Moving from mirroring to AlwaysOn for SQL Server 2012

  • I am setting up two test servers loaded with SQL Server2012 Enterprise edition, one in a datacenter on the East Coast and one server in a datacenter on the West Coast. As I understand it and I have configured both serves to turn on Filover clusterig. When I stepped thru the process on the first server (Primary server) when I got to the dialog screen that asked for "Select Servers or a Cluster" I am not sure if I am to enter just the server I am working on or to enter both servers (one on the east coast and one on the west coast) that will make up a named cluster.

    On the next screen it ask to name the cluster which I did and then it list the two networks the servers are on and ask for an IP.I am not sure if I should just pick the first available IP address that is not used or be concerned that the network admins need to be consulted. I went ahead and ran thru all the steps and the process completed OK. I logged into what I hope to be my standby machine and tried to see if it recognized the cluster I set up on the primary server and it came back with an error.

    So I guess what I a asking is if I just want to set up two remote servers so that if one fails the other server will come online am I talking about one node server cluster or am I talking about a two node server failover cluster and should I be able to see the named cluster from both modes when configuring/managing:unsure:

    When creating the Windows cluster you need to select all nodes that will be a part of the cluster.

    You need to consult your sys admins to ensure the cluster virtual IP and network name fit with their standard and are not in use

  • I have been at this for several days and have been able to complete the windows cluster. I have created an availability group with my two nodes. I have three databases that I have included as part of the AG. I have two Replicas one Primary and one Secondary. I went thru the AG setup and everythin passed. But once I tried to join the databases to the AG I got the error :

    The connection to the primary replica is not active. The command cannot be processed. (Micorsoft Sql Server , error:35250) I have Googled tis error but no luck in finding out what the actual issue is and how to correct???

    Anyone have an idea ( I feel like am so close)

  • You may to check network connectivity issues. Perhaps the default port is hung from one of your prior problems. Check for any routing/firewall issues. Good luck.

  • Thanks...

    I checked the both servers and sure nuff the secondary server had its firwall enabled whereas the primary server had its firewall disabled. I disabled the firewall on the secondary server then joined the databases to the AG and everything is now working as advertized...

    Thanks for pointing me in the right direction:hehe:
