Automation in SAN Linux Host Utilities

Students Name: Paritosh Katyal

ID No: 2008A3PS213H

Station Name: NetApp

PS Faculty: Muthulakshmi Anandhanarayan



Problem Objectives

• To develop Automation test suites to be used byHost utilities team

•

To give insights on existing methods to makeautomation more robust

• To work on feature enhancement requeststhereby resulting in improved currency

predictability and quality of the OS release





Background and Significance

• The SAN LHU team comes up periodicallywith rectifications and optimized featuresimplementing storage solutions via test

suites for host OS releases

• Automation test suites are continuously

enhanced to support the new features inthe host OS releases



Methodology(1)

Problem:-

• There are some steps in a test suite that are usedrepeatedly

•

Manual intervention is time consuming for basic steps –

say, configuration on host side(any protocol)

Solution:-

A consistent approach to automation that includes

•Consistent libraries across all platforms

• Development and maintenance of tools that assist theHost SAN team



Methodology(2)

An example test suit is presented here

• There are some features that need to besupported on new OS releases.

• The features will be tested manually first,

then Automation requests are raised.



Methodology(3)

• A testing environment which followsconsistent test approaches viz. templatesfor libraries, perl modules is used.

• The environment hides configuration,firmware differences and provides auniform interface

• Testbeds have to be created in which perlscripts are used to start automation forlinux qualifications.



Current status of project andpost mid sem plan

• Finished automation to support some of the existingfeatures on a OS release which shares the packages ofanother OS.

• A feature in an existing test suite is not excluding someboot devices, so have to ensure that the selectionalgorithm performs as per need

• A new test case to automount the logical volumes needs

to be implemented, which is to be done using aninterface that supports basic functions such as setup,cleanup etc

• There are few more pending requests, which will be

assigned after the current assignments



Summary and conclusion

• Basic knowledge of SAN, perl scripting isbeing used to automate the test cases

• The automated test suites greatlydecrease the redundancy and assurebetter performance

• Greater currency predictability can beachieved by automating the manuallytested feature requests
