6 Finding an open-system host's
World Wide Name (WWN)
If you are configuring a Fibre Channel environment, you must verify that the fibre adapters and Fibre
Channel device drivers are installed on the open-system hosts. Next, you must find the World Wide
Name (WWN) of the host bus adapter used in each open-system host. The WWN is a unique identifier
for a host bus adapter in a open-system host, consisting of 16 hexadecimal digits.
This chapter describes how to find a host's WWN. HP recommends that you make a record of WWNs
of the hosts in your system, because you will need to enter WWNs in LUN Manager panes to specify
the hosts used in your system.
Finding WWNs in Windows NT or Windows 2000
environments
HP currently supports the Emulex Fibre Channel adapter in Windows NT or Windows 2000 environments,
and will support other adapters in the future. For more information about Fibre Channel adapter
support, or if you are using a Fibre Channel adapter other than Emulex, contact you HP account support
representative for instructions on finding the WWN.
NOTE:
Although these instructions are written for a Windows NT environment, similar instructions apply in a
Windows 2000 environment.
1. Verify that the fibre adapters and the Fibre Channel device drivers are installed.
2. Log in to the Windows NT or Windows 2000 host with administrator access.
3. Go to the LightPulse™ Utility to open the LightPulse Utility/NT pane.
