4. Verify that the listed Fibre Channel adapters are correct, and record the listed WWNs.
Finding WWNs in AIX, SGI Irix, or Sequent environments
To find WWNs in AIX, SGI Irix, or Sequent environments, use the fibre switch connected to the host. The
method for finding the WWN of the connected server on each port using the fibre switch depends on the
type of switch. For instructions on finding the WWN, see the fibre switch's documentation.
Finding WWNs in HP-UX environments
1. Verify that the fibre adapters and Fibre Channel device drivers are installed.
2. Log in to the HP-UX host with root access.
3. At the command line prompt, enter:
/usr/sbin/ioscan -fnC lan
4. A list of attached Fibre Channel devices and their device file names appears.
# /usr/sbin/ioscan -fnC lan ← Enter the ioscan command.

Record the Fibre Channel device file name (for example, /dev/fcms0).
5. Use the fcmsutil command with the Fibre Channel device name to list the WWN for that

/dev/fcms0, enter:
/opt/fcms/bin/fcmsutil /dev/fcms0
