frozen service Service group offline after reboot

Hi

I have a service group named redsg running which is online on node1 and and offline  on node 2.

I froze resg and ran hastop -all -force ,and started it back again on both nodes

the service group state is online now on node1 and offline on node2 as earlier

But when i reboot the node the service group goes to offline on both nodes.

Any idea what makes this difference.

Thanks
