Thank you for correcting my mistake !
It is very bad that I missed out the important information
Even now I am not getting the 3 SCAN IPs when I type nslookup ora-rac1-scan on RAC Nodes
I performed the below on host machine:
-- saved all the RAC specific IPs in /etc/hosts file
-- started dnsmasq service and also stop and restart too
-- uncommented the 3 SCAN IPs
After this I logged in to RAC Node and typed nslookup ora-rac1-scan and the output was not 3 IPs
Just to check the output and confirm vboxnet0 (Virtual box network adapter) is working or not I typed " route" on host machine and the
output was "192.168.56.0". The vboxnet0 Virtual box network adapter is working.
The hosts file on the host machine is
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain
82.x.x.x <host> <host>.xyz.com
64.x.x.x <host> <host>.xyz.com
192.168.56.101 ora-rac1.localdomain ora-rac1
192.168.56.102 ora-rac2.localdomain ora-rac2
192.168.1.101 ora-rac1-priv.localdomain ora-rac1-priv
192.168.1.102 ora-rac2-priv.localdomain ora-rac2-priv
192.168.56.103 ora-rac1-vip.localdomain ora-rac1-vip
192.168.56.104 ora-rac2-vip.localdomain ora-rac2-vip
192.168.56.105 ora-rac1-scan.localdomain ora-rac1-scan
192.168.56.106 ora-rac1-scan.localdomain ora-rac1-scan
192.168.56.107 ora-rac1-scan.localdomain ora-rac1-scan
and /etc/resolv.conf on host is
# Generated by NetworkManager
and /etc/resolv.conf of RAC Node 1 and Node is with
and /etc/hosts files of RAC Nodes are with SCAN IPs commented
When I ping " ora-rac2 " and "ora-rac2-priv" the machines are communicating with 0% packet loss.
Do not know where the problem exists?
