现象
11.2.0.4单实例ASM安装报错“ ohasd failed to start at /u01/app/11.2.0/grid/crs/install/roothas.pl line 377, line 73.”
-- 报错：
ohasd failed to start at /u01/app/11.2.0/grid/crs/install/roothas.pl line 377, <ALERTLOG> line 73.
-- 解决：
$GRID_HOME/crs/install/roothas.pl -deconfig -force -verbose
/u01/app/11.2.0/grid/perl/bin/perl -I/u01/app/11.2.0/grid/perl/lib -I/u01/app/11.2.0/grid/crs/install /u01/app/11.2.0/grid/crs/install/roothas.pl
-- 在执行root.sh脚本时出现“Adding Clusterware entries to inittab”的时候，在另一个窗口使用root立即执行以下命令：
dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1（等待root.sh成功执行完毕后可以ctrl+c取消这里的命令）
环境
系统环境：Linux Server release 7.3
**数据库环境：11.2.0.4.0
**
执行脚本 /u01/app/11.2.0/grid/root.sh，报错如下：
[root@Oraclelinux ~]# /u01/app/11.2.0/grid/root.sh

解决方案:
第一步，回退root.sh脚本操作
[root@Oraclelinux ~]# /u01/app/11.2.0/grid/crs/install/roothas.pl -deconfig -force -verbose
Using configuration parameter file: /u01/app/11.2.0/grid/crs/install/crsconfig_params

CRS-4544: Unable to connect to OHAS

第二步：
dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1
（等待root.sh成功执行完毕后可以ctrl+c取消这里的命令）
OK，此时Grid 安装通过。
