RHEL6.3上的Oracle11gR2 版本为：11.2.0.1 在重启服务器后不能启动CSS服务，在以前服务器重启后没有出现这个情况，检查css服务器状态，报错：

但是我发现在RHEL6.3上启动has服务并不能只使用crsctl start has 这个命令来启动，还必须以root用户去执行

/etc/init.d/init.ohasd run 这命令，才能启动has服务，不然crsctl start has 会一直挂着且也不能启动。

这个问题其实在装软件的时候就碰到了，在RHEL6.3上装11gR2 在执行root.sh脚本的时候会报错：

Adding daemon to inittab

CRS-4124: Oracle High Availability Servicesstartup failed.

CRS-4000: Command Start failed, orcompleted with errors.

ohasd failed to start: 对设备不适当的 ioctl操作

ohasdfailed to start: 对设备不适当的 ioctl 操作 at /grid/base/grid/crs/install/roothas.pl line296.

在RHEL6.3上解决这个错误的方法是：

官网的解决办法（亲测~没有用，但还是写出来）

1、/usr/local/bin目录下没有perl这个文件

解决办法：

ln -s/usr/bin/perl /usr/local/bin/perl

 

2、存在 /tmp/.oracle or /var/tmp/.oracle or/usr/tmp/.oracle.这几个文件

解决办法：

rm -rf /tmp/.oracle/*/usr/tmp/.oracle/* /var/tmp/.oracle/*

非官网的解决办法（解决办法来自于博客“语虎店”的文章 ，连接：http://yuhushop.com/?p=453）

在执行root.sh的时候，会生成/var/tmp/.oracle/npohasd文件，解决的办法就是在执行root.sh的时候，当生成了 /var/tmp/.oracle/npohasd 后，立即执行 ：

dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1

 然后再执行root.sh命令。重新执行root.sh命令之前要先执行一个deconfig操作

在GRID_HOME/crs/install目录下

./roothas.pl-deconfig -force -verbose
