1.2. 在FAS 3160上创建配置
1.2.1. 配置aggr，vol，lun
参照fas3140的配置分别在3160a和3160b上创建aggr、vol、lun，fas3160上的vol和lun的空间需要≥3140上面的配置。
fas3160a：

Fas3160b：

1.2.2. 编辑配置文件
编辑/etc/hosts 、/etc/exports/etc/rc

1.2.3. 配置临时网络地址

1.3. 进行snapmirror数据迁移
1.3.1. 检查FAS3160 dataontap系统版本
检查Sysconfig –a的输出，确定FAS3160的data on tap版本要不低于FAS3140。如果系统版本低于FAS3140，需要先升级微码，否则无法进行snapmirror。

1.3.2. 定义snapmirror配置文件
编辑/etc/snapmirror.conf

1.3.3. 执行snapmirror复制命令开始数据复制
依次对所有vol执行snapmirror命令
建立vol0间的snapmirror关系，开始数据复制：
snapmirror initialize -S systemA:vol0 systemB:vol0

查看snapmirror状态，确认状态为transferring，表面数据传输开始进行。
Snapmirror status

1.3.4. 验证数据
通过查看snapmirror状态，确认所有vol状态为Snapmirrored。
Snapmirror status

进行FAS3140到FAS3160的应用切换，修改Fas3160上面的网络配置，进行数据验证。

2. Netapp2240-2和Netapp 2240-4增加卷配置Snapmirror
本次要新增snapmirror的卷是DSEP平台使用的2个3.5T的卷，由netapp2240-2使用FC的形式分配给DSEP 的两台IO节点

2.1. 检查确认Netapp 2240-2和Netapp 2240-4的配置情况
