zhmc_storage_volume – Create storage volumes
Synopsis
Gather facts about a storage volume in a storage group associated with a CPC (Z system).
Create, delete, or update a storage volume in a storage group associated with a CPC.
Requirements
The targeted Z system must be of generation z14 or later (to have the “dpm-storage-management” firmware feature) and must be in the Dynamic Partition Manager (DPM) operational mode.
The HMC userid must have these task permissions: ‘Configure Storage - System Programmer’.
The HMC userid must have object-access permissions to these objects: Target storage groups.
Parameters
- hmc_host
The hostname or IP address of the HMC.
required: Truetype: str- hmc_auth
The authentication credentials for the HMC.
required: Truetype: dict- userid
The userid (username) for authenticating with the HMC. This is mutually exclusive with providing
session_id
.required: Falsetype: str- password
The password for authenticating with the HMC. This is mutually exclusive with providing
session_id
.required: Falsetype: str- session_id
HMC session ID to be used. This is mutually exclusive with providing
userid
andpassword
and can be created as described in :ref:`zhmc_session_module`.required: Falsetype: 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: Falsetype: str- verify
If True (default), verify the HMC certificate as specified in the
ca_certs
parameter. If False, ignore what is specified in theca_certs
parameter and do not verify the HMC certificate.required: Falsetype: booldefault: True
- cpc_name
The name of the CPC associated with the storage group containing the target storage volume.
required: Truetype: str- storage_group_name
The name of the storage group containing the target storage volume.
required: Truetype: str- name
The name of the target storage volume.
required: Truetype: str- state
The desired state for the storage volume. All states are fully idempotent within the limits of the properties that can be changed:
*
absent
: Ensures that the storage volume does not exist in the specified storage group.*
present
: Ensures that the storage volume exists in the specified storage group, and has the specified properties.*
facts
: Returns the storage volume properties.required: Truetype: strchoices: absent, present, facts- properties
Dictionary with desired properties for the storage volume. Used for
state=present
; ignored forstate=absent|facts
. Dictionary key is the property name with underscores instead of hyphens, and dictionary 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 Storage Volume 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 thename
module parameter.Properties omitted in this dictionary will remain unchanged when the storage volume already exists, and will get the default value defined in the data model for storage volumes in the :term:`HMC API` when the storage volume is being created.
required: Falsetype: 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: Falsetype: str

Notes
Note
This module manages only the knowledge of the Z system about its storage, but does not perform any actions against the storage subsystems or SAN switches attached to the Z system.
Return Values
- changed
Indicates if any change has been made by the module. For
state=facts
, always will be false.returned: alwaystype: bool- msg
An error message that describes the failure.
returned: failuretype: str- storage_volume
For
state=absent
, an empty dictionary.For
state=present|facts
, the resource properties of the storage volume after any changes.returned: successtype: dictsample:{ "active-size": 128.0, "class": "storage-volume", "description": "Boot volume", "element-id": "f02e2632-200a-11e9-8748-00106f239c31", "element-uri": "/api/storage-groups/edd782f2-200a-11e9-a142-00106f239c31/storage-volumes/f02e2632-200a-11e9-8748-00106f239c31", "fulfillment-state": "complete", "name": "MGMT1_MGMT1-boot", "parent": "/api/storage-groups/edd782f2-200a-11e9-a142-00106f239c31", "paths": [ { "device-number": "0015", "logical-unit-number": "0000000000000000", "partition-uri": "/api/partitions/009c0f4c-3588-11e9-bad3-00106f239d19", "target-world-wide-port-name": "5005076810260382" } ], "size": 128.0, "type": "fcp", "usage": "boot", "uuid": "600507681081001D4800000000000083" }
