The IBM Z HMC collection enables automation with the IBM Z Hardware Management Console (HMC) to manage platform resources on IBM Z and IBM LinuxONE machines.
The IBM Z HMC collection is part of the Red Hat® Ansible Certified Content for IBM Z® offering that brings Ansible automation to IBM Z®.
This collection supports automation tasks on the IBM Z HMC such as creating, updating or deleting partitions, accesssing operating system messages, configuring adapters, managing HMC users, upgrading the SE and HMC firmware, and many more. It supports CPCs in classic mode and in DPM mode.
The IBM Z HMC collection uses the Web Services API of the HMC and therefore its modules run on the Ansible control node (there is no separate Ansible managed node in this case).
For guides and reference, please review the documentation or the Z HMC section in the unified documentation.
Before you install the IBM Z HMC collection, you must have a minimum Python version and Ansible version on the Ansible control node. The documentation section Support matrix details the specific version requirements.
Before using this collection, you need to install it with the Ansible Galaxy command-line tool:
ansible-galaxy collection install ibm.ibm_zhmcYou can also include it in a requirements.yml file and install it with
ansible-galaxy collection install -r requirements.yml, using the format:
collections:
- name: ibm.ibm_zhmcThe installation of the collection will not cause any required Python packages
to be installed. They need to be installed separately, either as OS-level
packages or as Python packages, depending on how you manage the Python packages
on your system. A requirements.txt file is provided in the installation
directory of the ibm.ibm_zhmc collection for that purpose, either for direct use
with pip install -r requirements.txt, or for manually checking and installing
the corresponding OS-level packages.
Note that if you install the collection from Ansible Galaxy, it will not be upgraded automatically when you upgrade the Ansible (OS-level or Python) package.
To upgrade the collection to the latest available version, run the following command:
ansible-galaxy collection install ibm.ibm_zhmc --upgradeYou can also install a specific version of the collection, for example, if you need to downgrade for some reason. For example, the following command installs version 1.0.0:
ansible-galaxy collection install ibm.ibm_zhmc:1.0.0-

This community is not currently accepting contributions. However, we encourage you to open git issues for bugs, comments or feature requests and check back periodically for when community contributions will be accepted in the near future.
Review the development docs to learn how you can create an environment and test the collections modules.
If you would like to communicate with this community, you can do so through the following options:
- GitHub IBM Z HMC issues.
- Discord ansible in System Z Enthusiasts
- Invitation link for server System Z Enthusiasts

As Red Hat Ansible Certified Content, this collection is entitled to support through Ansible Automation Platform (AAP). After creating a Red Hat support case, if it is determined the issue belongs to IBM, Red Hat will instruct you to create an IBM support case and share the case number with Red Hat so that a collaboration can begin between Red Hat and IBM.
If a support case cannot be opened with Red Hat and the collection has been obtained either from Galaxy or its GitHub repo, there is community support available at no charge. Community support is limited to the collection; community support does not include any of the Ansible Automation Platform components or Ansible.
The current supported versions of this collection can be found listed in the following section.
The collection's cumulative release notes can be reviewed here. Note, some collection versions release before an ansible-core version reaches End of Life (EOL), thus the version of ansible-core that is supported must be a version that is currently supported.
For AAP users, to see the supported ansible-core versions, review the AAP Life Cycle.
For Galaxy and GitHub users, to see the supported ansible-core versions, review the ansible-core support matrix.
The collection's changelogs can be reviewed in the following table:
