I am planning to implement ‘Always On’ functionality for reporting purpose on a multi node fail over cluster (active – active cluster), each node has two instances, with one instance/node running under normal situation.
Node1 – instance 1, instance 2 ( sql port 4567 , 4569 )
Node2 – instance 2, instance 1 ( sql port 4569 , 4567 )
I would like to have a copy of few of our databases on Node2\ instance 2 without any fail over. when I tried this first thru the wizard I got the following error “ Failed to create, join or add replica to availability group XXXX, because node Node1 is possible owner for both replica Instance1 and instance2. If one replica is a fail over cluster instance, remove the overlapped node from its possible owners and try again (MS SQLError: 19405 ) “.
I know the reason we are getting this error, but if I remove one of the node from being the owner of these instances, i will lose the ability to fail over to the other node. Is there any work around for this. All i am trying to achieve is to create a read only instance of few of our database on node2\instance2 just for reporting purposes.
Thanks in advance
