Fibre Channel port-name identification

The locations of port names are identified for Fibre Channel connections.

About Fibre Channel port-name identification

The format and content of the Fibre Channel (FC) port identifier are determined by the manufacturer of the link control facility for the applicable Fibre Channel port. The identifier is an eight-byte field, which the Fibre Channel protocols use to uniquely identify the Fibre Channel port.

The worldwide port name (WWPN) consists of 16 hexadecimal characters (0 - 9 and A - F). The system uses the WWPN to uniquely identify the Fibre Channel host interface adapter that is installed in your host. The system automatically finds the WWPN for your host Fibre Channel host interface adapter when you attach your host to the system.
Note: Each Fibre Channel port has a unique WWPN. There are 1 or more ports per host interface adapter, and therefore 1 or more WWPNs per host interface adapter. Each host interface adapter port has a unique WWPN that must be added to the host object.

Locating the WWPN for an IBM System p, eServer, or an RS/6000 AIX host

You can locate the WWPN for an IBM® System p, eServer, or an RS/6000 AIX® host by completing the following steps:
  1. Log in as root.
  2. Type lscfg -vl fcsx, where x is the adapter number.

    The network address is the Fibre Channel adapter port WWPN value.

Locating the WWPN for a host that is running the Linux operating system

You can locate the WWPN for a host that is running the Linux® operating system with a QLogic adapter by completing the following steps.

Procedure
  1. Restart the server.
  2. Press Alt+Q to get the FAST!Util menu.

    If you have more than one Fibre Channel host bus adapter (HBA) installed, all the Fibre Channel HBAs are displayed. Scroll down to the adapter you want. Press Enter.

  3. From the FAST!Util menu, scroll down and select Select Host Adapter.
  4. Scroll up and highlight Configuration Settings. Press Enter.
  5. From the Configuration Settings menu, click Host Adapter Settings.
  6. Write down the 16-digit alphanumeric string that is displayed.

Locating the WWPN for a host running the Microsoft Windows operating system

Determining the WWPN of a host that runs a Windows operating system depends on the type of HBA in your host server.

For QLogic, you can use the SANsurfer GUI/IBM FAStT Management Suite Java™ (MSJ) if you have it, or restart the host and enter Ctrl+Q to open the QLogic BIOS, where you can find the HBA WWPNs.

For Emulex hosts, use the elxcfg tool that is packaged with the firmware. This tool opens in the Windows operating system and does not require a restart.

Locating the WWPN for an Oracle SPARC host

You can locate the worldwide port name (WWPN) for an Oracle SPARC host by following the steps in this topic.

Procedure
  1. After you install the adapter and you restart the host system, view the /var/adm/messages file.
  2. Search for the line that contains the applicable phrase for your host bus adapter (HBA):
    1. For the JNI SBUS HBA, search for fcawx: Fibre Channel WWNN, where x is the adapter number (0, 1, and so on). You can find the WWPN on the same line immediately after the worldwide node name (WWNN).
    2. For the JNI PCI HBA, search for fca-pcix: Fibre Channel WWNN, where x is the adapter number (0, 1, and so on). You can find the WWPN on the same line as the WWNN.
    3. For the QLogic QLA2200F HBA, search for qla2200-hbax-adapter-port-name where x is the adapter number (0, 1, and so on).

Locating the WWPNs for a host that is running a VMware operating system

You can locate the worldwide port names (WWPNs) for a host that is running a VMware operating system.

Procedure

To locate the WWPNs for the host, complete the following steps:

  1. Open the VMware Management Interface and click the Options tab.
  2. Select Storage Management.
  3. In the new window, click the Adapter bindings tab.
    The WWPN is listed at the end of each port heading line, which is the lines that start with vmhba. For example, in the following line, 21:00:00:E0:8B:1A:E4:C6 is the WWPN of the HBA port: 
    vmhba0: QLogic Corp QLA231x/2340 (rev 02) (21:00:00:E0:8B:1A:E4:C6)

Locating the WWPN for an SGI Origin host

You can locate the WWPN for an SGI Origin host that is running the IRIX operating system with a QLogic adapter by following the steps.

  1. Restart the server.
  2. Type the scsiha -w [bus_number | device] command.
    For example, type scsiha -w 6 7 8 9. shows an example of the command output. 
    # scsiha -w 6 7 8 9
6 Portname: 210000e08b05d207
7 Portname: 210000e08b04d539
8 Portname: 210000e08b050808
9 Portname: 210000e08b038fe6
