查看scan ip的状态信息

[grid@rac1 ~]$ srvctl config scan
SCAN name: rac-cluster-scan, Network: 1/192.168.70.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /rac-cluster-scan/192.168.70.130

停止scan_listener ，scan 应用

[grid@rac1 ~]$ srvctl stop scan_listener
[grid@rac1 ~]$ srvctl stop scan

确认 scan_listener,scan 的状态

[grid@rac1 ~]$srvctl status scan_listener
SCAN name: rac-cluster-scan, Network: 1/192.168.70.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /rac-cluster-scan/192.168.70.130
[grid@rac1 ~]$ srvctl status scan
[grid@rac1 ~]$ crs_stat -t | grep  scan
[grid@rac1 ~]$ crs_stat -t | grep  lsnr

在所有节点中 /etc/hosts 文件中修改 scan 对应的ip

[root@rac1 ~] vi /etc/hosts
[root@rac2 ~] vi /etc/hosts

查看srvctl命令所在文件夹

[grid@rac1 ~]$ cd $ORACLE_HOME
[grid@rac1 grid]$ cd bin
[grid@rac1 bin]$ pwd
/u01/app/11.2.0/grid/bin

使用root命令修改scan-ip，即修改为/etc/hosts里面scan-ip对应的ip

[root@rac1 ~]# cd /u01/app/11.2.0/grid/bin
[root@rac1 bin]# ./srvctl modify scan -n rac-cluster-scan

注：-n后面跟的是/etc/hosts下scan的名称

变更后，进行确认

[grid@rac1 ~]$ crs_stat -t | grep  scan
[grid@rac1 ~]$ crs_stat -t | grep  lsnr

测试和查看

[grid@rac1 ~]$ ping 192.168.70.135
[grid@rac1 ~]$ srvctl config scan
SCAN name: rac-cluster-scan, Network: 1/192.168.70.0/255.255.255.0/eth0

SCAN VIP name: scan1, IP: /rac-cluster-scan/192.168.70.135
