Group online whereas resource offline:geocluster

Hi Cluster Gurus,

I am working on GEOCluster porting. We ported our product on MSCS cluster and planning to port the same on GEocluster.
Note that we are making our product just aware of cluster(specially Resource group) and hence use few MScluster API viz.

"OpenClusterNode"
"GetClusterNodeId"
"GetClusterNodeState"
"CloseClusterNode"
"OpenClusterGroup"

RG=resource-group

I need some help on below doubts,

1) Does any of the above API's behaviour chnaged because of GEOcluster?
2) Is it possible to have resource-group state online even if one of its resorces in offline state ( I believe it s partial online in MSCS cluster)?
3) To get all associated nodes (preferred owner) for a resource-group, the API "ClusterGroupOpenEnum()" with CLUSTER_GROUP_ENUM_NODES as parameter is sufficient ?
Or
Using RG get all resources using ClusterGroupOpenEnum() ClusterGroupEnum() , then for each resource get member-nodes using ClusterResourceEnum()and then cross verify these nodes with nodes in the cluster setup using ClusterOpenEnum() ?

I appreciate your help on this.
Thanks in advance.

Warm Regards
- Krishna

Multi site clusters, or geographically dispersed clusters are primarily supported by the vendor of the multi-site cluster software.

you should contact the vendor to get the specific info of the product you are using
