Welcome to PyU4V 10.0 ===================== | |Maintenance| |OpenSource| |AskUs| |License| |Test| |Build| |Docs| | |Language| |PyVersions| |Unisphere| |Platform| |DTotal| |DMonth| |DWeek| Overview -------- PyU4V is a Python module that simplifies interaction with the Unisphere for PowerMax REST API. It wraps REST calls with simple APIs that abstract the HTTP request and response handling. Full documentation and user guides can be found in PyU4V's ReadTheDocs_. Note You can get the Unisphere for PowerMax REST documentation by navigating to a URL in your local instance of Unisphere for PowerMax. Navigate to ``https://{ip-address}:{port}/univmax/restapi/docs`` where ``{ip-address}`` is the IP address of your Unisphere server and ``{port}`` is the port it is listening on. PyU4V Version 10.0 ------------------ +-------------------------------+----------------------------+ | **Author** | Dell EMC | +-------------------------------+----------------------------+ | **PyU4V Version** | 10.0.0.0 | +-------------------------------+----------------------------+ | **Minimum Unisphere Version** | 10.0.0.0 | +-------------------------------+----------------------------+ | **Array Model** | VMAX-3, VMAX AFA, PowerMax | +-------------------------------+----------------------------+ | **Array uCode** | HyperMax OS, PowerMax OS | +-------------------------------+----------------------------+ | **Platforms** | Linux, Windows | +-------------------------------+----------------------------+ | **Python** | 3.6, 3.7, 3.8, 3.9 | +-------------------------------+----------------------------+ | **Requires** | Requests_, Six_, urllib3_ | +-------------------------------+----------------------------+ Note If you want to continue to use Unisphere 8.4.x or 9.0.x with PyU4V you will need to remain on PyU4V 3.1.x. There is no support for PyU4V 9.x with any version of Unisphere older than 9.1.x Note PyU4V version 9.x is compatible with scripts written for PyU4V versions >= 3.x, there is **zero** support or compatibility for PyU4V 2.x or earlier scripts in later versions of PyU4V. If you have scripts written which specifically target Unisphere REST 8.4, 9.0 or 9.1 endpoints these are still accessible via PyU4V 9.2.x however you will need to ensure you are passing the version required when performing these calls as PyU4V 9.2 will default to using 9.2 endpoints exclusively. You will also need to pay special attention to any REST JSON payloads in custom scripts as payloads are subject to change between major Unisphere REST releases. Installation ------------ Note A full installation guide can be found in PyU4V's ReadTheDocs_ which includes additional configuration options around PyU4V logging. PyU4V can be installed from source, via ``pip``, or run directly from the source directory. To clone PyU4V from source use ``git``:: $ git clone https://github.com/dell/PyU4V To install from source navigate into the new ``PyU4V`` directory and use ``pip``:: $ cd PyU4V/ $ pip install . Installing via ``pip`` without cloning from source can be achieved by specifying ``PyU4V`` as the install package for ``pip``:: $ pip install PyU4V # Install a specific version $ pip install PyU4V==10.0.0.0 Copy the sample ``PyU4V.conf`` provided with PyU4V to either your working directory or within a directory named ``.PyU4V`` in your current users home directory. The ``.sample`` suffix has to be removed for the configuration file to become valid for loading by PyU4V:: $ mkdir ~/.PyU4V $ cp PyU4V/PyU4V.conf.sample ~/.PyU4V/PyU4V.conf Note If ``PyU4V.conf`` is present in both the current working directory and the current user's home directory, the version of ``PyU4V.conf`` in the current working directory will take precedence. Edit PyU4V configuration settings in ``PyU4V.conf`` under the ``[setup]`` heading, these setting will need to reflect your environment configuration:: [setup] username=pyu4v-user password=secret-pass server_ip=10.0.0.75 port=8443 array=00012345678 verify=/path-to-file/server_hostname.pem Alternatively, you can pass some or all of these details on initialisation. Environment configuration values ``password``, ``username``, ``server_ip``, ``port``, and ``array`` **must** be set either in the config file or on initialisation. SSL verification as indicated by the ``verify`` key in ``PyU4V.conf`` is discussed in the next section. SSL CONFIGURATION ----------------- In order to enable SSL enabled communication between your host and the Unisphere server there are some additional steps required. First you must extract the CA certificate from Unisphere then either add it to the system certificate bundle or specify the path to the cert in ``PyU4V.conf``. We will demonstrate both approaches here. Get the CA certificate of the Unisphere server:: $ openssl s_client -showcerts -connect {server_hostname}:8443 \ </dev/null 2>/dev/null|openssl x509 -outform PEM > {cert_name}.pem # Example $ openssl s_client -showcerts -connect 10.0.0.75:8443 \ </dev/null 2>/dev/null|openssl x509 -outform PEM > unisphere91.pem Where ``{server_host_ip}`` is the hostname or IP address of your Unisphere server and ``{cert_name}`` is the name for your CA cert. This pulls the CA cert file from the instance of Unisphere at ``10.0.0.75:8443`` and saves it as a ``.pem`` file. To add the cert to a CA certificate bundle, copy the ``.pem`` file to the system certificate directory and update the CA certificate database:: # cp {cert_name}.pem /usr/share/ca-certificates/{cert_name}.crt # dpkg-reconfigure ca-certificates # update-ca-certificates Once the above steps are complete you will need to specify ``verify=True`` in ``PyU4V.conf`` for PyU4V to load the required Unisphere CA cert from the system certificate bundle:: [setup] verify=True Alternatively you can skip adding the certificate to a certificate bundle and pass it directly on PyU4V initialisation or specify the path to the certificate directly in ``PyU4V.conf``:: [setup] verify=/path/to/file/{cert_name}.pem Initialise PyU4V Connection --------------------------- Initialising PyU4V in your Python scripts is as simple as importing the library and initialising the connection (assuming you have ``PyU4V.conf`` configured as outlined in the previous section). .. code-block:: python import PyU4V conn = PyU4V.U4VConn() conn.common.get_unisphere_version() >> {'version': 'V10.0.0.0'} If you wish to query another array without changing the configuration file, call the connection ``set_array_id()`` function: .. code-block:: python conn.set_array_id('000197123456') The various types of functionality provided by PyU4V is separated into logical sections such as ``replication``, ``provisioning``, and ``performance``. For a full API breakdown by section and some usage example please refer to the PyU4V ReadTheDocs_. Support, Bugs, Issues --------------------- Please file support requests, bugs, and issues on the PyU4V GitHub-Issues_ page for this project. For further information on opening an issue and recommended issue templates please see the PyU4V ReadTheDocs_. For questions asked on StackOverFlow_, please tag them with ``Dell``, ``Dell EMC``, ``PowerMax``, and ``PyU4V`` to maximise the chances of the correct community members assisting. Contributing ------------ PyU4V is built to be used openly by everyone, and in doing so we encourage everyone to submit anything they may deem to be an improvement, addition, bug fix, or other change which may benefit other users of PyU4V. There are some requirements when submitting for PyU4V, such as coding standards, building unit tests and continuous integration tests, and going through a formal code review process, however anyone familiar with open source development will be familiar with this process. There are a number of core PyU4V reviewers and once a submission has approvals from two or more core reviewers and all tests are running cleanly then the request will be merged with the upstream PyU4V repo. For a full breakdown of contribution requirements, coding standards, submitting and everything else in between please refer to PyU4V ReadTheDocs_. Tools ----- Please refer to the Tools section of ReadTheDocs_ for OpenStack functionality to migrate volumes to the new REST masking view structure.
