You want to write custom workflows to perform disaster recovery operations for your environment in OnCommand Workflow Automation. In this scenario…

OnCommand Workflow Automation (WFA) enables the creation of custom commands to extend its automation capabilities. When defining a new command, WFA provides several implementation types, including SQL queries and scripts. For scripting, WFA natively supports the execution of both Perl and PowerShell. These languages are used to write the logic that interacts with NetApp systems (via toolkits like the Data ONTAP PowerShell Toolkit) or other infrastructure components to perform the custom operations required for tasks such as disaster recovery.

C. PHP: PHP is a server-side scripting language primarily designed for web development and is not a supported language for creating commands within OnCommand Workflow Automation.

D. Python: While Python is a common language for automation, OnCommand Workflow Automation does not provide native support for Python as a script type when creating commands.

1. NetApp OnCommand Workflow Automation 5.1 Development Guide:

Reference: Chapter 3, "Developing with WFA," Section: "Creating commands."

Content: This section explicitly lists the types of commands that can be created. It states, "You can create a command by using a SQL query, a PowerShell script, or a Perl script." This directly confirms that Perl and PowerShell are the supported scripting languages.

2. NetApp Technical Report TR-4420: OnCommand Workflow Automation Best Practices:

Reference: Section 3.2, "Commands," Page 10.

Content: The report discusses the building blocks of WFA and mentions, "WFA supports Perl and Microsoft PowerShell scripting languages for command definition." This reinforces that these two are the designated languages for custom script-based commands.
