主机操作系统：RHEL6.5_64
共享存储使用VMWARE创建共享磁盘文件
数据库版本：Oracle11gR2 11.2.0.4.0_RAC
Oracle数据库文件部署在ASM磁盘组上，需要在不停机或者尽量短的停机时间完成存储迁移。由于只是设计存储更换，无需借助第三方工具。采取迁移ASM DISKGROUP的方式完成迁移。模拟现实环境中，ASM磁盘组存放在存储设备上，模拟由于设备升级、存储虚拟化整合或者存储设备淘汰，需要进行存储更换。
首先使用新建ASM GROUP,使用rman copy替换旧有的存储ASM group，然后再采取ASM Rebalance进行在线迁移回来。两种方法
数据为重，首先应该有完整可恢复的数据备份，确保数据的安全性。再进行迁移。迁移前首先收集数据库现有的信息。
1) 划分asm disk，并检查或更改UDEV配置文件，使得新存储的asm disk对ASM实例可识别。 2) 备份OCR、Voting Disk、ASM disk header和数据库。 3) 创建新的DISKGROUP 4) 迁移OCR和Vote Disks到新磁盘组（ASM diskgroup） 5) 迁移ASM Spfile到新磁盘组（ASM diskgroup） 6) 迁移数据库相关文件至新磁盘组（ASM diskgroup） 7) 在线修改数据库参数文件（归档路径、闪回等） 8) 删除旧磁盘组 9) 观察期。 10) 执行数据库备份
模拟环境中，是用VMware创建共享磁盘文件实现新存储划分。新创建3个10G新共享存储磁盘，ndata1，ndata2，ndata3用于存放数据文件，新建3个1GB共享存储磁盘，nocr1，nocr2，nocr3，用于存放OCR与VOTE信息，将原存储上的数据全部迁移过来。

选择独立模式，保留现有格式，磁盘设置，高级设置中，修改虚拟设备节点，与本地磁盘不在同一总线上。在两节点都添加6块新盘。
主机端识别新划盘：分别是sdh、sdi、sdj，三块10GB的磁盘，sdk，sdl，sdm，为3块1GB的磁盘。
