Hi guys. Can you help me sort out the non-default ports in my 3-node, multi-instance, 2014 AG cluster? HA Node1 holds primary replica of all AG's. Hopefully below presents it clearly. What changes do you recommend?...
HA cluster node 1:
xx36 = SQL Server default port set in Client Protocols TCP/IP Properties
xx38 = Default Instance port, xx38 = Listener 1 port, xx39, Listener 2 port
xx36 = Named Instance 1, xx36 = Listener
xx40 = Named Instance 2, xx40 = Listener
xx42 = Named Instance 3, xx42 = Listener
xx45 = Named Instance 4, xx45 = Listener
xx47 = Named Instance 5, xx47 = Listener
xx49 = Named Instance 6, xx49 = Listener
HA Cluster Node 2:
xx36 = SQL Server default port set in Client Protocols TCP/IP Properties
DR Cluster Node 1:
xx33 = SQL Server default port set in Client Protocols TCP/IP Properties
Notice above that:
-Default SQL Server port not consistent between HA and DR nodes.
-Listener ports set to same as named instance ports in all cases.
-Named Instance 1 has same port as the default SQL Server port.
Also, on HA cluster nodes 1 and 2, the "Listen All" property not same:
-Default Instance, TCP/IP "Listen All" property = No
-Named Instances 1 through 6, TCP/IP "Listen All" property = Yes
On DR cluster node, all instances have "Listen All" property set to Yes.
