在Linux下查看FC HBA卡的速率和状态

查看FC HBA卡的WWN号

一般是在/sys/class/fc_host/host*/目录下

 
[root@localhost ~]#cat  /sys/class/fc_host/host2/port_name
0x2100001b329240d7
[root@localhost ~]#cat  /sys/class/fc_host/host2/node_name
0x2100001b329240d7
[root@localhost ~]#cat  /sys/class/fc_host/host2/fabric_name
0x2100001b329240d7

查看当前port的状态

 
[root@localhost ~]#cat  /sys/class/fc_host/host2/port_state
Online

查看PORT的端口ID

 
[root@localhost ~]#cat  /sys/class/fc_host/host2/port_id
0x000001

查看port支持的速率

 
[root@localhost ~]#cat  /sys/class/fc_host/host2/supported_speeds
1 Gbit, 2 Gbit, 4 Gbit 
[root@localhost ~]#cat  /sys/class/fc_host/host2/supported_classes
Class 3

在FC HBA没有插上光纤时

 
[root@localhost ~]#cat  /sys/class/fc_host/host2/speed
unknow
[root@localhost ~]#cat  /sys/class/fc_host/host2/port_type
unknow

给FC HBA卡插上光纤线,和其他HBA卡相连时。

 
[root@localhost ~]#cat  /sys/class/fc_host/host2/speed
4 Gbit 
[root@localhost ~]#cat  /sys/class/fc_host/host2/port_type
LPort (private loop) 

和光纤交换机相连时

 
[root@localhost ~]#cat  /sys/class/fc_host/host2/port_type
