OUI-25031:Some of the configuration assistants failed/cancelled.解决办
环境：
oracle 11g R1
CentOS 5.4
安装clusterware时报错，
查看日志:
Configuration assistant "Oracle Cluster Verification Utility" failed
-----------------------------------------------------------------------------
The "/oracle/product/crs/cfgtoollogs/configToolFailedCommands" script contains all commands that failed, were skipped or were cancelled. This file may be used to run these configuration assistants outside of OUI. Note that you may have to update this script with passwords (if any) before executing the same.-----------------------------------------------------------------------------Output generated from configuration assistant "Oracle Cluster Verification Utility" (attempt 6):
Command = /oracle/product/crs/bin/cluvfy stage -post crsinst -n rac1,rac2
ERROR:
Cannot identify the operating system. Ensure that correct software is being executed for this operating system.
Verification cannot proceed.
在网上查找答案都说是/etc/hosts 、/etc/sysconfig/network里面的主机名解析不对，我检查了主机名没问题。从上面的错误提示得知问题出在操作系统验证无法通过上。
<SPAN style=""color: #ff0000'">解决办法：
vi $CRS_HOME/cv/admin/cvu_config
将#CV_ASSUME_DISTID=RHEL4 修改为：CV_ASSUME_DISTID=RHEL5
保存退出后，重新检测，OK！
