首先檢視多路徑裝置：
[root@elt1 block]# multipath -ll

[root@elt1 block]#
那麼如何檢視某個裝置經過哪個hba卡呢？例如檢視mpathf下的sdf和sdm是經過哪個hba卡訪問儲存的呢？
[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]#
再檢視host3和host4的wwpn號：
[root@elt1 block]# cd /sys/class/fc_host/
[root@elt1 fc_host]# ls
host1 host2 host3 host4
[root@elt1 fc_host]#
[root@elt1 fc_host]# cd host3
[root@elt1 host3]# ls

[root@elt1 host3]# cat port_name

[root@elt1 host3]# cat node_name

Mac檢視localhost對應的ip位址
很多時候，我們都輸入過這樣的 http localhost 8080 很熟悉吧！訪問tomcat或者訪問jenkins等web網頁時經常用到，那麼我們經常使用的這個localhost是什麼？字面意思是 本地主機，其代表的就是這台計算機，是給迴路網路介面的標準主機名，對應的ip位址為127.0.0.1...
