About the Script Commands
You can use the script commands to configure and manage a storage array. The script
commands are distinct from the command line interface (CLI) command wrappers.
You can enter individual script commands, or you can run a file of script commands.
When you enter an individual script command, you embed the script command in a
CLI command wrapper. When you run a file of script commands, you embed the file
name in the CLI command wrapper. The script commands are processed by a script
engine that performs the following functions:

Verifies the command syntax

Interprets the commands

Converts the commands to the appropriate protocol-compliant commands

Passes the commands to the storage array
At the storage array, the storage array controllers run the script commands.
The script engine and the script commands support the storage array configuration
and management operations that are listed in the following table.
