online | out-of-sync |
| 2 | subcloud-2| managed | online | out-of-sync |
| 3 | subcloud-3| managed | online | out-of-sync |
| 4 | subcloud-4| managed | online | out-of-sync |
+----+-----------+--------------+--------------------+-------------+
.. note::
The subclouds are out-of-sync because the load-sync-status is out-of-sync.
All of the above subclouds are not upgrade-current and, therefore, need
to be upgraded.
To see synchronization details for a subcloud, use the following command:
.. code-block:: none
~(keystone_admin)]$ dcmanager subcloud show subcloud1
+-----------------------------+------------------------------+
| Field | Value |
+-----------------------------+------------------------------+
| id | 1 |
| name | subcloud-1 |
| description | None |
| location | None |
| software_version | nn.nn |
| management | managed |
| availability | online |
| deploy_status | complete |
| management_subnet | fd01:82::0/64 |
| management_start_ip | fd01:82::2 |
| management_end_ip | fd01:82::11 |
| management_gateway_ip | fd01:82::1 |
| systemcontroller_gateway_ip | fd01:81::1 |
| group_id | 1 |
| created_at | 2021-06-07 21:05:16.224664 |

| patching_sync_status | in-sync |
| platform_sync_status | in-sync |
+-----------------------------+------------------------------+
#. 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] \
[--force] \
[<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 2).
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.
**force**
Upgrade both online and offline subclouds. Can be used for a single
subcloud, or a subcloud group.
For example:
.. code-block:: none
~(keystone_admin)]$ dcmanager upgrade-strategy create
+------------------------+----------------------------+
| Field | Value |
+------------------------+----------------------------+
| strategy type | upgrade |
| subcloud apply type | parallel |
| max parallel subclouds | 2 |
| 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 | 2 |
| 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 | 2 |
| 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:
.. code-block:: none
~(keystone_admin)]$ dcmanager strategy-step list
+------------------+-------+-----------------------+-------------------+----------------------------+----------------------------+
| cloud | stage | state | details | started_at | finished_at |
+------------------+-------+-----------------------+-------------------+----------------------------+----------------------------+
| subcloud-1 | 1 | complete | | 2021-06-11 14:12:12.262001 | 2021-06-11 14:15:52.450908 |
| subcloud-4 | 1 | activating upgrade | | 2021-06-11 14:16:02.457588 | None |
| subcloud-5 | 2 | initial | | None | None |
| subcloud-6 | 2 | initial | | None | None |
+------------------+-------+-------------+-----------------------------+----------------------------+----------------------------+
#. To show the step currently being performed on a subcloud, use the
:command:`dcmanager strategy-step show` <subcloud> command.
.. code-block:: none
~(keystone_admin)]$ dcmanager strategy-step show <subcloud>
#. When all the subclouds within the distributed upgrade orchestration indicate
they have entered the complete state, delete the upgrade strategy, using
the :command:`dcmanager upgrade-strategy delete` command.
.. code-block:: none
~(keystone_admin)]$ dcmanager upgrade-strategy delete
+------------------------+----------------------------+
| Field | Value |
+------------------------+----------------------------+
| subcloud apply type | parallel |
| max parallel subclouds | 2 |
| stop on failure | False |
| state | deleting |
| created_at | 2020-03-23T20:04:50.992444 |
