Change Oracle SCAN VIP

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
