this is steps that I have completed:
1/ window cluster 2012 created
2/ installed sql server 2012 (I selected new sql server stand-alone installation or add features to an existing installation) for both server (server 1 and server 2)
3/ next installation for sql server failover cluster 2012 is on top of sql server 2012. I am struggling with this installation and cluster node is failing. Please give me the guideline/step that fully working.
There are articles that i found, showing how to setup sql server failover cluster 2012. alwayson new feature configuring/manageing will be after I installing or before installing sql server failover cluster 2012?

thanks

If I am interpreting your post correctly are you saying that you have two physical servers participating in a windows cluster.

On each node you've a SQL server installation you plan to use with always on availability groups.

In addition to these standalone instances you are trying to install a 2 node SQL cluster on the same physical severs.

Is this correct? If so yes its possible but you will require local storage on each node to support the servers utilising always on, and shared storage presented which can be used for the failover SQL cluster.

Also you wont be able to join the clustered instance to any AO groups you create since the clustered instance spans the same nodes as the stand alone instances.

If your plan was to install standalone SQL instances on each node and then 'upgrade' them to clustered instances, there is no supported process to make this work.

You can continue to use the instances you installed as standalone SQL instances. If you want to have a clustered SQL instance then you will need to install a new SQL instance to specifically be a SQL clustered instance.
