Database Software

Hi all,

I am try to install G.I. 11gR2 with 2 node (GNS, SCAN, ASM) and Cluster Verification Utility fail with error.
"
INFO: Checking Single Client Access Name (SCAN)...
INFO: Checking name resolution setup for "sky-scan.cluster.oracle.cloud"...
INFO: ERROR:
INFO: PRVF-4664 : Found inconsistent name resolution entries for SCAN name "sky-scan.cluster.oracle.cloud"
INFO: Verification of SCAN VIP and Listener setup failed
"
Before this everything is ok , everything is clean.
I have DNS server (separate VM) installed and in same machine I have DHCP server.

DNS DHCP server OS= OEL6.1
RAC nodes OS = OEL5.7

scanName=sky-scan.cluster.oracle.cloud
clusterName=sky-cluster
GNS=true
gnsSubDomain=cluster.oracle.cloud
gnsVIPAddress=192.168.7.150

before install tested with command
*[grid@rac1 ~]$ ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -verbose*
and in here also everything is fine.

Also I try to nslookup everything and its also fine.
If anyone knows where are my mistake please help me.
As I am not a network services guy I think my mistake is somewhere in dns
configuration maybe in subdomain but I can't find it :(
