VERSION: 1.2.11
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.
You could use "pip" to 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.
- paramiko package
The paramiko is required if you need to manage the VNX file related resources. please follow install paramiko install paramiko.
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:
Please contact with Dell/EMC support about installing the NaviCli-Linux rpm package.

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:
Use the vnx instance to access all sorts of resource and features.
# 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"
}
}
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.
Each properties printed in the json output could be accessed directly.
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.
Most of the create/modify operations can be found on the instance. Call these instance methods to execute the operation.
- VNX
>>> 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
>>> 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
- If you are using IPython, use "?" to check the document and method signature.
>>> 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.
