When configuring disk arrays, virtual tape libraries and other devices with FC HBA cards, it is often necessary to check the WWPN information of FC HBA cards for port addition, ZONE division and other operations. correctly checking the information of FC HBA cards is the premise to ensure smooth construction.

This article mainly introduces the methods of viewing FC HBA card information in the same system through the following three chapters:

L FC HBA card overview

L View the information of FC HBA card under Windows system

L View the information of FC HBA card under Linux system

Overview of FC HBA Card

FC HBA, also known as Fibre Channel Host Bus Adapter, fibre Channel host adapter, referred to as optical fiber adapter.

In FC network environment, hosts need to use an interface card when they need to connect with FC network and FC storage devices (SAN disk array), just as Ethernet card is needed to connect Ethernet. This interface card is called FC HBA, or FC HBA card for short.

Like the MAC address of the Ethernet card, there is a unique logo on HBA: WWN (World Wide Name), and there are two kinds of WWN on FC HBA:

① Node WWN (WWNN): each HBA has its own unique Node WWN

② Port WWN (WWPN): each port on each HBA card has its own unique Port WWN.

Because communication is done through port, you need to use WWPN instead of WWNN in most cases. The length of WWN is 8bytes, expressed in hexadecimal and separated by colons, for example: 50:06:04:81:D6:F3:45:42

View the information of FC HBA card under Windows system

QLOGIC and EMULEX are manufacturers of common FC HBA cards equipped with our products. The following is an introduction to how to view these two types of FC HBA cards under the Windows system.

In the Windows system, you can use the GUI interface management tool provided by the manufacturer to view and configure the FC HBA card, and the FC HBA card for QLOGIC and EMULEX can view and configure the related FC HBA card through SANSurfer and HBAnywhere respectively.

1 、 QLOGIC SANSurfer

SANSurfer GUI software for managing FC HBA cards allows you to modify other parameters such as FC HBA card rate and see detailed information about FC HBA cards. The download link provided on the official website is:

Http://driverdownloads.qlogic.com/QLogicDriverDownloads_UI/Product_detail.aspx?oemid=264

After obtaining the SANSurfer installation package, the internal files are shown in figure 1. Double-click start_here.htm to install the appropriate driver and graphical management software through the installation wizard:

Follow the wizard's prompts to complete the installation and use the SANSurfer management software to view and configure the FC HBA card.

In addition, during the post process of the Windows system, you can press "Ctrl+Q" as prompted by the system to configure the character mode of the Qlogic FC HBA card.

2 、 EMULEX HBAnywhere

HBAnywhere is a GUI software provided by EMULEX to manage EMULEX FC HBA cards, which can be downloaded free of charge on Huawei Symantec's official website. The link is as follows:

View the information of FC HBA card under Linux system

This section will use RedHat Linux AS4, RedHat Linux AS5, SuSe Linux 9, and SuSe Linux 10 as examples to describe how to view FC HBA card information in a Linux system.

Before viewing the FC HBA card, make sure that the FC HBA card is physically connected and the LEDs are good.

1. RedHat Linux AS4 and SuSE Linux 9

The method of viewing FC HBA card information in RedHat Linux AS4 is basically the same as that in SuSE Linux 9. Here we take RedHat AS4 as an example to introduce how to view FC HBA card information.

There are typically two files in the / proc/scsi/qla2xxx directory of RedHat AS4 or SuSE Linux 9 systems: 1, 2, or 3, 4, which contain the configuration information for the FC HBA card.

[root@localhost qla2xxx] # pwd

/ proc/scsi/qla2xxx

[root@localhost qla2xxx] # ls

2. RedHat Linux AS5 and SuSE Linux 10

The method of viewing FC HBA card information in RedHat Linux AS5 is basically the same as that in SuSE Linux 10. Here we will introduce how to view FC HBA card information in RedHat Linux AS5.

The / sys/class/fc_host/host*/port_name file of the RedHat AS5 system contains information about all FC HBA cards that have been discovered by the system. Use the View command to view the contents of the file to see the FC HBA card information.

View the information of FC HBA card under UNIX system

This paper introduces how to view FC HBA card information in UNIX system, which is widely used in practice, including IBM AIX, SUN SOLARIS and HP-UNIX.

1 、 IBM AIX

① to view fiber-optic devices connected to AIX hosts

# lsdev-Cc adapter-S a | grep fcs

Fcs0 Available 09-08 FC Adapter

Fcs1 Available 09-09 FC Adapter

The above output shows two fiber optic cards: fcs0 and fcs1.

② check the WWN number of the optical fiber card fcs0

# lscfg-vpl fcs0

In the output of the above command, the bold red part is the WWN number of the fiber card.

2 、 SUN SOLARIS

① queries existing storage devices and fiber optic devices, and you can read WWN numbers including disk devices.

# luxadm probe

When ② looks at the prot of HBA, you can get the port value and properties of HBA card.

# luxadm-e port

/ devices/pci@0,0/pci1022,7450@2/pci1077101@1/fp@0,0:devctl NOT CONNECTED

/ devices/pci@0,0/pci1022,7450@2/pci1077101@1,1/fp@0,0:devctl CONNECTED

You can see that only one optical fiber card is connected to the storage device.

③ selects the connected HBA card to check its WWN number

# luxadm-e dump_map / devices/pci@0,0/pci1022,7450@2/pci1077101@1/fp@0,0:devctl
