zhmc_cpc – Manage CPCs

Synopsis 

Deactivate/Stop a CPC (Z system).
Activate/Start a CPC and update its properties.
Gather facts about a CPC, and for DPM operational mode, including its adapters, partitions and storage groups.
Update the properties of a CPC.
Upgrade the SE firmware of a CPC.

Requirements 

The HMC userid must have these task permissions: ‘CPC Details’. For CPCs in DMP mode: ‘Start’, ‘Stop’. For CPCs in classic mode: ‘Activate’, ‘Deactivate’.
The HMC userid must have object-access permissions to these objects: Target CPCs. For CPCs in DMP mode: Adapters, partitions, storage groups of target CPCs. For CPCs in classic mode: LPARs, activation profiles of target CPCs.

The hostnames or IP addresses of a single HMC or of a list of redundant HMCs. A single HMC can be specified as a string type or as an HMC list with one item. An HMC list can be specified as a list type or as a string type containing a Python list representation.

The first available HMC of a list of redundant HMCs is used for the entire execution of the module.

required: True

type: raw

hmc_auth

The authentication credentials for the HMC.

required: True

type: dict

userid: The userid (username) for authenticating with the HMC. This is mutually exclusive with providing session_id.

required: False

type: str
password: The password for authenticating with the HMC. This is mutually exclusive with providing session_id.

required: False

type: str
session_id: HMC session ID to be used. This is mutually exclusive with providing userid and password and can be created as described in :ref:`zhmc_session_module`.

required: False

type: str
ca_certs: Path name of certificate file or certificate directory to be used for verifying the HMC certificate. If null (default), the path name in the ‘REQUESTS_CA_BUNDLE’ environment variable or the path name in the ‘CURL_CA_BUNDLE’ environment variable is used, or if neither of these variables is set, the certificates in the Mozilla CA Certificate List provided by the ‘certifi’ Python package are used for verifying the HMC certificate.

required: False

type: str
verify: If True (default), verify the HMC certificate as specified in the ca_certs parameter. If False, ignore what is specified in the ca_certs parameter and do not verify the HMC certificate.

required: False

type: bool

default: True

name

The name of the target CPC.

required: True

type: str

state

The desired state for the CPC. All states are fully idempotent within the limits of the properties that can be changed:

* inactive: Ensures the CPC is inactive.

* active: Ensures the CPC is active and then ensures that the CPC has the specified properties. The operational mode of the CPC cannot be changed.

* set: Ensures that the CPC has the specified properties.

* facts: Returns the CPC properties including its child resources.

* upgrade: Upgrades the firmware of the SE of the CPC and returns the new facts after the upgrade. If the SE firmware is already at the requested bundle level, nothing is changed and the module succeeds.

required: True
type: str
choices: inactive, active, set, facts, upgrade

select_properties

Limits the returned properties of the CPC to those specified in this parameter plus those specified in the properties parameter.

The properties can be specified with underscores or hyphens in their names.

Null indicates not to limit the returned properties in this way.

This parameter is ignored for state values that cause no properties to be returned.

The returned child resources (adapters, partitions, storage groups) cannot be excluded using this parameter.

The specified properties are passed to the ‘Get CPC Properties’ HMC operation using the ‘properties’ query parameter and save time for the HMC to pull together all properties.

required: False
type: list
elements: str

activation_profile_name

The name of the reset activation profile to be used when activating the CPC in the classic operational mode, for state=active. This parameter is ignored when the CPC is in classic mode and was already active, and when the CPC is in DPM mode.

Default: The reset activation profile specified in the ‘next-activation-profile-name’ property of the CPC.

This parameter is not allowed for the other state values.

required: False

type: str

properties

Only for state=set and state=active: New values for the properties of the CPC. Properties omitted in this dictionary will remain unchanged. This parameter will be ignored for other state values.

The parameter is a dictionary. The key of each dictionary item is the property name as specified in the data model for CPC resources, with underscores instead of hyphens. The value of each dictionary item is the property value (in YAML syntax). Integer properties may also be provided as decimal strings.

The possible properties in this dictionary are the properties defined as writeable in the data model for CPC resources.

required: False

type: dict

bundle_level

Name of the bundle to be installed on the SE of the CPC (e.g. ‘S71’)

Required for state=upgrade

required: False

type: str

upgrade_timeout

Timeout in seconds for waiting for completion of upgrade (e.g. 10800)

required: False
type: int
default: 10800

accept_firmware

Accept the previous bundle level before installing the new level.

Optional for state=upgrade, default: True

required: False
type: bool
default: True

log_file

File path of a log file to which the logic flow of this module as well as interactions with the HMC are logged. If null, logging will be propagated to the Python root logger.

required: False

type: str
