最近一个土豪客户要更换存储（原存储IBM DS8300，新存储EMC VMAX 20K，这都是高端存储），因此涉及到系统和数据库的迁移，这个项目很大，据说三年前就已经开始策划。其中要迁移的核心数据库是一套DB2，数据量达30T+，还有一套11.2.0.2 Oracle RAC，数据量500G+，DB2迁移暂先不说，因为不是专门搞那个的。由于要负责这套Oracle RAC的迁移，采用的迁移方案是，先将OCR&VOTE ASM磁盘组在线从原存储IBM DS8300迁移到新存储EMC VMAX 20K的ASM磁盘组上，然后将集群全部关闭，通过存储间的拷贝方式将原IBM DS8300存储上的DATA和ARCH ASM磁盘组中的数据拷贝到新存储EMC VMAX 20K上，拷贝完成后，扫描磁盘然后启动集群。这里我们不讨论这个迁移方案是否合理，因为这其中夹杂着很多政治因素，我们只关心迁移方案中的第一步，即OCR&VOTE ASM磁盘组在线迁移问题。其实，这里我们并不用非常关心OCR&VOTE ASM磁盘组到底是从IBM DS8300迁移到EMC VMAX 20K上还是从EMC VMAX 20K迁移到IBM DS8300上，因为从本质上讲只是将OCR&VOTE换一个位置而已。下面是我在自己虚拟机上进行的一个测试，特记录一下，留作备用。

----这里不执行19步无法删除该磁盘组
20.整个迁移过程结束
以上为Oracle 11gR2在线迁移OCR&VOTE ASM磁盘组过程，其中不涉及存储中所使用多路径软件问题，如果涉及到存储磁盘路径改变，则需要去修改ASM实例的disk_strings参数，具体操作可以参考Maclea的这篇博客在11gR2 RAC中修改ASM DISK Path磁盘路径，论坛贴链接[讨论]11G RAC更换存储，如有问题，欢迎讨论。
写的很好！感谢！
