Appendix A Overview of CIM/WBEM
This appendix gives an overview of CIM/WBEM provided by Device Manager, and explains how to
set up CIM/WBEM.
A-1 Device Manager and CIM/WBEM
Device Manager supports WBEM defined by the standards-setting organization DMTF. WBEM is a
standard proposed by the DMTF for managing networked devices, including hosts and storage
subsystems, over the Internet. WBEM enables you to share data about devices in different
environments (such as environments with different vendors, operating systems, or protocols)
without considering the differences. WBEM is based on CIM, an object-oriented information model.
CIM, defined by DMTF, is a standardized approach for managing systems in network environments.
CIM provides a framework for expressing the data to be managed. Applying CIM to storage
subsystems enables you to use standardized methods to manage the configuration and status of
storage subsystems in networks.
The CIM models provided by Device Manager conform to the SMI-S specifications (SNIA-CTP(SNIA
Conformance Testing Program)) endorsed by SNIA (Storage Networking Industry Association). The
CIM models of the Device Manager server are defined in MOF (Managed Object Format) files
provided by Device Manager.
CIM clients can access Device Manager by using the CIM XML/HTTP interface defined by WBEM.
Figure A-1 shows the CIM components for Device Manager.

From a CIM client, you can specify a namespace by using the follow procedure:
• Specify the SMI-S version.
Specify root/smis/smisxx (xx is an abbreviation for the version number).
For example, to specify version 1.2.0, enter root/smis/smis12.
The latest namespaces that complies with the specified SMI-S version is selected.
• Specify the condition current.
Enter root/smis/current.
The current namespace is selected.
