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.
- After you install the adapter and you restart the host system, view the /var/adm/messages file.
- Search for the line that contains the applicable phrase for your host bus adapter (HBA):
- 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). - 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. - For the QLogic QLA2200F HBA, search for
qla2200-hbax-adapter-port-name
where x is the adapter number (0, 1, and so on).
- For the JNI SBUS HBA, search for
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.
To locate the WWPNs for the host, complete the following steps:
- Open the VMware Management Interface and click the Options tab.
- Select Storage Management.
- 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.
- Restart the server.
- Type the
scsiha -w [bus_number | device]
command.For example, typescsiha -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 #
