===========================================
Firmware Update Orchestration Using the CLI
===========================================
You can configure the *Firmware Update Orchestration Strategy* using the
**sw-manager** |CLI|.
---------------
About this task
---------------
.. note::
You require administrator privileges to use **sw-manager**. You must log in
to the active controller as **user sysadmin** and source the script by
using the command, source /etc/platform/openrc to obtain administrator
privileges. Do not use sudo.
.. note::
Management-affecting alarms cannot be ignored at the indicated severity
level or higher by using relaxed alarm rules during an orchestrated
firmware update operation. For a list of management-affecting alarms, see
|prod| Fault Management: :ref:`Alarm Messages
<100-series-alarm-messages>`. To display management-affecting active
alarms, use the following command:
.. code-block:: none
~(keystone_admin)$ fm alarm-list --mgmt_affecting
During an orchestrated firmware update operation, the following alarms are
ignored even when strict restrictions are selected:
.. _tsr1590164474201-ul-hq4-nkt-tlb:
- 200.001: Maintenance host lock alarm
- 280.002: Subcloud resource out-of-sync
- 700.004: VM stopped
- 900.301: Firmware update auto apply in progress
You can use 'help' for the overall commands and also for each sub-command. For
example:
.. code-block:: none
~(keystone_admin)$ sw-manager fw-update-strategy help
usage: sw-manager fw-update-strategy [-h] ...
optional arguments:
-h, --help show this help message and exit
Firmware Update Commands:
create Create a strategy
delete Delete a strategy
apply Apply a strategy
abort Abort a strategy
show Show a strategy
.. _tsr1590164474201-section-edz-4p5-tlb:
---------------------------------------------
Firmware update orchestration strategy create
---------------------------------------------
The :command:`create` strategy subcommand with no options specified creates a
firmware update strategy with default settings. A firmware update strategy can
be created with override worker apply type concurrency with a max host
parallelism, instance action, and alarm restrictions.
**--controller-apply-type, and --storage-apply-type**
These options cannot be changed from '**ignore**' because firmware update
is only supported for worker hosts.
.. note::
Firmware update is currently only supported for hosts with worker
function. Any attempt to modify the controller or storage apply type is
rejected.
**--worker-apply-type**
This option specifies the host concurrency of the firmware update strategy:
- serial \(default\): worker hosts will be patched one at a time
- parallel: worker hosts will be updated in parallel
- At most, **parallel** will be updated at the same time
- At most, half of the hosts in a host aggregate will be updated at the
same time
- ignore: worker hosts will not be updated; strategy create will fail
Worker hosts with no instances are updated before worker hosts with instances.
**--max-parallel-worker-hosts**
This option applies to the parallel worker apply type selection to specify
the maximum worker hosts to update in parallel \(minimum: 2, maximum: 10\).
**instance-action**
This option only has significance when the stx-openstack application is
loaded and there are instances running on worker hosts. It specifies how
the strategy deals with worker host instances over the strategy execution.
**stop-start \(default\)**
Instances will be stopped before the host lock operation following the
update and then started again following the host unlock.
.. warning::
Using the **stop-start** option will result in an outage for each
instance, as it is stopped while the worker host is locked/unlocked. In
order to ensure this does not impact service, instances MUST be grouped
into anti-affinity \(or anti-affinity best effort\) server groups,
which will ensure that only a single instance in each server group is
stopped at a time.
**migrate**
Instances will be migrated off a host before it is patched \(this applies
to reboot patching only\).
**--alarm-restrictions**
This option sets how the how the firmware update orchestration behaves when
alarms are present.
To display management-affecting active alarms, use the following command:
.. code-block:: none
~(keystone_admin)$ fm alarm-list --mgmt_affecting
**strict \(default\)**
The default strict option will result in patch orchestration failing if
there are any alarms present in the system \(except for a small list of
alarms\).
**relaxed**
This option allows orchestration to proceed if alarms are present, as long
as none of these alarms are management affecting.

.. _tsr1590164474201-section-l3x-wr5-tlb:
-------------------------------------------
Firmware update orchestration strategy show
-------------------------------------------
The :command:`show` strategy subcommand displays a summary of the current state
of the strategy. A complete view of the strategy can be shown using the
**--details** option.
.. code-block:: none
~(keystone_admin)]$ sw-manager fw-update-strategy show --help
usage: sw-manager fw-update-strategy show [-h] [--details]
optional arguments:
-h, --help show this help message and exit
--details show strategy details
.. _tsr1590164474201-section-ecp-2s5-tlb:
--------------------------------------------
Firmware update orchestration strategy apply
--------------------------------------------
The :command:`apply` strategy subcommand with no options executes the firmware
update strategy from current state to the end. The apply strategy operation can
be called with the **stage-id** option to execute the next stage of the
strategy. The **stage-id** option cannot be used to execute the strategy out of
order.
.. code-block:: none
~(keystone_admin)]$ sw-manager fw-update-strategy apply --help
usage: sw-manager fw-update-strategy apply [-h] [--stage-id STAGE_ID]
optional arguments:
-h, --help show this help message and exit
--stage-id STAGE_ID stage identifier to apply
.. _tsr1590164474201-section-lmp-ks5-tlb:
--------------------------------------------
Firmware update orchestration strategy abort
--------------------------------------------
The **abort** strategy subcommand with no options sets the strategy to abort
after the current applying stage is complete. The abort strategy operation can
be called with the **stage-id** option to specify that the strategy abort
before executing the next stage of the strategy. The **stage-id** option cannot
be used to execute the strategy out of order.
.. code-block:: none
~(keystone_admin)]$ sw-manager fw-update-strategy abort --help
usage: sw-manager fw-update-strategy abort [-h] [--stage-id STAGE_ID]
optional arguments:

---------------------------------------------
The **delete** strategy subcommand with no options deletes a strategy.
