I have provided the below steps ,scan and vip address
change, IP address for scan should be configured in DNS is round robin fashion
and should be added in /etc/hosts.
VIP address should be added in /etc/hosts , needs to be
assigned in DNS entry.
Changing Virtual IP / Virtual Host Name
-- CHANGING NODE VIP FROM 192.168.2.220 TO 192.168.2.330 ON
ravs1
-- SINCE NODE VIP IS PART OF NODE APPS ONE NEEDS TO MODIFY
THE IP ADDRESS ON OS LEVEL AND THEN USE SRVCTL TO MODIFY NODEAPPS

So to change to SCAN IP / Name one has to first populate the
changes on DNS to take it into effect. Once the changes are in effect, one can
modify the SCAN resource in OCR as follows. Remember SCAN acts as cluster entry
point and load balancing process , the restart to SCAN will require a brief
outage
[oracle@ravs2 ~]$ srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
