iscsiadm常用命令：
# iscsiadm -m discovery -t st -p IP:port //发现iSCSI存储
# iscsiadm -m node -o delete -T TARGET -p IP:port //删除iSCSI发现记录
# iscsiadm -m node //查看iSCSI发现记录
# iscsiadm -m session //查看会话情况
# iscsiadm -m node -T TARGET -p IP:port -l //登录iSCSI存储
# iscsiadm -m node -T TARGET -p IP:port -u //登出iSCSI存储
iSCSI客户端操作：
[root@mysql51 ~]# iscsiadm -m discovery -t st -p 192.168.4.10 //发现iSCSI存储
192.168.4.10:3260,1 iqn.2018-12.com.oven:master
[root@mysql51 ~]# iscsiadm -m node //查看iSCSI发现记录
192.168.4.10:3260,1 iqn.2018-12.com.oven:master
[root@mysql51 ~]# iscsiadm -m session
