Hi Expert,
I have following infrastructure at par. where i have 3 server in WFC(Windows Failover cluster) Win2012 and out of 3 servers two servers are active/passive cluster with SQL Instance hosted on it and i have created AG group for 3 users database and setup Sync Replica on 3rd server within my WFC cluster.
I have SQL VIP(Virtual Server Name) for cluster and also i have AG Listener resources also on the cluster. Now this cluster is attached to SAN single.
3rd server where we kept sync replica its storage is not coming from SAN it has local storage attached to it.
Now we know we have single point failure if SAN goes down My SQL Server 2node active passive cluster instance will also come down.
Now in this kind of event will my AG Listener can be online on WFC even if SAN is down so that it can redirect connection to the 3rd server where it has sync replica copy.
Also if in case Listener will not be able to be online in event of SAN failure what would alternative path we consider here
your valuable suggestion and time are most welcome.
Thank you very much..
