AIX:

1. Obtain the fiber optic devices connected to the AIX host:

# lsdev-Cc adapter-S a | grep fcs

Fcs0 Available 09-08 FC Adapter

Fcs1 Available 09-09 FC Adapter

Among them, there are two fiber optic cards .fcs0 and fcs1.

2. Check the WWN number of the fiber card.

HP-Unix:

1. List the fiber card devices connected to the HP computer:

As you can see from this figure, / dev/fcd0 and / dev/fcd1 are two optical fiber cards

2. Check the WWN number of the fiber card.

The red part shows the WWNN and WWPN numbers of the HBA card, as well as the WWN number of the fiber switch port to which the HBA card is connected.

Solaris:

Luxadm commands are used on solaris to manage storage devices and fiber optic related devices.

1. If you query existing storage devices and fiber optic devices, you can read the WWN number including disk devices.

# luxadm probe

2. Check the prot of HBA to get the port value and connection 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. Select the connected HBA card and check its WWN number

Format: # luxadm-edump_map device port. The port value can be obtained from step 2. The following figure is shown:

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

Pos Port_ID Hard_Addr Port WWN Node WWN Type

000 210000e08b19827a 200000e08b19827a 0x1f (Unknown Type,Host Bus Adapter)

Redhat:

In Redhat, device management information is stored in the kernel, the / proc directory. So we generally query CPU, memory, disk and other information, also in this directory. The HBA card-related information is stored in the / proc/scsi/qla2300/ directory, and different devices correspond to different file names, such as

# grep scsi/ proc/scsi/qla2300/1

Number of reqs in pending_q= 0, retry_q= 0, done_q= 0scissors retrycles Q = 0

Scsi-qla0-adapter-node=200000e08b9cf661

Scsi-qla0-adapter-port=210000e08b9cf661

You can find the WWNN and WWPN numbers of the first HBA card in the system.

Node WWN and Port WWN in HBA card

HBA, literally means host bus adapter. I think it is now called FC HBA in a narrow sense, and the HBA is Fibre Channel HostBus Adapter, because the network card can also be called NETWORK HBA. In FC networks, hosts (such as servers) need to use an interface card when they need to connect with FC networks and FC storage devices (such as SAN), just as Ethernet cards are needed to connect to Ethernet. This kind of interface card is called FC HBA, or HBA for short.

Like the MAC address of the Ethernet card, there is a unique identity on the HBA, which is WWN (World Wide Name). There are two types of WWN on HBA:

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

It is usually used in solaris

# luxadm probe

All the results are NODE WWN. Based on how many NODE WWN you have, you will know how many FC HBA cards you have.

Port WWN (WWPN): each port on a 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 the WWN is 8bytes, represented in hexadecimal and separated by colons. For example: 50:06:04:81:D6:F3:45:42

The method of viewing FC HBA Card Information

When configuring disk array or virtual tape library, it is often connected with the host through FC interface, so it involves the viewing of FC HBA card. This paper summarizes and collates this problem.

I. Windows system

In the Windows system, you can use the management software provided by the FC HBA card manufacturer to view the WWN number of the optical adapter, as follows:

Qlogic:SANsurfer

Emulex:HBAnyware

II. SuSE Linux 9

Look at the contents of the / proc/scsi/qla2xxxport_name file to see the WWN information of the corresponding FC HBA card:

# cat/sys/class/fc_host/host*/port_name

0x210000e08b907955

0x210000e08b902856

IV. RedHat Linux AS4

# grep scsi/ proc/scsi/qla2xxx/3

Number of reqs in pending_q= 0, retry_q= 0, done_q= 0, scsi_retry_q= 0

Scsi-qla0-adapter-node=20000018822d7834

Scsi-qla0-adapter-port=21000018822d7834

Scsi-qla0-target-0=202900a0b8423858

Scsi-qla0-port-0=200800a0b8423858:202900a0b8423858:0000e8:1

5. RedHat Linux AS5

# cat/sys/class/fc_host/hostx/port_name

VI. Solaris 10

The fcinfo command is provided to view the WWN information of FC HBA using fcinfohba-port:

# fcinfo hba-port

View the path and connection status of the fiber card port:

# luxadm-e port

View the WWN of the port:

# luxadm-e dump_mapfibre_channel_HBA_port / / output of the previous command

# prtconf-vp | grep-I wwn

# prtpicl-v | grep-I wwn (prtpicl-print PICL tree)

VI. HP-UX

# ioscan-funCfc / / find HBA card, and then use fcmsutil to view HBA card information

# fcmsutil / dev/fcd0 (1)

7. AIX

# lsdev-Ccadapter / / find the HBA card

# lscfg-vpl fcs0 | grep network address

Note:

The first number of Emulex's HBA's WWN is 1.

The first number of Qlogic's HBA's WWN is 2.

The first number of HP Tachyon HBA's WWN is 5

Qlogic parameter

Connection Options

0-Loop only

1-Point-to-point only

2-Loop preferred,otherwise point-to-point.

As recommended by the server, select loop only when DAS is directly connected to storage and point-to-point only when connecting storage through a fibre switch

Data Rate

This configuration item defines the FC port rate

0-1Gb/s

1-2Gb/s
