Sun Cluster switching issue

I have installed sun cluster 3.2 on two sprac servers. Configured a failover resource group. Added a LogicalHostname resource to it. LogicalHostname is also added to /etc/hosts with ip address.
I am able to access cluster by share ip used for logical hostname but when i try to switch the resource to other node of cluster, the resource go offline on both node and never switch.

Any help ...
