求解析ERRPT报错日志

[blingpro]

问题如下:
oracle安装在AIX上，oracle一直在等待IO返回，导致数据库无响应，errpt大量报错如下（每几分钟就产生，后来只能重启主机，这个报错才消失），哪位大神指点下，谢谢！另有没有errpt详细的分析方法或手册，包括具体一些报错类型讲解的文档？
我自己初步怀疑：某disk有问题或者通道有问题，导致一直打开disk的数据异常。

因为不知你有没有把日志贴全，所以不知有多少这样的报错。这样的报错可能是链路和盘的问题。看来兄弟用的是IBM存储。我的经验是如果一个盘的多个路径总是同时出问题，而且总是某个盘出问题，那么盘出问题的机率大。相反如果不固定，就可能是链路出问题了。我之前是在EMC的 cx4-960上处理过类似问题。
