zhmc_virtual_function – Manage a virtual function of a partition (DPM mode)

Synopsis

  • Create, update, or delete a virtual function in a partition of a CPC (Z system).

  • Note that the Ansible module zhmc_partition can be used to gather facts about existing virtual functions of 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: ‘Partition Details’.

  • The HMC userid must have object-access permissions to these objects: Backing accelerator adapters of the target virtual functions, partitions of the target virtual functions, CPCs of these partitions.

Parameters

hmc_host

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 hmc_auth.session_id.

required: False
type: str
password

The password for authenticating with the HMC. This is mutually exclusive with providing hmc_auth.session_id.

required: False
type: str
session_id

HMC session ID to be used. This is mutually exclusive with providing hmc_auth.userid and hmc_auth.password and can be created as described in the 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 hmc_auth.ca_certs parameter. If False, ignore what is specified in the hmc_auth.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 partition containing the virtual function.

required: True
type: str
partition_name

The name of the partition containing the virtual function.

required: True
type: str
name

The name of the target virtual function that is managed. If the virtual function needs to be created, this value becomes its name.

required: True
type: str
state

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

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

* present: Ensures that the virtual function exists in the specified partition and has the specified properties.

required: True
type: str
choices: absent, present
properties

Dictionary with input properties for the virtual function, for state=present. 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 Virtual Function 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.

* adapter_uri: Cannot be specified because this information is specified using the artificial property adapter_name.

* adapter_name: The name of the adapter that backs the target virtual function.

Properties omitted in this dictionary will remain unchanged when the virtual function already exists, and will get the default value defined in the data model for virtual functions when the virtual function is being created.

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

Examples

---
# Note: The following examples assume that some variables named 'my_*' are set.

- name: Ensure virtual function exists in the partition
  zhmc_partition:
    hmc_host: "{{ my_hmc_host }}"
    hmc_auth: "{{ my_hmc_auth }}"
    cpc_name: "{{ my_cpc_name }}"
    partition_name: "{{ my_partition_name }}"
    name: "{{ my_vfunction_name }}"
    state: present
    properties:
      adapter_name: "ABC-123"
      description: "The accelerator adapter"
      device_number: "033F"
  register: vfunction1

- name: Ensure virtual function does not exist in the partition
  zhmc_partition:
    hmc_host: "{{ my_hmc_host }}"
    hmc_auth: "{{ my_hmc_auth }}"
    cpc_name: "{{ my_cpc_name }}"
    partition_name: "{{ my_partition_name }}"
    name: "{{ my_vfunction_name }}"
    state: absent

Return Values

changed

Indicates if any change has been made by the module. For state=facts, always will be false.

returned: always
type: bool
msg

An error message that describes the failure.

returned: failure
type: str
virtual_function

For state=absent, an empty dictionary.

For state=present, the resource properties of the virtual function after any changes.

returned: success
type: dict
name

Virtual function name

type: str
{property}

Additional properties of the virtual function, as described in the data model of the ‘Virtual Function’ element object of the ‘Partition’ object in the HMC API book. The property names have hyphens (-) as described in that book.

type: raw
