Overview

This is a collection of storage disk commands.

At the moment, the current version is supporting some commands of EMC VMAX Storage.

Requirements

  • Python >=2.7

Install

  • Using PIP:
$ pip install PyStorage
  • Offline install

Download the package on https://pypi.python.org/pypi/PyStorage/

$ tar xvzf PyStorage-X.Y.tar.gz
$ cd PyStorage-X.Y
$ python setup.py install

Using

EMC.VMAX

It’s works with Storage Disk EMC VMAX.

  • Importing and initializing
>>> import pystorage
>>> symcli_path = '/opt/emc/SYMCLI/bin'
>>> my_vmax = pystorage.EMC.VMAX(symcli_path)
  • EMC.list()

List all Storages Disk available.

returns array [return code, output]

>>> print my_vmax.list()[1]
