oracle 11gR2 rac 安装完grid到最后一步Oracle Cluster Verification Utility post check时报错,这是提示查看installActions2010-03-01_03-16-59PM.log时,日志中记录以下错误
INFO: Checking name resolution setup for "abc-cluster-scan"...
INFO: ERROR:
INFO: PRVF-4664 : Found inconsistent name resolution entries for SCAN name "abc-cluster-scan"
INFO: ERROR:
INFO: PRVF-4657 : Name resolution setup check for "abc-cluster-scan" (IP address: 192.168.3.227) failed
INFO: Post-check for cluster services setup was unsuccessful on all the nodes.
scan name和ip是写在/etc/hosts中的,而没有采用DNS或GNS

通过查询metalink,文档ID为887471.1
CauseCause 1. SCAN name is resolved by hosts file instead of DNS or http://download.oracle.com/docs/cd/E11882_01/install.112/e10812/prelinux.htm#BABHCDII]GNS, this could happen even you list all SCAN IP(s) in hosts file
Solution List
For cause 1: Oracle strongly recommend to use DNS or GNS for SCAN name resolution as hosts file support only one IP for SCAN name.

If you intended to use hosts file for SCAN name resolution, and ping command returns correct SCAN VIP, you can ignore the error and move forward.
采用/etc/hosts方式的话,只能一个scan name和ip, ping scan name能返回正确ip的
话,那这个报错可以忽略。
