至此两个节点的该磁盘组就陷入了不停的mount，然后dismount的轮流循环中.这里我们可以大概的分析出来,由于vg的磁盘组被写入了数据或者强制剔除的时候导致asm写入该文件的数据被破坏,导致后续的asm reblance遭遇坏块,然后直接dismount.对于该问题的解决方案,通过对对该磁盘组的acd和cod进行patch,让其不进行reblance,保持该磁盘组现在,稳定的mount状态,然后对其数据进行备份和重建该磁盘组.这个客户运气不错,vg中的asm disk磁盘写入较少,数据库运行正常.
对于这种情况,如果发生极端损坏,比如asm磁盘组无法mount,可以参考:找回ASM中数据文件
如果是asm的元数据大量损坏,无法通过asm字典级别恢复,可以通过参考:asm disk header 彻底损坏恢复

由于某种原因导致该dmp异常了,而且客户的主要数据都在这个表里面,因此找我们进行恢复处理.通过工具扫描,确定dmp基本上是好的.进行二次处理,把该dmp中这个表重新恢复成dmp文件,然后导入数据库，完成恢复(包括解决某些工具有汉字乱码问题,和sqlldr换行导入问题等)
