Find WWN of the host bus adapter

Before physically attaching the storage system to hosts, some preparation work needs to be performed. When configuring a fibre channel environment, first verify that the fibre adapters and the fibre channel device drivers are installed on the open-system hosts. Next, find the World Wide Name (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 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.
