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 18 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.
The following is an example of finding a WWN on Oracle Solaris.
# dmesg |grep Fibre <- Enter the dmesg command.
:
fcaw1: JNI Fibre Channel Adapter model FCW
fcaw1: Fibre Channel WWN: 200000e0694011a4 <- Record the WWN.
fcaw2: JNI Fibre Channel Adapter model FCW
fcaw2: Fibre Channel WWN: 200000e06940121e <- Record the WWN.

Finding a WWN on AIX, IRIX, or Sequent
To find the WWN in an IBM AIX, SGI Irix, or Sequent environment, use the fabric switch that is
connected to the host. The method of finding the WWN of the connected server on each port using
the fabric switch depends on the type of switch. For instructions on finding the WWN, see the
manual of the corresponding switch.
Finding WWN for HP-UX
To find the WWN in an HP-UX environment:
1. Verify that the Fibre Channel adapters and the Fibre Channel device drivers are installed.
2. Log in to the HP-UX host with root access.
3. At the command line prompt, type:
/usr/sbin/ioscan -fnC lan
This will list the attached Fibre Channel devices and their device file names. Record the Fibre
Channel device file name (for example, /dev/fcms0).
NOTE: When the A5158 Fibre Channel adapter is used, at the command line prompt, enter
/usr/sbin/ioscan -fnC fc for the device name.
4. Use the fcmsutil command along with the Fibre Channel device name to list the WWN
for that Fibre Channel device. For example, to list the WWN for the device with the device
file name /dev/fcms0, type:
/opt/fcms/bin/fcmsutil /dev/fcms0
Record the Fibre Channel device file name (for example, /dev/td0).
