两节点RAC系统突然报卷被锁，导致数据异常关闭

当出现如下错误时，所有节点系统正常，HACMP也正常，而且HACMP也没出现新日志。只是db出现异常关闭，原因是有一些设备无法读写。

卷组是并发模式的。故障发生时存储也没有任务报错。
os:5300-06-06
HACMP:5.3-sp12
采用磁盘心跳
此系统已经平稳运行1年多了，之前也没出现过这种情况。这周突然发生了2次上述情况。当是系统也没有root用户在系统上执行一些类似cfgmgr的操作。而且HACMP也没出现异常，当时也没日志。只是oracle异常停止，之后重新启动oracle,而且要做recover.

看看数据库日志。

对，看数据库日志，数据库异常关闭，应该会有日志
