About the CIM Extension for Windows
The CIM Extension for Windows gathers information from the operating system and host bus
adapters. It then makes the information available to the management server. It plugs into Windows
Management Instrumentation (WMI), and thus, the CIM Extension is not a separate process.
Microsoft created WMI as its implementation of Web-based Enterprise Management (WBEM). For
more information about WMI, refer to the Microsoft Web site at http://www.microsoft.com.
Keep in mind the following:
• Install the CIM Extension on each host.
• The installation restarts WMI to make it aware of the CIM Extension. Services or applications
using WMI are shut down. You will need to restart those applications manually. For example,
Microsoft Exchange System Manager uses the Microsoft Exchange Management service, which
depends on WMI. After the installation, you need to start the Microsoft Exchange Management
service so that Microsoft Exchange System Manager becomes available. It is strongly
recommended that before you install the CIM Extension, make note of services and applications
using WMI. If you are not aware of the applications using WMI, see ”Finding Applications
Dependent on WMI” on page 186.
• The CIM Extension starts automatically whenever the system is restarted.
• If the Windows host has an Emulex LP9000-class host bus adapter (HBA), make sure you have
the latest windows drivers for the HBA from the Emulex Web site at
http://www.emulex.com. Follow the instructions that are provided on the Web site.
The CIM Extension communicates with an HBA by using the Host Bus Adapter Application
Programming Interface (HBAAPI) created by the Storage Network Industry Association (SNIA).
Some HBA vendors register their HBA drivers with the HBAAPI through the Windows registry. The
management server only supports HBA communication with HBAs that are compliant with the
HBAAPI. For more information about the HBAAPI, see the following Web page at the SNIA Web
Site: http://www.snia.org/tech_activities/hba_api/
