将探测到的存储挂载到本地
root@rhel2 init.d]#iscsiadm -m node -T iqn.2006-01.com.openfiler:tsn.af7b14fe4761 -p 1.1.1.1:3260 -l Logging in to [iface: default, target: iqn.2006-01.com.openfiler:tsn.af7b14fe4761, portal: 1.1.1.1,3260] Login to [iface: default, target: iqn.2006-01.com.openfiler:tsn.af7b14fe4761, portal: 1.1.1.1,3260]: successful
查找当前系统的
[root@vClass-J5j3G iscsi]# iscsiadm -m discovery localhost:3260:3260 via sendtargets 127.0.0.1:3260 via sendtargets
使用 iscsiadm 命令发现服务端并查看服务端的 IQN
#iscsiadm -m discovery -t sendtargets -p 192.168.100.200
使用 iscsiadm 令连接服务端
使用 fdisk -l 查看共享的逻辑磁盘
使用 -u 参数可以登出
搜寻磁盘阵列：iscsiadm –mode discovery –type sendtargets –portal 192.168.1.230
显示磁盘阵列：iscsiadm –mode node
登录磁盘阵列：iscsiadm -m node -T TARGETSNAME -p 192.168.1.230:2360 –l
