In my previous post -- changed Oracle cluster IP/VIP address. I mentioned how to change those IPs. But for some reasons that SCAN VIP did not change. Here are the steps to change it: 1> Make sure that the SCAN VIP hostname can be resolved.      nslookup < SCAN_name> 2> Become root and set ORACLE_HOME environment [oracle@host1 ~]$ su - Password: [oracle@host1 ~]# export ORACLE_HOME=/u01/app/oracle/grid [oracle@host1 ~]$ srvctl config scan SCAN name: linpe-cluster, Network: 1/9.55.49.0/255.255.255.0/eth0 SCAN VIP name: scan1, IP: /linpe-cluster/ 10.10.46.183 [oracle@host1 ~]# modify scan -n linpe-cluster [oracle@host1 ~]$ srvctl config scan SCAN name: linpe-cluster, Network: 1/9.55.49.0/255.255.255.0/eth0 SCAN VIP name: scan1, IP: /linpe-cluster/ 9.55.49.183
