VERSION: 1.2.10

A minimalist Python library to manage VNX/Unity systems.
This document lies in the source code and go with the release.
Check different release branch/tag for matched documents.

License
-------

`Apache License version 2`_

Install via PIP
---------------
You could use "pip" to install "storops".

.. code-block:: bash

    $ pip install storops

Make sure `naviseccli` is installed if you want to manage VNX.
Please contact with Dell/EMC support about installing the `NaviCli-Linux` rpm package.

Optional package requirement
````````````````````````````

#. `paramiko` package

The `paramiko` is required if you need to manage the VNX file related
resources. please follow `install paramiko <http://www.paramiko.org/installing.html>`_ install `paramiko`.

Install via RPM
---------------
There are two RPM packages in each release page.
- `python-storops-<version num>`, install this if you only manage Unity systems.
- `python-storops-vnx-<version num>-x86_64`, a virtual package depends on `python-storops` and `NaviCli-Linux`. Install this if you manage VNX systems or both.

You could download the rpm package from release download page, and install it via:

.. code-block:: bash

    $ rpm -i <python-storops_file>

Please contact with Dell/EMC support about installing the `NaviCli-Linux` rpm package.

Tutorial
--------

User may reference three kinds of classes directly.
All of them are available under the storops module.

- system classes: like VNXSystem and UnitySystem
- exceptions: like UnityException, VNXException, etc.
- enums: like VNXProvisionEnum, NFSTypeEnum, etc.

We recommend to try the library with IPython notebook or shell.

All operation/resource are accessed from the system instance.

Here are some examples of the typical usage:

Get the VNX System Instance
```````````````````````````
Use the vnx instance to access all sorts of resource and features.

.. code-block:: python

    # initialize the VNX system instance
    >>> from storops import VNXSystem
    >>> vnx = VNXSystem('10.1.1.1', 'sysadmin', 'password')
    >>> vnx
    {
        "VNXSystem": {
            "existed": true,
            "hash": 5339308,
            "name": "K10",
            "agent_rev": "7.33.8 (2.97)",
            "model_type": "Rackmount",
            "model": "VNX5800",
            "serial": "APM00123456789",
            "revision": "05.33.008.3.297"
        }
    }

Get the Unity System Instance
`````````````````````````````

.. code-block:: python

    from storops import UnitySystem
    unity = UnitySystem('<management ip>', '<user>', '<password>')

Get Resources from System or Other Resources
````````````````````````````````````````````

.. code-block:: python

    # get all pools
    >>> pools = vnx.get_pool()
    {
    "VNXPoolList": [
        {
            "VNXPool": {
                "luns": [
                    1,
                    0
                ],
                "status": "OK(0x0)",
                "current_operation_status": "N/A",
                ...
                "disks": {
                    "VNXDiskList": [
                        {
                            "VNXDisk": {
                                "private": {},
                                "clariion_tla_part_number": "005050344PWR",
                                "prct_bound": {},
    ...

Get a Resource
``````````````

Attention: you could still initialize the python object even
if the resource doesn't exists on array.
You could use the "existed" property to check the existance of the
resource.

.. code-block:: python

    # get a existing LUN
    >>> lun = vnx.get_lun(lun_id=1)
    >>> lun
    {
        "VNXLun": {
            "status": "OK(0x0)",
            "existed": true,
            ...
            "default_owner": "VNXSPEnum.SP_B",
            "name": "l0"
        }
    }

    # get a non-existing lun
    >>> vnx.get_lun(name='hello')
    {
        "VNXLun": {
            "existed": false,
            "hash": 5699430
        }
    }


Access Resource Properties
``````````````````````````
Each properties printed in the json output could be accessed directly.

.. code-block:: python

    # access resource properties
    >>> lun.status
    u'OK(0x0)'


Update the Resource Property
````````````````````````````

All properties of a resource will be updated if any of them is accessed.
For performance concern, the lib won't send query to array once properties
are initialized.
Explicitly call the *"update()"* function if you need a refresh.

.. code-block:: python

    >>> vnx = VNXSystem('10.1.1.3')     # no query to the system
    >>> vnx.model
    u'VNX5800'                          # send query, initialize all properties
    >>> vnx.name
    u'k10'                              # no query
    >>> vnx.update()                    # send query, update all properties


Executing Operations
````````````````````
Most of the create/modify operations can be found on the instance.
Call these instance methods to execute the operation.

.. code-block:: python

    # create lun
    >>> pool = pools[0]
    >>> lun1 = pool.create_lun('lun1', size_gb=2)

Remove a Resource
`````````````````

.. code-block:: python

    # delete a resource
    >>> lun1.delete()

Getting metrics
```````````````
- VNX

.. code-block:: python

    >>> from storops import VNXSystem
    >>> vnx = VNXSystem('<management ip>', '<user>', '<password>')
    # Enable metric query
    >>> vnx.enable_perf_stats()
    # Get iops for Storage Processor
    >>> sp = vnx.get_sp()[0] 
    >>> sp.read_iops
    0.0
    >>> sp.write_iops
    0.6666666666666666
    >>> sp.read_size_kb
    0.0
    >>> sp.write_size_kb
    4.2250000000000005

    
- Unity

.. code-block:: python

    >>> from storops import UnitySystem
    >>> unity = UnitySystem('<management ip>', '<user>', '<password>')
    # Enable metric query
    >>> unity.enable_perf_stats()
    # Once metric query enabled, storops will pull the realtime metric info
    # from Unity periodically and calculate them, the default interval is
    # 60s, so suggest to wait more than 60s for the first time calculation
    >>> import time; time.sleep(60)
    # Get iops, bandwidth for lun
    >>> lun1 = unity.get_lun()[0]
    >>> lun1.read_iops
    0.05
    >>> lun1.total_iops
    0.05
    >>> lun1.write_iops
    0
    >>> lun1.read_byte_rate
    25.6
    >>> lun1.write_byte_rate
    0
    >>> lun1.total_byte_rate
    25.6

Getting Help
````````````

- If you are using IPython, use "?" to check the document and
  method signature.

.. code-block::

    >>> pool.create_lun?
    Signature: pool.create_lun(lun_name=None, size_gb=1, lun_id=None,
               provision=None, tier=None, ignore_thresholds=None)
    Docstring: Create a pool LUN in the pool.
    File:      c:\work\python\storops\storops\vnx\resource\block_pool.py
    Type:      instancemethod

-  In IPython, use tab to check all extrinsic methods/properties
   of the resource.  Print the resource to check all intrinsic properties.

.. code-block::

    >>> vnx.
    vnx.control_station_ip           vnx.get_property_key             vnx.parse_all
