HP XP P9500 Storage - Manual (Page 160)

The WWN is a unique identifier for a host bus adapter in an open-system host, consisting of 16
hexadecimal digits. The following topics describe how to find the WWN of a host on different
operating systems. It is best to make a record of the WWNs of the hosts in your storage system,
because you will need to enter these WWNs in LUN Manager dialog boxes to specify the hosts
used in your storage system.

Finding a WWN on Windows
HP supports the Emulex fibre channel adapter in a Windows environment, and will support other
adapters in the future. For further information on fibre channel adapter support, or when using a
fibre channel adapter other than Emulex, contact the HP Technical Support for instructions on
finding the WWN.
Before attempting to acquire the WWN of the 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 21 To find a WWN on Windows environment with an Emulex mini-port driver
1. Verify that the fibre channel adapters and the fibre channel device drivers are installed.
2. Log on to the Windows 2000 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.option.??6/15:
I do not have the Find/Files Folder options on my Windows Start menu. Where are you
talking about? Is this in an older/newer version of Windows?
2. On the Find dialog box, in Named type lputilnt.exe, and from the Look in list, choose the
hard 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, 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. 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.
Finding a WWN on Oracle Solaris
HP supports the JNI fibre channel adapter in an Oracle Solaris environment. This document will
be updated as needed to cover future adapter-specific information as those adapters are supported.
For further information on fibre channel adapter support, or if using a fibre channel adapter other
than JNI, contact HP Technical Support for instructions for finding the WWN.
Procedure 22 To find a WWN on Oracle Solaris
1. Verify that the fibre channel adapters and the fibre channel device drivers are installed.
2. Log on to the Oracle Solaris host with root access.
3. Type dmesg |grep Fibre to list the installed fibre channel devices and their WWNs.
4. Verify that the fibre channel adapters listed are correct, and record the listed WWNs.
