Welcome to PyU4V’s documentation!


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.


You can get the Unisphere for PowerMax REST documentation by navigating to https://developer.dell.com/apis/4458/ An OpenApi.json file can be download from this site for use with tools like PostMan or for interfacing with PyU4V custom API call mechanism. Please refer to this documentation when looking for information about query path parameters for functions that accept them.

Build your own PyU4V Docs

PyU4V docs have been built using Sphinx and included with the source PyU4V package, however if you would like to build the docs from scratch use the following commands:

$ pip install sphinx
$ pip install sphinx-rtd-theme
$ cd PyU4V/docs
$ make clean && make html

All of the necessary make files and sphinx configuration files are included with PyU4V so you can build the docs after the required dependencies have been installed.

Once the above commands have been run you will find newly generated html files within the /PyU4V/docs/build folder. Open index.html within a browser of your choosing to view the docs offline. Generating the docs is not required, we have bundled the most up-to-date docs with PyU4V so you can still navigate to /PyU4V/docs/build/index.html within your browser to view PyU4V docs offline.
