Hi Prakash,
There are a number of options, you can use the Data ONTAP powershell toolkit to automate deployment and configuration assuming you are working in windows environment.
You can download it here:

Alternately if you working in a UNIX environment and you need to write scripts in Perl or Ruby you can download the NMSDK here:

However rather than developing "scripts" you might also consider developing workflows that can invoked via a REST API using OnCommand Workflow Automation (WFA)
You can download WFA here:
http://mysupport.netapp.com/NOW/download/software/ocwfa/4.0/ (windows)
http://mysupport.netapp.com/NOW/download/software/ocwfa_linux/4.0/ (Linux)
WFA includes a number of example workflows to deploy vservers and provision NAS workloads. Optional content downloads are available via the automation store here:

You can also use API services

There are multiple options, your choice really depends on your requirements.
