CIM Reference Guide

The property values being presented could be NULL or empty string on some systems, although in

general, some non-empty values can be expected. Key properties (listed below) always carry non-empty

values. It is recommended that you use only the following properties as key attributes:

• CIM_PhysicalElement: CreationClassName, Tag

• CIM_System: CreationClassName, Name

• CIM_LogicalDevice: SystemCreationClassName, SystemName, CreationClassName, DeviceID

• CIM_Dependency: Antecedent, Dependent

• CIM_SoftwareElement: Name, Version, SoftwareElementState, SoftwareElementID,

TargetOperatingSystem

• CIM_SoftwareFeature: IdentifyingNumber, ProductName, Vendor, Version, Name

• CIM_IRQ: CSCreationClassName, CSName, CreationClassName, IRQNumber

• CIM_MemoryMappedIO: CSCreationClassName, CSName, CreationClassName, StartingAddress

• CIM_DMA: CSCreationClassName, CSName, CreationClassName, DMAChannel

• CIM_RedundancyGroup: CreationClassName, Name

• DELL_EsmLog: RecordNumber

• DELL_PostLog: RecordNumber

• DELL_BIOSExtensions: systemBIOSCharacteristics

• DELL_BIOSSettings: DisplayName

• CIM_ServiceAccessPoint: SystemCreationClassName, SystemName, CreationClassName, Name

Base Classes

The classes listed in the Server Administrator CIM provider class hierarchy do not have a parent property.

These base classes do not derive from another class. The base classes are:

• CIM_ManagedSystemElement

• CIM_Dependency

• DELL_EsmLog

• DELL_PostLog

• DELL_CMApplication

• DELL_CMDevice

• DELL_CMDeviceApplications

• DELL_CMInventory

• DELL_CMOS

• DELL_CMProductInfo

The CIM_ManagedSystemElement class is the base class for the system element hierarchy from which all

other CIM classes are derived. As a result, CIM_ManagedSystemElement has no parent. Examples of

managed system elements include software components such as files, devices such as hard drives and

controllers, and physical subcomponents of devices such as chip sets and cards. For the

CIM_ManagedSystemElement properties, see Caption, CreationClassName, Description, Name, and

Status in Common Properties of Classes

The Dell-defined classes are not defined in the official schema by the DMTF, the industry group that

defines the standards for CIM, and hence do not have parent classes. CIM_Dependency does not have a

parent class because it is a relationship or association between two managed system elements.
