Script Command StructureAll script commands have the following structure:command operand-data {statement-data}where, command identifies the action to be performed, operand-data represents the storage arraycomponent to configure or manage (such as a RAID controller module, physical disk, or disk group), andstatement-data is what you want to do to the component (such as, specifying the RAID level oravailability 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 identifiersNOTE: You can use any combination of alphanumeric characters, hyphens, and underscores for thenames. Command names can have a maximum of 30 characters. If you exceed the maximumcharacter 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 allobjects 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. Aqualifier 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.Table 5.
