INS-20802 Oracle Cluster Verification 实用程序失败

[b]INS-20802 Oracle Cluster Verification 实用程序失败[/b]

问题现象：






Grid安装到最后一步，两边的root脚本也执行完了，撂出个INS-20802错误，从错误现象来看，看不出什么问题，提示查看.log文件。

Log文件内容：
INFO: Checking Single ClientAccess Name (SCAN)...

INFO: Checking name resolution setup for "SCAN"...

INFO: ERROR:

INFO: PRVF-4664 : Found inconsistent name resolution entries for SCAN name"SCAN"

INFO: ERROR:

INFO: PRVF-4657 : Name resolution setup check for "SCAN" (IP address:172.16.9.150) failed

INFO: ERROR:

INFO: PRVF-4664 : Found inconsistent name resolution entries for SCAN name"SCAN"

INFO: Verification of SCAN VIP and Listener setup failed


问题分析：
通过参考Metalink[ID887471]文章得出以下结论：

由于配置了/etc/hosts来解析SCAN，导致未走DNS来进行SCAN的解析，爆出此错误，可以考虑忽略掉，或者删除/etc/hosts文件中的SCAN解析部分，并且再次通过nslookup验证DNS的解析是否正常即可。
