安装了很多次oracle RAC for linux，ASM，系统日志老是报大量类似的错误：

日立、IBM和EMC存储都是这种情况，下边是EMC存储的fdisk -l信息:

这个我在rhel 5.6单光纤连接DS5300时碰到过，启动的时候，一堆这样的类似错误，非常慢，后来安装了RDAC之后，会自动创建一个mpp启动镜像，启动就一切正常了。

楼上说的跟我的情况不一样啊

没人遇到过吗？我装了很多次asm 的RAC都是这样啊

作者: comerliang 时间: 2012-08-27 08:53

有人解决过这样的问题吗？

你可以看下启动哪个服务后报的这些错误（应该是multipathd），这时候iscsi服务还没有启动，这个是没有问题的。
同时在/etc/init.d下面确认各个服务的启动级别。

楼上的能说明白点吗？
