进入linux后使用ifconfig -a查看ip地址
#ifconfig -a

#iscsiadm -h
向192.168.188.129这个服务器发送请求识别 会提示找不到客户端
#iscsiadm -m discovery -t sendtargets -p 192.168.188.129
iscsiadm: No portals found
配置域控制器
连接控制器服务器
在管理控制台配置san客户端
选择服务器ip
下一步然后勾选linux操作系统本机的ip192.168.188.11
选绿色的，绿色的代表为分配任何客户端
然后会看到客户端名称
在管理控制台为客户端分配20GB磁盘
一直下一步
进入linux、客户端
最后再重试这个命令，就可以
#iscsiadm -m discovery -t sendtargets -p 192.168.188.129
