zhmc_partition – Create partitions

Synopsis

  • Gather facts about a partition of a CPC (Z system), including its HBAs, NICs, virtual functions, and crypto configuration including crypto adapters.

  • Create, update, or delete a partition. The HBAs, NICs, and virtual functions of the partition are managed by separate Ansible modules.

  • Start or stop a partition.

Requirements

  • The targeted Z system must be in the Dynamic Partition Manager (DPM) operational mode.

  • The HMC userid must have these task permissions: ‘New Partition’, ‘Delete Partition’, ‘Partition Details’, ‘Start Partition’, ‘Stop Partition’, ‘Dump Partition’, ‘PSW Restart’.

  • The HMC userid must have object-access permissions to these objects: Target partitions, CPCs of target partitions, Crypto adapters of target partitions.

Parameters

hmc_host

The hostname or IP address of the HMC.

required: True
type: str
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 partition.

required: True
type: str
name

The name of the target partition.

required: True
type: str
state

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

* absent: Ensures that the partition does not exist in the specified CPC.

* stopped: Ensures that the partition exists in the specified CPC, has the specified properties, and is in one of the inactive statuses (‘stopped’, ‘terminated’, ‘paused’, ‘reservation-error’).

* active: Ensures that the partition exists in the specified CPC, has the specified properties, and is in one of the active statuses (‘active’, ‘degraded’).

* facts: Returns the partition properties and the properties of its child resources (HBAs, NICs, and virtual functions).

required: True
type: str
choices: absent, stopped, active, facts
properties

Dictionary with input properties for the partition, for state=stopped and state=active. 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. Will be ignored for state=absent.

The possible input properties in this dictionary are the properties defined as writeable in the data model for Partition resources (where the property names contain underscores instead of hyphens), with the following exceptions:

* name: Cannot be specified because the name has already been specified in the name module parameter.

* type: Cannot be changed once the partition exists, because updating it is not supported.

* boot_storage_device: Cannot be specified because this information is specified using the artificial property boot_storage_hba_name.

* boot_network_device: Cannot be specified because this information is specified using the artificial property boot_network_nic_name.

* boot_storage_hba_name: The name of the HBA whose URI is used to construct boot_storage_device. Specifying it requires that the partition exists. Only valid when the partition is on a z13.

* boot_storage_group_name: The name of the storage group that contains the boot volume specified with boot_storage_volume_name.

* boot_storage_volume_name: The name of the storage volume in storage group boot_storage_group_name whose URI is used to construct boot_storage_volume. This property is mutually exclusive with boot_storage_volume. Specifying it requires that the partition and storage group exist. Only valid when the partition is on a z14 or later.

* boot_network_nic_name: The name of the NIC whose URI is used to construct boot_network_device. Specifying it requires that the partition exists.

* crypto_configuration: The crypto configuration for the partition, in the format of the crypto-configuration property of the partition (see :term:`HMC API` for details), with the exception that adapters are specified with their names in field crypto_adapter_names instead of their URIs in field crypto_adapter_uris. If the crypto_adapter_names field is null, all crypto adapters of the CPC will be used.

Properties omitted in this dictionary will remain unchanged when the partition already exists, and will get the default value defined in the data model for partitions in the :term:`HMC API` when the partition is being created.

required: False
type: dict
expand_storage_groups

Boolean that controls whether the returned partition contains an additional artificial property ‘storage-groups’ that is the list of storage groups attached to the partition, with properties as described for the zhmc_storage_group module with expand=true.

required: False
type: bool
expand_crypto_adapters

Boolean that controls whether the returned partition contains an additional artificial property ‘crypto-adapters’ in its ‘crypto-configuration’ property that is the list of crypto adapters attached to the partition, with properties as described for the zhmc_adapter module.

required: False
type: bool
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
