Hardware Inventory Classes
The SMS Hardware Inventory Classes are generated dynamically based on the content of the Sms_def.mof file. Not all hardware classes and properties listed in the MOF file are reported. Each class and property in the MOF file contains an SMS_Report qualifier that specifies whether the class or property is reported — only those classes and properties with a value of TRUE are reported (dynamically generated). For information on changing the reporting value, see Enabling the Report Feature for Existing Classes and Properties.
During the hardware inventory process, the name for the class is transformed from Win32_hardware to SMS_G_System_hardware. For example, Win32_Account translates to SMS_G_System_Account. Each class in the Sms_def.mof file contains an SMS_Class_ID class qualifier that specifies the actual hardware name used by SMS.
In addition to the class name change, the following differences are found between the Win32 classes and the SMS hardware classes:
- Each SMS hardware class inherits four additional properties from SMS_G_System_Current.
- The SMS hardware classes do not support the Win32 class methods.
- Many of the SMS hardware classes contain a subset of the Win32 class properties.
Most of the definitions for the following SMS hardware classes are contained in the WMI Win32 classes documentation except for SMS_G_System_PC_ANALYSER, SMS_G_System_SYSTEM, and SMS_G_System_WORKSTATION_STATUS, which are not part of the Win32 class schema.
