INS-40719, SCAN name problem when installing Grid Infra

Cuong PhamMar 28 2012 — edited Mar 28 2012
Hello everyone.
I have a big trouble when installing Oracle Grid Infrastructure 11gR2. When I run into Cluster configuration, I meet the following error message:
Broadcast message from oracle (pts/2) (Wed Mar 28 16:36:14 2012):

Cause - The installer could not find the IP addresses you selected as SCAN addresses. This may be because they are assigned to another system, or the IP addresses are not listed in the DNS or hosts files as assigned to this domain name.  Action - Enter resolvable IP addresses to use as SCAN addresses.
I tried to install Grid Infra on two Vmware machines, these are configurations on those machines:

On vm4:
- eth0, eth2, eth3: configured to bridged network (subnet: 192.168.50.0), that connected already to vmnet bridged interface
- eth1: configured to host only network (subnet: 192.168.150.0), that connected already to vmnet host-only interface
*/etc/hosts:*
192.168.50.185  vm4.vzone       vm4
192.168.150.104	vm4-priv.vzone	vm4-priv
192.168.150.105	vm5-priv.vzone	vm5-priv
127.0.0.1	localhost.localdomain localhost
On vm5
There are 4 NIC cards (same to vm4 machine):
- eth0, eth2, eth3: configured to bridged network (subnet: 192.168.50.0)
- eth1: configured to host only network (subnet: 192.168.150.0)
*/etc/hosts:*
192.168.50.184	vm5.vzone	vm5
192.168.150.104 vm4-priv.vzone  vm4-priv
192.168.150.105 vm5-priv.vzone  vm5-priv
127.0.0.1	localhost.localdomain localhost
On private DNS server:
*vzone.db*

	3H;

183	IN PTR	vm3.vzone.
185	IN PTR	vm4.vzone.
184	IN PTR	vm5.vzone.

186	IN PTR	vm-scan.vzone.
210	IN PTR	vm-scan.vzone.
187	IN PTR	vm-scan.vzone.
I can ensure the success of these command:
nslookup vm4
nslookup vm5
nslookup vm-scan : resolved to 4 IP address with round-robin
When I tried to install Grid Infra, the Installer error on Cluster configuration step, I found these log contents from log file:

Can you help me to detect this problem? I've search clearly on Google but cannot found something helpful. By the way, can you give me some suggestion of step to install Oracle DB 11gR2 RAC:

- should we install Grid Infra for standalone server or RAC ?

Any suggestion is appreciated :)
