Reference Guide

1. Log in to the edge switch to which the device is connected.
2. Assign the FA-PWWN.
∙ If you are manually assigning a WWN, enter the following command:
fapwwn --assign -port [slot/]port -v Virtual_PWWN
∙ If you want the WWN to be automatically assigned, enter the following command:
fapwwn --assign -port [slot/]port
3. Display the FA-PWWN.
fapwwn --show -port all
You should see output similar to the following sample. The FA-PWWNs are in the VPWWN column.

4. Display the FA-PWWN on the HBA.
The following steps are to be executed on the server and not the switch.
a) Log in to the server as root.
b) Enter the following command to display the FA-PWWN.
# bcu port --faa_query port_id
FAA state: Enabled
PWWN: 11:22:33:44:33:22:11:22
PWWN source: Fabric
The HBA retains the FA-PWWN until it is rebooted. This means you cannot unplug and plug the cable into a different port
on the switch. You must reboot the HBA before moving the HBA to a different port.
If you move an HBA to a different port on a switch running Fabric OS v7.0.0 or later, the HBA will disable its port. The port
remains disabled even if you then move the HBA to a port on a switch running a version of Fabric OS earlier than 7.0.0.
