3.错误代码：D5385D18

解决方法：实际上,盘阵上也没有报硬盘的错误,交换机也正常,经过检查,最后修改了chdev -l hdisk6 -a rw_timeout=1000(这个值有点偏大)解决了此问题

环境是AIX5200-04,DS4300盘阵,F08光纤交换机

故障现象:

   升级AIX的5200-06的补丁之后,系统开始频繁地报

这样的错误,实际上,盘阵上也没有报硬盘的错误,交换机也正常,经过检查,最后修改了chdev -l hdisk6 -a rw_timeout=1000(这个值有点偏大)解决了此问题.经过求证,在网上找到一个类似的说明:

Early vendor support recommendation is to increase rw_timeout, as they judge it as characteristic of a long fibre connection, but cables are only 15 metre, and due to its nature, we are loathe to start performing outages just to tweak settings that shouldn't be causing issue.
