实验设备:
用虚拟机虚拟两个 redhat linux 6.3 -64bit 系统,并配置好yum
ip设置:
scsi服务端:10.1.1.222
scsi客户端(挂载端):10.1.1.1
实验开始:
1、在服务端安装软件并配置好共享的磁盘,首先在虚拟机中新加入一块硬盘,大小随意。(这里添加100G)

2、安装scsi服务端软件
1
| yum install scsi-target-utils -y
|
共享磁盘(在配置文件中加入以下代码即可)

2
3
4
| vim /etc/tgt/targets.conf
<target iqn.2008-09.com.example:server.target1>
backing-store /dev/sdb
</target>
|
启动服务
关闭防火墙和selinux
3、在客户端安装客户端软件,并设置挂载
安装客户端软件
1
| yum install iscsi-initiator-utils -y
|
查看是否有共享磁盘
1
2
| iscsiadm --mode discoverydb --type sendtargets --portal 10.1.1.222 --discover
出现以下则表示有共享磁盘 10.1.1.222:3260,1 iqn.2008-09.com.example:server.target1
|
挂载磁盘
1
| iscsiadm --mode node --targetname iqn.2008-09.com.example:server.target1 --portal 10.1.1.222:3260 --login
|
注意:中间2008-09这段是填写上面查询出来的那个磁盘名
成功挂载后有以下提示
