Finding a WWN on a Windows host

Emulex Fibre Channel adapters are supported in a Windows environment. For further information about Fibre Channel adapter support, or when using a Fibre Channel adapter other than Emulex, contact Hitachi Solution Support Center for instructions on finding the WWN.

Before attempting to acquire the WWN of an Emulex adapter, confirm whether the driver installed in the Windows 2000 or Windows Server 2003 environment is an Emulex port driver or an Emulex mini-port driver, and then follow the driver instructions.

Procedure

  1. Verify that the Fibre Channel adapters and device drivers are installed.

  2. Log on to the Windows host with administrator access.

  3. Go to the LightPulse Utility to open the LightPulse Utility window. If you do not have a shortcut to the utility:

    1. Go to the Start menu, select Find and choose the Files and Folders option.

    2. On the Find dialog box, in Named type lputilnt.exe, and from the Look in list, choose the data drive that contains the Emulex mini-port driver.

    3. Choose Find Now to search for the LightPulse utility.

      If you still cannot find the LightPulse utility, contact Emulex technical support.

    4. Select lputilnt.exe from the Find: Files named list, and then press Enter.

  4. On the LightPulse Utility window, verify that any installed adapters appear in the tree.

  5. In the Category list, choose the Configuration Data option.

  6. In the Region list, choose the 16 World-Wide Name option. The WWN of the selected adapter appears in the list on the right of the window.
