aix6.1(6106)上安装oracle 11g r2 grid单机执行root.sh报错Failed to start the Clusterware的处理方法

报错日志如下：

#/oracle/app/11.2.0/grid/root.sh

Adding daemon to inittab

同时检查并无相关可参考的日志，在网上和官方查询，基本可以定为是oracle bug，最终解决方法为：
$GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force
oracle/app/11.2.0/grid/root.sh
在Adding daemon to inittab的时候，立即打开另一个窗口执行：
dd of=/dev/null if=/tmp/.oracle/npohasd bs=1024 count=1
即可。

但是发现重启操作系统仍然无法启动，只能手工运行。
crsctl start has
同时开窗口执行
dd of=/dev/null if=/tmp/.oracle/npohasd bs=1024 count=1
即可。

如果不能自动启动，解决方法如下：

vi /etc/init/oracle-ohasd.conf
增加：
# Oracle OHASD startup
start on runlevel [35]
stop on runlevel [!35]
respawn
exec /etc/init.d/init.ohasd run >/dev/null 2>&1
