zhmc_lpar – Manage LPARs

Synopsis 

Gather facts about an LPAR of a CPC (Z system) in classic mode.
Update modifiable properties of an active LPAR.
Activate an LPAR and update its properties.
Load an LPAR and update its properties.
Deactivate an LPAR using the ‘Deactivate Logical Partition’ operation.
Initialize for load using the ‘Reset Clear’ or ‘Reset Normal’ operations.

Requirements 

The targeted CPC must be in the classic operational mode.
The HMC userid must have these task permissions: ‘Activate’, ‘Deactivate’, ‘Logical Processor Add’ (if cores are updated), ‘Firmware Details’ (if ‘zaware-…’ properties are updated), ‘Change Object Options’ or ‘Customize/Delete Activation Profiles’ (if ‘next-activation-profile-name’ property is updated).
The HMC userid must have object-access permissions to these objects: Target LPARs, CPCs of target LPARs.

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

cpc_name

The name of the CPC with the target LPAR.

required: True

type: str

name

The name of the target LPAR.

required: True

type: str

state

The desired state for the LPAR:

* inactive: Ensures that the LPAR is inactive (i.e. status ‘not-activated’), unless the LPAR is currently operating and the force parameter was not set to True. Properties cannot be updated. The LPAR is deactivated if needed.

* active: Ensures that the LPAR is at least active (i.e. status is ‘not-operating’, ‘operating’ or ‘exceptions’), and then ensures that the LPAR properties have the specified values. The LPAR is activated if needed using the ‘Activate Logical Partition’ operation. In certain cases, that operation will automatically load the LPAR. For details, see the activation_profile_name parameter.

* loaded: Ensures that the LPAR is loaded (i.e. status is ‘operating’ or ‘exceptions’), and then ensures that the LPAR properties have the specified values. The LPAR is first activated if needed using the ‘Activate Logical Partition’ operation, and then loaded if needed using the ‘Load Logical Partition’ operation. For details, see the activation_profile_name parameter.

* reset_clear: Performs the ‘Reset Clear’ HMC operation on the LPAR. This initializes the LPAR for loading by clearing its pending interruptions, resetting its channel subsystem, resetting its processors, and clearing its memory). The LPAR must be in status ‘not-operating’, ‘operating’, or ‘exceptions’. If the LPAR status is ‘operating’ or ‘exceptions’, the operation will fail unless the force parameter is set to True. Properties cannot be updated.

* reset_normal: Performs the ‘Reset Normal’ HMC operation on the LPAR. This initializes the LPAR for loading by clearing its pending interruptions, resetting its channel subsystem, and resetting its processors). It does not clear the memory. The LPAR must be in status ‘not-operating’, ‘operating’, or ‘exceptions’. If the LPAR status is ‘operating’ or ‘exceptions’, the operation will fail unless the force parameter is set to True. Properties cannot be updated.

* set: Ensures that the LPAR properties have the specified values. Requires that the LPAR is at least active (i.e. status is ‘not-operating’, ‘operating’ or ‘exceptions’) but does not activate the LPAR if that is not the case.

* facts: Returns the current LPAR properties.

In all cases, the LPAR must exist.

required: True
type: str
choices: inactive, active, loaded, reset_clear, reset_normal, set, facts

select_properties

Limits the returned properties of the LPAR 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 specified properties are passed to the ‘Get Logical Partition 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 image or load activation profile to be used when the LPAR needs to be activated, for state=active and state=loaded.

This parameter is not allowed for the other state values.

Default: The image or load activation profile specified in the ‘next-activation-profile-name’ property of the LPAR is used when the LPAR needs to be activated.

For LPARs with activation modes other than SSC or zAware, the following applies: If an image activation profile is specified, the ‘load-at-activation’ property of the image activation profile determines whether an automatic load is performed, using the load parameters from the image activation profile. If a load activation profile is specified, an automatic load is always performed, using the parameters from the load activation profile.

For LPARs with activation modes SSC or zAware, the following applies: A load activation profile cannot be specified. The LPAR is always auto-loaded using internal load parameters (ignoring the ‘load-at-activation’ property and the load-related properties of their image activation profile).

required: False

type: str

load_address

The hexadecimal address of an I/O device that provides access to the control program to be loaded, for state=loaded.

This parameter is not allowed for the other state values.

This parameter is used only when the LPAR is explicitly loaded using the ‘Load Logical Partition’ operation. It is not used when the LPAR is automatically loaded during the ‘Activate Logical Partition’ operation.

For z13 and older generations, this parameter is required. Starting with z14, this parameter is optional and defaults to the load address specified in the ‘last-used-load-address’ property of the LPAR.

required: False

type: str

load_parameter

A parameter string that is passed to the control program when loading it, for state=loaded.

This parameter is not allowed for the other state values.

This parameter is used only when the LPAR is explicitly loaded using the ‘Load Logical Partition’ operation. It is not used when the LPAR is automatically loaded during the ‘Activate Logical Partition’ operation.

required: False

type: str

clear_indicator

Controls whether memory is cleared before performing the load, for state=loaded.

This parameter is not allowed for the other state values.

This parameter is used only when the LPAR is explicitly loaded using the ‘Load Logical Partition’ operation. It is not used when the LPAR is automatically loaded during the ‘Activate Logical Partition’ operation.

required: False
type: bool
default: True

store_status_indicator

Controls whether the current values of CPU timer, clock comparator, program status word, and the contents of the processor registers are stored to their assigned absolute storage locations, for state=loaded.

This parameter is not allowed for the other state values.

This parameter is used only when the LPAR is explicitly loaded using the ‘Load Logical Partition’ operation. It is not used when the LPAR is automatically loaded during the ‘Activate Logical Partition’ operation.

required: False

type: bool

timeout

Timeout in seconds, for activate (if needed) and for load (if needed).

required: False
type: int
default: 60

force

Controls whether operations that change the LPAR status are performed when the LPAR is currently loaded (i.e. status ‘operating’ or ‘exceptions’):

If True, such operations are performed regardless of the current LPAR status.

If False (default), such operations are performed only if the LPAR is not currently loaded, and are rejected otherwise.

required: False

type: bool

os_ipl_token

Setting this parameter for state=reset_clear or state=reset_normal requests that the corresponding HMC operations only be performed if the provided value matches the current value of the ‘os-ipl-token’ property of the LPAR, and be rejected otherwise. Note that the ‘os-ipl-token’ property of the LPAR is set by the operating system and is set only by some operating systems, such as z/OS. This parameter is ignored for other state values.

required: False

type: str

properties

Dictionary with new values for the LPAR properties, for state=active, state=loaded and state=set. Key is the property name with underscores instead of hyphens, and value is the property value in YAML syntax. Integer properties may also be provided as decimal strings.

The possible input properties in this dictionary are the properties defined as writeable in the data model for LPAR resources (where the property names contain underscores instead of hyphens).

Properties omitted in this dictionary will not be updated.

This parameter is not allowed for the other state values.

required: False

type: dict

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
