Hello Team
We have to configure AlwaysOn to an already existing Failover Cluster Instance (FCIs) like in the below architecture.
How is it now -
Setup:
FCI-1: SQLFCIPRIMARY\Inst_A
FCI-2: SQLFCIDR\Inst_B
Nodes
PrimaryNode1
PrimaryNode2
DRNode1
DRNode2
Each of the above FCIs are 2 node clusters as shown the above figure. All the 4 nodes are in the same data center.
Since all the instance should be in WSFC for setting up AlwaysOn AG, I tried adding the seconday node to the existing cluster in Primary. But it is throwing an error saying"The computer 'DRNode1' is joined to a cluster." While this is expected since DRnode1 and DRNode2 are already participating in clustering, I would like to know how to get around with this issue. I have researched (actually googled ) quite a bit but do not find an applicable solution for this. One way is to remove the secondary node (DRNode1 or 2) from the cluster but I guess it doesn't make sense in my case since I want to create a AlwaysOn solution between two FCIs.
What I am not able to do -
Ideally I would like all the 4 nodes showing up in Primary Failover Cluster Manager.
Thanks a lot in advance.
