List the permitted adapters of all CPCs managed by this HMC.
The result will include all adapters of any DPM CPCs and z15 or later
classic-mode CPCs that are managed by the targeted HMC and to which the
user has object-access permission.
*If 'additional_properties' is not used, requires HMC API version 4.1 or
later (= HMC version 2.16.0 GA-level) and otherwise raises
HTTPError(404.4).*
*If 'additional_properties' is used, requires HMC API version 4.10 or
later (= HMC version 2.16.0 plus some post-GA code level) and
otherwise raises HTTPError(404.4).*
The adapters in the result can be additionally limited by specifying
filter arguments.
Authorization requirements:
* Object permission to the adapter objects included in the result.
Parameters:
full_properties (bool):
Controls whether the full set of resource properties for the
returned Adapter objects should be retrieved, vs. only a short
set.
filter_args (dict):
Filter arguments for limiting the adapters in the result.
`None` causes no filtering to happen.
The following filter arguments are supported by server-side
filtering:
* name (string): Limits the result to adapters whose name
match the specified regular expression.
* adapter-id (string): Limits the result to adapters with a matching
"adapter-id" property value (i.e. PCHID).
* adapter-family (string): Limits the result to adapters with a
matching "adapter-family" property value (e.g. "hipersockets").
* type (string): Limits the result to adapters with a matching
"type" property value (e.g. "hipersockets").
* status (string): Limits the result to adapters with a matching
"status" property value.
* firmware-update-pending (bool): Limits the result to adapters with
a matching firmware-update-pending state.
* cpc-name (string): Limits the result to adapters whose CPC
has a name that matches the specified regular expression.
* dpm-enabled (bool): Limits the result to adapters whose CPC
has a matching "dpm-enabled" property.
Any other valid property of adapters is supported by
client-side filtering:
* <property-name>: Any other property of adapters.
additional_properties (list of string):
List of property names that are to be returned in addition to the
default properties.
Returns:
: A list of :class:`~zhmcclient.Adapter` objects.
If no additional or full properties are specified, the returned
adapters will have the following properties:
* object-uri, name, adapter-id, adapter-family, type, status,
* firmware-update-pending (if CPC >=2.16 and
LI_1580_CRYPTO_AUTO_TOGGLE feature is enabled)
and the following properties for their parent CPC:
* cpc-name (CPC property 'name')
* cpc-object-uri (CPC property 'object-uri')
* se-version (CPC property 'se-version')
* dpm-enabled (CPC property 'dpm-enabled')

"""
Upgrades the firmware on this HMC to a new bundle level.
This is done by performing the "Console Single Step Install" operation
which performs the following steps:
* If `accept_firmware` is True, the firmware currently installed on the
this HMC is accepted. Note that once firmware is accepted, it
cannot be removed.
* A backup of the this HMC is performed to the specified backup device.
* The new firmware identified by the bundle-level field is retrieved
from the IBM support site or from an FTP server, and installed.
* The newly installed firmware is activated, which includes rebooting
this HMC.
Note that it is not possible to downgrade the HMC firmware with this
operation.
For HMCs that run on an HMA that also hosts an SE (e.g. z16 and higher),
the HMC firmware can only be upgraded if the HMA hosts an alternate SE.
Authorization requirements:
* Task permission to the "Single Step Console Internal Code" task.
Parameters:
bundle_level (string): Name of the bundle to be installed on the HMC
(e.g. 'H71').
If `None`, all locally available code changes, or in case of
retrieving code changes from an FTP server, all code changes on
the FTP server, will be installed.
backup_location_type (string): Type of backup location for the
HMC backup that is performed:
- "ftp": The FTP server that was used for the last console backup
as defined on the "Configure Backup Settings" user interface
task in the HMC GUI.
- "usb": The USB storage device mounted to the HMC.
accept_firmware (bool): Accept the previous bundle level before
installing the new level.
ftp_host (string): The hostname for the FTP server from which
the firmware will be retrieved, or `None` to retrieve it from the
IBM support site.
ftp_protocol (string): The protocol to connect to the FTP
server, if the firmware will be retrieved from an FTP server,
or `None`. Valid values are: "ftp", "ftps", "sftp".
ftp_user (string): The username for the FTP server login,
if the firmware will be retrieved from an FTP server, or `None`.
ftp_password (string): The password for the FTP server login,
if the firmware will be retrieved from an FTP server, or `None`.
ftp_directory (string): The path name of the directory on the
FTP server with the firmware files,
if the firmware will be retrieved from an FTP server, or `None`.
wait_for_completion (bool):
Boolean controlling whether this method should wait for completion
of the requested asynchronous HMC operation including any HMC
restarts, as follows:
* If `True`, this method will wait for completion of the
asynchronous job performing the operation including any HMC
restarts.
* If `False`, this method will return immediately once the HMC has
accepted the request to perform the operation.
operation_timeout (:term:`number`):
Timeout in seconds, for waiting for completion of the asynchronous
job performing the operation including any HMC restarts. The
special value 0 means that no timeout is set. `None` means that
the default async operation timeout of the session is used. If the
timeout expires when `wait_for_completion=True`, a
:exc:`~zhmcclient.OperationTimeout` is raised.
Returns:
`None` or :class:`~zhmcclient.Job`:
If `wait_for_completion` is `True`, returns `None`.
If `wait_for_completion` is `False`, returns a
:class:`~zhmcclient.Job` object representing the asynchronously
executing job on the HMC. The Job object will be valid across
any HMC restarts that occur during the upgrade operation.
This job supports cancellation. Note there are only a few
interruption points in the firmware install process, so it may be
some time before the job is canceled, and after some point, will
continue on to completion. The job status and reason codes will
indicate whether the job was canceled or ran to completion. If the
job is successfully canceled, any steps that were successfully
completed will not be rolled back.
Raises:
:exc:`~zhmcclient.HTTPError`
:exc:`~zhmcclient.ParseError`
:exc:`~zhmcclient.AuthError`
:exc:`~zhmcclient.ConnectionError`
:exc:`~zhmcclient.OperationTimeout`: The timeout expired while
waiting for completion of the operation.
