在Oracle Linux 6.1 上安装11.2.0.1 的RAC，在安装grid时执行root.sh 脚本，报错，如下：
[root@rac1 bin]#/u01/app/11.2.0/grid/root.sh

The following environment variables are setas:

据说这个错误只在linux 6.1下，且Oracle 版本为11.2.0.1的时候出现，在11.2.0.3的时候就不会有这种问题，而解决方法就是在生成了文件/var/tmp/.oracle/npohasd文件后，root立即执行命令：
/bin/dd if=/var/tmp/.oracle/npohasd of=/dev/nullbs=1024 count=1
这里有两种方法：1.清除grid，2，清除root.sh.
在我们继续执行之前先清除GRID，具体步骤参考：
http://blog.csdn.net/tianlesoftware/article/details/5892225
在所有节点执行：
rm –rf /etc/oracle/*
rm -rf /etc/init.d/init.cssd
rm -rf /etc/init.d/init.crs
rm -rf /etc/init.d/init.crsd
rm -rf /etc/init.d/init.evmd
rm -rf /etc/rc2.d/K96init.crs
rm -rf /etc/rc2.d/S96init.crs
rm -rf /etc/rc3.d/K96init.crs
rm -rf /etc/rc3.d/S96init.crs
rm -rf /etc/rc5.d/K96init.crs
rm -rf /etc/rc5.d/S96init.crs
rm -rf /etc/oracle/scls_scr
rm -rf /etc/inittab.crs
rm -rf /var/tmp/.oracle/*
or
rm -rf /tmp/.oracle/*
移除ocr.loc 文件，通常在/etc/oracle 目录下：
[root@rac1 ~]# cd /etc/oracle
You have new mail in /var/spool/mail/root
[root@rac1 oracle]# ls
lastgasp ocr.loc ocr.loc.orig olr.loc olr.loc.orig oprocd
[root@rac1 oracle]# rm -rf ocr.*
格式化ASM 裸设备：
[root@rac1 utl]# ll /dev/asm*
brw-rw---- 1 oracle dba 8, 17 Jun 27 09:38 /dev/asm-disk1
brw-rw---- 1 oracle dba 8, 33 Jun 27 09:38/dev/asm-disk2
brw-rw---- 1 oracle dba 8, 49 Jun 27 09:38/dev/asm-disk3
brw-rw---- 1 oracle dba 8, 65 Jun 27 09:38/dev/asm-disk4
dd if=/dev/zero of=/dev/asm-disk1 bs=1Mcount=256
dd if=/dev/zero of=/dev/asm-disk2 bs=1Mcount=256
dd if=/dev/zero of=/dev/asm-disk3 bs=1Mcount=256
dd if=/dev/zero of=/dev/asm-disk4 bs=1Mcount=256
移除/tmp/CVU* 目录：
[root@rac1 ~]# rm -rf /tmp/CVU*
删除/var/opt目录下的Oracle信息和ORACLE_BASE目录:
# rm -rf /data/oracle
# rm -rf /var/opt/oracle
删除/usr/local/bin目录下的设置：
# rm -rf /usr/local/bin/dbhome
# rm -rf /usr/local/bin/oraenv
# rm -rf /usr/local/bin/coraenv
移除Grid 安装目录，并重建：
[root@rac1 oracle]# rm -rf /u01/app
[root@rac2 u01]# mkdir -p /u01/app/11.2.0/grid
[root@rac2 u01]# mkdir -p/u01/app/oracle/product/11.2.0/db_1
[root@rac2 u01]# chown -R oracle:oinstall/u01
[root@rac2 u01]# chmod -R775 /u01/
使用rootcrs.pl 命令来清楚记录，命令如下：
[root@rac1 oracle]#/u01/app/11.2.0/grid/crs/install/rootcrs.pl-deconfig -verbose -force

--------注意-------------
看到root.sh 执行到这里的时候，我们就可以在另一个窗口不断的刷我们的dd命令了，如果有更好的方法也可以，我这里是这么操作的：
[root@rac1 ~]# /bin/ddif=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1
/bin/dd: opening`/var/tmp/.oracle/npohasd': No such file or directory

You have new mail in /var/spool/mail/root
[root@rac1 ~]# /bin/ddif=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1
--只要dd命令成功执行，我们的root.sh 就可以顺利完成了。
