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.

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 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, then follow the driver instructions.
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.

When to select this option
When you want to change the unit attention (UA) from NOT READY to MEDIUM
ERROR during the pool-VOLs blockade.
When using General Parallel File System (GPFS) in the HP XP7 Storage

High Availability is used in the configuration with the data centers (Metro
configuration).
Hitachi Dynamic Link Manager is used as the alternative path software.
The host group is on the non-optimized path of Hitachi Dynamic Link
Manager.
The performance deterioration of I/O responses can be avoided without
I/O using the non-optimized path of Hitachi Dynamic Link Manager.
