Finding WWNs
If you are configuring a Fibre Channel environment, you must verify that Fibre Channel adapters
and Fibre Channel device drivers are installed on the open-system hosts. Next, you must find the
WWN of the host bus adapter that is 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 section describes how to find the WWN of a host. 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
dialog boxes to specify the hosts used in your system.
Finding WWN for Windows NT or Windows 2000
HP currently supports the Emulex Fibre Channel adapter in a Windows NT or Windows 2000
environment, and will support other adapters in the future. For further information on Fibre Channel
adapter support, or if you are using a Fibre Channel adapter other than Emulex, contact HP
technical support for instructions on finding the WWN.
