Linux下查看FC HBA信息

查看FC HBA卡信息的方法

在配置磁盘阵列或虚拟磁带库时，往往会以FC接口与主机对接，那么就涉及FC HBA卡的查看，本文就这个问题进行了总结与整理。

一、Windows 系统

在Windows系统中，可以使用FC HBA卡厂家提供的管理软件查看光纤适配器的WWN号码，具体如下：

Qlogic：SANsurfer

Emulex：HBAnyware

二、SuSE Linux 9

查看 /proc/scsi/qla2xxx/* ，并以 adapter-port 为关键字过滤即可查看FC HBA卡的WWN信息：

# cat /proc/scsi/qla2xxx/* | grep adapter-port

scsi-qla0-adapter-port=21000018822c8a2c;

scsi-qla1-adapter-port=21000018822c8a2d;

三、SuSE Linux 10

查看 /sys/class/fc_host/host*/port_name 文件的内容即可看到对应FC HBA卡的WWN信息：

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

0x210000e08b907955

0x210000e08b902856

四、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;

五、RedHat Linux AS5

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

六、Solaris 10

提供了fcinfo命令，可以使用 fcinfo hba-port 查看FC HBA的WWN信息：

# fcinfo hba-port

查看光纤卡端口的路径及连接状态:

# luxadm -e port

查看端口的WWN：

# luxadm -e dump_map fibre_channel_HBA_port // 上一命令的输出

# prtconf –vp | grep -i wwn

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

六、HP-UX

# ioscan –funC fc // 找到HBA卡，再用fcmsutil查看HBA卡信息

# fcmsutil /dev/fcd0(1)

七、AIX

# lsdev -Cc adapter // 找出HBA卡

# lscfg –vpl fcs0 |grep network address

备注：

Emulex的HBA的WWN的第一个数字为1

Qlogic的HBA的WWN的第一个数字为2

HP Tachyon HBA的WWN的第一个数字为5

Qlogic参数

Connection Options

0 - Loop only

1 - Point-to-point only

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

按服务器那边的建议，DAS直连存储时选择loop only，通过光纤交换机连接存储时选择point-to-point only

Data Rate

该配置项定义FC端口速率

0 - 1Gb/s

1 - 2Gb/s

2 - Auto

linux 下查看hba卡的wwn号

.HBA卡信息查询

/sys/class/fc_host/hostx/port_name 或node_name HBA卡的WWN号。

symbolic_name HBA卡型号

speed HBA卡速度

port_state HBA卡状态

spupported_speed HBA卡支持的速度

在/sys/class/fc_host/目录下可以得到很过有关HBA卡的信息。

二 如果FC HBA加载了正确的驱动，则在/sys/class/fc_host/hostx下有大量的HBA的
