配置光纤交换机
1.安装jre_1.6.x版本java，将配置本机IP为10.77.77.0网段，通过浏览器登录交换机图形界面或命令行telnet、ssh登录，
username：admin Password：password
2.登录后到如下图界面，点击switch admin
3.这时显示wwn和license信息
4.点击new alias创建新的别名
5.在Member Selection list中选择要取别名的端口添加到右边alias Member中（这里给端口设置别名的
作用主要是为了方便后期管理，也可以不设置别名）
6.点击new zone创建新的zone，并将前面相应的设置别名的端口添加到zone member中
7.创建new zone config，并将需要启用的zone添加到config member中，然后save config，
最后enable config完成配置
这里新建了4个zone，加入到了一个zone config，save config和enable config后完成配置。
一． VNX5200安装和配置
1. 安装jre_1.6以上版本，本地windows网络连接VNX5200的A控SPA，通过浏览器访问
https://1.1.1.1, username: sysadmin
Password： sysadmin
2.选择要配置的存储systems，导航到Storage –>Storage poolsàRaid Groups
创建新的storge pools或raid groups，建议创建storge pools方便后期扩展
a．第一种方法创建raid groups
点击create创建新的Raid Groups：选择RAID types和manual，select相应的磁盘(注意前面4块盘disk0~disk4为存储系统盘，不要动)
create lun
创建第2个lun和第3个lun
b．第2种方法创建storage pools
b1.这里选择EMC建议的4+1块盘创建storage pools
b2. 接下来创建3个600g的lun
3.创建热备盘hot space，这里不需要单独创建hot space，因为vnx5200的默认热备盘策略是将所有未配置的非系统盘设置成hot space，所以这里只需保留一块未设置的disk即可。
4.连接好光纤交换机,存储和服务器之间的线路，配置好光纤交换机，点击initiators刷新，
并注册initiators,这里hostname和ip address是自定义的。
5.创建storage groups，并连接connects luns和connects hosts
成功完成connects luns和connects hosts后状态如下：
6.登录到linux主机，安装powerpath软件，查看是否映射成功
