RAC安装在节点2执行root.sh报错处理
今天在网上帮人处理RAC安装故障
环境是centos5.8，RAC11.2.0
节点1很好，节点2执行root.sh后报错

ASM配置有问题，先让他查看权限是否正确
ll /dev/mapper/
这里没有问题，是oracle 和 oinstall
检查grid用户也在oinstall组里
后面检查发现有报错
DiskGroup OCR creation failed with the following message:
ORA-15018: diskgroup cannot be created
ORA-15072: command requires at least 1 regular failure groups, discovered only 0
于是确认了问题，之前在david的博客里看到过
具体的可以去

我这里仅记录下处理步骤，先尝试在节点2上操作，不行就在所有节点均做操作
1、修改/etc/sysconfig/oracleasm文件，将文件中ORACLEASM_SCANORDER和ORACLEASM_SCANEXCLUDE参数改为ORACLEASM_SCANORDER="dm"，ORACLEASM_SCANEXCLUDE="sd"
2、重启ASMLIB #/etc/init.d/oracleasm restart
3、清除之前的注册信息 #/oracle/grid/crs/install/roothas.pl -delete -force -verbose
4、重新在节点2执行root.sh文件 ----这里可真就是节点2了
