找尋 iSCSI-target 與重起 iSCSI-initiator
iscsiadm -m discovery -t sendtargets -p 192.168.11.250
service iscsi restart

如果出現無法登入的狀況，可能要調整權限設定的部份
可以透過 iscsiadm 工具執行檢視問題點 Exp.
iscsiadm -m node -p 192.168.11.250 -T iqn.2009-10.com.ichiayi:storage.data1t.iscsi.data01 -l -d 10
* 如果有正常連上就會有以上的訊息 login to [xxx] : successful
