首先查看多路径设备：

[root@elt1 block]# multipath -ll

[root@elt1 block]# 

那么如何查看某个设备经过哪个HBA卡呢？例如查看mpathf下的sdf和sdm是经过哪个HBA卡访问存储的呢？

[root@elt1 block]# cd /sys/block
[root@elt1 block]# ls -l

[root@elt1 block]# ls -l|grep -E "sdh|sdo"
lrwxrwxrwx 1 root root 0 Jun  1 10:09 sdh -> ../devices/pci0000:40/0000:40:02.0/0000:41:00.0/host3/rport-3:0-0/target3:0:0/3:0:0:6/block/sdh
lrwxrwxrwx 1 root root 0 Jun  2 21:19 sdo -> ../devices/pci0000:40/0000:40:03.0/0000:51:00.0/host4/rport-4:0-0/target4:0:0/4:0:0:6/block/sdo
[root@elt1 block]# 

再查看host3和host4的WWPN号：

[root@elt1 block]# cd /sys/class/fc_host/
[root@elt1 fc_host]# ls
host1  host2  host3  host4
[root@elt1 fc_host]# 

进入host3并查看相关信息：

[root@elt1 fc_host]# cd host3
[root@elt1 host3]# ls
device        issue_lip        npiv_vports_inuse  port_state  speed       supported_classes  system_hostname  vport_create
dev_loss_tmo  max_npiv_vports  port_id            port_type   statistics  supported_speeds   tgtid_bind_type  vport_delete
fabric_name   node_name        port_name          power       subsystem   symbolic_name      uevent


[root@elt1 host3]# cat port_name
0x21000024ff0f597b
[root@elt1 host3]# cat node_name
0x20000024ff0f597b
[root@elt1 host3]#
