Hi Saurabh,
If you are stopping VCS for maintenance and you want the service group online then you should run "hastop -local -force". The -force will leave all service groups online (except for the ClusterService group.)
If you are needing to stop and start the cluster for your maintenance and you do not want the service group to react, I would recommend persistantly freezing the node. That will affect all service groups on the node so you will not need to worry about each group individually. The persistant freeze will survive a restart of HAD on the node. A Temporary freeze will be automatically removed when HAD is restarted on the node.
Thank you,
Wally
