1，check网络
[root@localhost ~]# ping -I eth0 11.110.10.138

2,检測软件是否已经安装
[root@localhost ~]# rpm -qa |grep iscsi
iscsi-initiator-utils-6.2.0.873-2.0.2.el6.x86_64
[root@localhost ~]#

3,检查ISCSI服务是否启动了和当前级别下的执行情况
[root@localhost ~]# service iscsi status
......
4。要建立2个文件
[root@localhost ~]# iscsiadm -m iface -Iiscsi_eth0 --op=new
New interface iscsi_eth0 added
[root@localhost ~]# iscsiadm -m iface -Iiscsi_eth1 --op=new
New interface iscsi_eth1 added
[root@localhost ~]#
5.建立iscsi_eth0和eht0的映射关系。
同一时候建立iscsi_eth1和eth1的映射关系.
也能够直接编辑iscsi_eth0和iscsi_eth1文件，把里面的iface.net_ifacename=default改成
iface.net_ifacename=eth0和iface.net_ifacename=eth1就可以。
[root@localhost ~]# ls/var/lib/iscsi/ifaces/
iscsi_eth0 iscsi_eth1 iscsi_the0 iscsi_the1
[root@localhost ~]# cd/var/lib/iscsi/ifaces/
[root@localhost ifaces]# ll
总用量 16
-rw------- 1 root root 197 6月 10 16:05 iscsi_eth0
-rw------- 1 root root 197 6月 10 16:06 iscsi_eth1
-rw------- 1 root root 197 4月 3 19:14 iscsi_the0
-rw------- 1 root root 197 4月 3 19:14 iscsi_the1
[root@localhost ifaces]# cat iscsi_eth0
# BEGIN RECORD 6.2.0-873.2.el6
iface.iscsi_ifacename = iscsi_eth0
iface.transport_name = tcp
iface.vlan_id = 0
iface.vlan_priority = 0
iface.iface_num = 0
iface.mtu = 0
iface.port = 0
# END RECORD
[root@localhost ifaces]#
[root@localhost ifaces]# iscsiadm -m iface-I iscsi_eth0 --op=update -n iface.net_ifacename -v eth0
iscsi_eth0 updated.
[root@localhost ifaces]# iscsiadm -m iface-I iscsi_eth0 --op=update -n iface.net_ifacename -v eth0
iscsi_eth0 updated.
[root@localhost ifaces]#
6,重新启动iscsi服务
[root@localhost ifaces]# service iscsi restart
停止 iscsi： [确定]
正在启动 iscsi： [确定]
[root@localhost ifaces]#
Equallogic配置部分
7.配置Equallogic，映射一个Lun名字为redhat,大小3G的空间
在存储訪问站点上，去分配新的磁盘块，这个比較简单。就不截图了，存储设备都会自带一个网址让我们訪问的。
Redhat配置部分
8.做discover。能够发现已经看到了redhat的lun。由于有两条路径。全部显示了两行。
[root@localhost ifaces]# iscsiadm -mdiscovery -t sendtargets -p 11.110.10.138:3260

9.Log on全部的iscsi session，能够看到最后两个successful的redhat lun，已经log on成功了。
[root@localhost ifaces]# iscsiadm -m node-l
