Hi,
ClusterService ======> It hold web IP ressource & online on one node
( What is the use of this IP & is should be online two hosts ?)
>>> ClusterService service group will be online on any 1 node in the cluster at any point. This IP address is a cluster IP which was intially intended to have a webGUI access to cluster management web console. This IP address is also used in GCO setup by WAC resource to find status of cluster on replicated site.
1) Do I need to link my datafiles SG to any other SG ?
>>> I would expect that oradata_sg is dependent on CVM. You can run "hagrp -dep" to check.
2) Do i need to configure any other res,SG for network ? (I guess clusterware taking care vIP)
>>>not really, you would have a PrivNIC resource configured in main.cf which will the IP for clusterware.
3) In main.cf file oradata_sg & vrts_vea_cfs_int_cfsmount1 both poing for datafiles mountpoint. can I remove vrts_vea_cfs_int_cfsmount1 sg ?
>>> This should not be the case, you should not have 2 different resources pointing to same resource. This is possible & accepted in case of network cards where you can have proxy resource however for mount resource, it doesn't look to be recommended. How did this happen ? was anything done manually ? Also can you paste main.cf here ?
<< I would suggest to change server names while pasting the output >>>
