环境信息：
EBS----------------11.5.10.2
RDBMS-----------11.2.0.3.8
APP OS-----------Linux 4.5（32bit）
DB OS-------------AIX6.1
Symptoms
这几天开始给ebs单实例转换为RAC。在安装grid软件时，出现如下错误：
INS-20802 Oracl Cluster Verlfication Utility failed
Cause
进一步查看日志，日志记录如下：
INFO: ERROR:
INFO: PRVG-1101 : SCAN name"test-cluster-scan" failed to resolve
INFO: ERROR:
INFO: PRVF-4657 : Name resolution setupcheck for "test-cluster-scan" (IP address: 10.16.1.110) failed
INFO: ERROR:
INFO: PRVF-4663 : Found configurationissue with the 'hosts' entry in the /etc/nsswitch.conf file
INFO: Verification of SCAN VIP andListener setup failed
Solution
参考note:PRVF-4664PRVF-4657: Found inconsistent name resolution entries for SCAN name (Doc ID887471.1)
If the intention is to use hosts file for SCAN name resolution, and ping command returns correct SCAN VIP, you can ignore the error and move forward.
If the intention is to use DNS or GNS for SCAN name resolution, comment out entries in local hosts file for SCAN name on all nodes, and re-run "$GRID_HOME/bin/cluvfy comp scan" to confirm.
因为以后不会使用到SCAN IP，/etc/hosts中SCAN IP只是为了安装
所以此处该错误可以忽略
