This is a Client library that can talk to the HPE 3PAR Storage array. The 3PAR storage array has a REST web service interface and a command line interface. This client library implements a simple interface for talking with either interface, as needed. The python Requests library is used to communicate with the REST interface. The python paramiko library is used to communicate with the command line interface over an SSH connection.

This is the new location for the rebranded HP 3PAR Rest Client and will be where all future releases are made. It was previously located on PyPi at:

The GitHub repository for the old HP 3PAR Rest Client is located at:

The HP 3PAR Rest Client (hp3parclient) is now considered deprecated.


This branch requires 3.1.3 version MU1 or later of the 3PAR firmware. File Persona capabilities require 3PAR firmware 3.2.1 Build 46 or later.

Running Simulators

The unit tests should automatically start/stop the simulators. To start them manually use the following commands. To stop them, use ‘kill’. Starting them manually before running unit tests also allows you to watch the debug output.

  • WSAPI:

    $ python test/ -port 5001 -user <USERNAME> -password <PASSWORD> -debug
  • SSH:

    $ python test/ [port]

Building wheel dist

This client now supports building via the new python WHEELS standard. Take a look at

  • building:

    $ python bdist_wheel
  • building and uploading:

    $ python sdist bdist_wheel upload
