MS SQL 2012 with 2 nodes Cluster

  • Hi,
    I have a question regarding sql 2012 cluster 2 nodes
    OS: Windows 2012 with AD
    SQL: MS SQL Server 2012
    Cluster: 2 nodes

    First time i'm going to install sql 2012 cluster for 2 nodes, like A and B.  My question.

    Shall i install cluster on both machine in A and B?
    Shall i create ms sql database on both machine?
    Shall i restore database on both machine ? like A and B

    Last,  what are they requirement for installation such as Cluster Name, Domain admin, or Administrator on Domain Control admin rights?
    Only on MS SQL Server side question.
    Network card and Heartbeat, cluster ip, i have already.

    Thank you

    Both machines need to have cluster services installed.  
    You cannot install the databases on both machines.  A cluster is shared storage.

    If you assassinate a DBA, would you pull a trigger?

  • Thank you, real appreciate your answer.
    Ok, on both A and B machine i have to install cluster, thank you.

    What about datebase? restore? on both machine A and B?
    or singel machine? 
    So you mean, i have to create database on A machine and restore date, no need for Machine B?

    Thanks

    Your questions tell me that you have no understanding of how clustering works.  

    In a two-node active/passive cluster, SQL is installed on BOTH nodes.  The articles I provided gave very good details on this.  Did you read them?

    During installation of SQL on a cluster, one of the things you provide is the virtual name for SQL server.  
    The virtual name is where you would restore these databases to.  The databases do not live on BOTH nodes.  The storage is shared between the nodes.  

    I suggest that you create your storage, make sure it can be accessed by the active node when you fail the cluster back and forth between the nodes.
    You also need to cluster MSDTC.

  • First off what type of HA is being implemented here?  A typical failover cluster where you have shared storage, and one of the nodes has nothing running eg an Active Passive cluster.  Or are you trying to implement Always On Availability Groups.

    The two while utilize WFC are completely different to setup after the cluster has been configured.

  • I am using Active and Passive cluster in 2 nodes
