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.

Table 1. Object Types and Identifiers
Object Type	Identifier
RAID controller	0 or 1
physicalDisk	Enclosure ID and the slot ID
physicalDiskChannel	Physical disk channel identifier
GroupName	Remote Replication virtual disk user label
host	User label
hostChannel	Host channel identifier
hostGroup	User label
hostPort	User label
snapVirtualDiskName	Virtual disk user label
snapshot	Virtual disk user label
snapGroup	A snapshot group contains a sequence of snapshot images of an associated base virtual disk. A snapshot group has a repository virtual disk that is used to save data for all of the snapshot images that are part of the snapshot group.
snapGroupName	Virtual disk group user label
storageArray	Not applicable
enclosure	Enclosure ID
virtualDisk	Virtual disk user label or the World Wide Identifier (WWID) for the virtual disk (set command only)
virtualDiskCopy	Target virtual disk and, optionally, the source virtual disk user labels
diskGroup	Virtual disk group number

Statement data is in the form of attribute=value (such as raidLevel=5), an attribute name (such as batteryInstallDate), or an operation name (such as consistencyCheck).
