节点2 asm dismount导致redo写报错(ORA-00340,ORA-00345)，经过分析asm和系统日志,确认是由于多路径异常导致io异常

由于节点2是突然crash，节点1做实例恢复失败，由于节点2的redo发生了写丢失,导致节点1实例恢复后库crash,进而是的该集群的相关数据库节点全部crash

*****************************************************************
An internal routine has requested a dump of selected redo.
This usually happens following a specific internal error, when
analysis of the redo logs will help Oracle Support with the
diagnosis.
It is recommended that you retain all the redo logs generated (by
all the instances) during the past 12 hours, in case additional
redo dumps are required to help with the diagnosis.

该错误是12c之后才有的报错,由于文件异常导致,通过以前的解决经验,接手这个问题之后快速调整数据库文件头信息,顺利open库
