环境：
平台:RedHat EnterPrise 5.8 X86_X64
数据库:Oracle EnterPrise 11.2.0.3
集群软件:Oracle grid 11.2.0.3
故障现象：
数据库出现了归档失败，其中有一个节点的实例出现HANG死的状况。
日志信息如下:

分析:
由于归档失败发生在ASM磁盘上，首先检查ASM磁盘空间以及DB_RECOVERY_FILE_DEST_SIZE，ASM磁盘空间是足够的，而且由于只有一个节点出现出现了无法归档的问题，也可以排除是空间不足造成的。确认两个节点的DB_RECOVERY_FILE_DEST_SIZE参数设置都是0，基本上可以判断问题和当前节点的ASM实例状态不正常有关。
检查ASM实例的错误信息：

当前节点ASM实例出现了的这个信息，说明报错发生在实例2上：
