Overview
========
The zhmcclient package is a client library
written in pure Python that interacts with the Web Services API of the Hardware
Management Console (HMC) of `IBM Z`_ or `LinuxONE`_ machines. The goal of
this package is to make the HMC Web Services API easily consumable for Python
programmers.
.. _IBM Z: http://www.ibm.com/systems/z/
.. _LinuxONE: http://www.ibm.com/systems/linuxone/
The HMC Web Services API is the access point for any external tools to
manage the IBM Z or LinuxONE platform. It supports management of the
lifecycle and configuration of various platform resources, such as partitions,
CPU, memory, virtual switches, I/O adapters, and more.
The zhmcclient package encapsulates both protocols supported by the HMC Web
Services API:
* REST over HTTPS for request/response-style operations driven by the client.
Most of these operations complete synchronously, but some long-running tasks
complete asynchronously.
* JMS (Java Messaging Services) for notifications from the HMC to the client.
This can be used to be notified about changes in the system, or about
completion of asynchronous tasks started using REST.
Installation
============
The quick way:
.. code-block:: bash
$ pip install zhmcclient
For more details, see the `Installation section`_ in the documentation.
.. _Installation section: http://python-zhmcclient.readthedocs.io/en/latest/intro.html#installation
Quickstart
===========
The following example code lists the partitions on CPCs in DPM mode that are
accessible for the user:
.. code-block:: python
#!/usr/bin/env python
import zhmcclient
import requests.packages.urllib3
requests.packages.urllib3.disable_warnings()
# Set these variables for your environment:
host = "<IP address or hostname of the HMC>"
userid = "<userid on that HMC>"
password = "<password of that HMC userid>"
verify_cert = False
session = zhmcclient.Session(host, userid, password, verify_cert=verify_cert)
client = zhmcclient.Client(session)
console = client.consoles.console
partitions = console.list_permitted_partitions()
for part in partitions:
cpc = part.manager.parent
print("{} {}".format(cpc.name, part.name))
Possible output when running the script:
.. code-block:: text
P000S67B PART1
P000S67B PART2
P0000M96 PART1
Documentation and Change Log

zhmc CLI
========
Before version 0.18.0 of the zhmcclient package, it contained the zhmc CLI.
Starting with zhmcclient version 0.18.0, the zhmc CLI has been moved from this
project into the new `zhmccli project`_.
If your project uses the zhmc CLI, and you are upgrading the zhmcclient
package from before 0.18.0 to 0.18.0 or later, your project will need to add
the `zhmccli package`_ to its dependencies.
