Script Command Structure
All script commands have the following structure:
command operand-data {statement-data}
where, command identifies the action to be performed, operand-data represents the storage array
component to configure or manage (such as a RAID controller module, physical disk, or disk group), and
statement-data is what you want to do to the component (such as, specifying the RAID level or
availability of a disk group).
The general form of the syntax for operand-data is as follows:
(object-type | allobject-types | [qualifier]
(object-type [identifier] {object-type
[identifier]} | object-types [identifier-list]))
An operand-data object can be identified four ways:
• The object types and object qualifiers
• The all parameter
• Brackets
• A list of identifiers
NOTE: You can use any combination of alphanumeric characters, hyphens, and underscores for the
names. Command names can have a maximum of 30 characters. If you exceed the maximum
character limit, replace square brackets ([ ]) with angle brackets (< >) to overcome this limitation.
Use an object type when the command is not referencing a specific object. The all parameter means all
objects of the specified type in the storage array (for example, allVirtualDisks).
To perform a command on a specific object, use brackets to identify the object (for example,
virtualDisk[engineering]). Specify a subset of objects with a list of identifiers in brackets (for example,
virtualDisks[sales engineering marketing]). In a list of identifiers, use a blank space as the delimiter. A
qualifier is necessary if you want to include additional information to describe the objects.
The following table lists the object type and identifiers associated with the object types.
