Linux 挂载iscsi存储磁盘设备

1，check网络

[root@localhost ~]# ping -I eth0 11.110.10.138

PING 11.110.10.138 (11.110.10.138) from 11.110.10.138eth0: 56(84) bytes of data.

[root@localhost ~]#

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

-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

iscsiadm: cannot make connection to 11.110.10.138:Connection refused

^Ciscsiadm: caught SIGINT, exiting...

[root@localhost ifaces]#

ip地址是存储的ip地址

[root@localhost ifaces]# iscsiadm -mdiscovery -t sendtargets -p 11.110.10.22 :3260

[root@localhost ifaces]#

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
