Database Software

hello,

im trying to installing in Redhat 5.3 an Oracle 11.2 database following the next file:
http://www.oracle-base.com/articles/11g/OracleDB11gR2RACInstallationOnOEL5UsingVirtualBox.php#install_grid_infrastructure

All was ok but i cant ping rac2-vip but can ping rac1-vip (rac1, rac2, rac1-priv and rac2-priv its ok to ping too)

[oracle@rac1 ~] ping -c 3 rac2-vip
PING rac2-vip.localdomain (192.168.2.112) 56(84) bytes of data.
From rac1.localdomain (192.168.2.101) icmp_seq1 Destination Host Unreachable
From rac1.localdomain (192.168.2.101) icmp_seq2 Destination Host Unreachable
From rac1.localdomain (192.168.2.101) icmp_seq3 Destination Host Unreachable

--- rac2-vip.localdomain ping statistics ---
3 packets transmitted, 0 received, +3 errors, 100% packet loss, time 1999ms, pipe 3

[oracle@rac1 ~] ping -c 3 rac1-vip
PING rac1-vip.localdomain (192.168.2.111) 56(84) bytes of data.
64 bytes from rac1-vip.localdomain (192.168.2.111): icmp_seq1 ttl=64 time=0.040ms
64 bytes from rac1-vip.localdomain (192.168.2.111): icmp_seq2 ttl=64 time=0.043ms
64 bytes from rac1-vip.localdomain (192.168.2.111): icmp_seq3 ttl=64 time=0.041ms

same result if i try from rac2.

my /etc/hosts i think is correct in both nodes is the same:

[oracle@rac1 ~] cat /etc/hosts
#Do not remove the following line, or various programs
#that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6

#public
192.168.2.101 rac1.localdomain rac1
192.168.2.102 rac2.localdomain rac2
#Private
192.168.0.101 rac1-priv.localdomain rac1-priv
192.168.0.102 rac2-priv.localdomain rac2-priv
#Virtual
192.168.2.111 rac1-vip.localdomain rac1-vip
192.168.2.112 rac2-vip.localdomain rac2-vip
#SCAN
192.168.2.201 rac-scan.localdomain rac-scan
192.168.2.202 rac-scan.localdomain rac-scan
192.168.2.203 rac-scan.localdomain rac-scan


please, give me any ideas or explain my why it is wrong



Thanks in advance
