CRS-4124: Oracle High Availability Services startup failed.

CRS-4000: Command Start failed, or completed with errors.

ohasd failed to start: Inappropriate ioctl for device

ohasd failed to start at/u01/app/11.2.0/grid/crs/install/rootcrs.pl line 443.

第一次安装11gR2 RAC的时候就遇到了这个11.0.2.1的经典问题,上网一查才知道这是个bug,解决办法也很简单,

就是在执行root.sh之前执行以下命令

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

如果出现

/bin/dd: opening`/var/tmp/.oracle/npohasd': No such file or directory

的时候文件还没生成就继续执行,直到能执行为止,一般出现Adding daemon to inittab这条信息的时候执行dd命令。

另外还有一种解决方法就是更改文件权限

chown root:oinstall /var/tmp/.oracle/npohasd

重新执行root.sh之前别忘了删除配置:/u01/app/11.2.0/grid/crs/install/roothas.pl -deconfig -force-verbose
