Modify SCAN IP address

Let us say the scan IP address is modified (without change in subnet mask) then follow these simple steps to reconfigure the scan

1. Add the additional ips to the /etc/hosts (of all hosts) (Optional only when DNS is not configured)
2. $ORACLE_HOME/bin/srvctl modify scan -scanname <scan-name>
   1. This command need to be run as ‘root‘
3. As grid user run:
   1. srvctl modify scan_listener -update
   2. srvctl stop scan_listener
   3. srvctl start scan_listener
   4. srvctl status scan_listener
