在Vistor虚拟带库安装及配置图文详解一文中我们对Vistor有了一个大概了解，本篇将介绍如何在另外一台Linux服务器（介质服务器）上配置Vistor虚拟带库。
架构：
服务器1 hostname：vistor：Vistor本身，iSCSI target，将该服务器看做仅仅是一个带IP的设备。IP 192.168.139.199
服务器2 hostname：cent41：介质服务器，iSCSI initiator，IP 192.168.139.133，操作系统CentOS4.4
服务器1上的操作：
通过web方式进行虚拟带库的配置，参照Vistor虚拟带库安装及配置图文详解,
确保状态是running。
服务器2上的操作：
1、编辑/etc/iscsi.conf文件，加入语句：DiscoveryAddress=192.168.139.199:3260 ---这里用的ip是服务器1的。
2、重启iscsi服务：service iscsi restart
3、编辑/etc/initiatorname.iscsi 修改initiator的名字为你自定义的，这里我们用cent41
4、重启iscsi，/etc/init.d/iscsi restart

5、[root@cent41 ~]# tail /var/log/messages
