Always on 2012 on Window server 2008r2

  • Hi all,

    I am trying to setup alwayson on 2008r2 server on 2 instances in the same machine fort testing purpose. I installed 'Failover Cluster Manager' now I don't see 'Nodes' to add up.

    Should I run 'Validate a configuration Wizard'? or something else.. Can't find online to setup 'Alwayson' from the scratch!!!!

    Last thing, Will I able to setup 'Always on' on same server but different instances like mirroring? or has to be different servers?

    Thanks

  • check my stairway article on this site starting at this link[/url] for more help

  • Thanks for your reply Perry. Looks like I need 2 nodes (servers). Is it possible to setup like mirroring on same sever with 2 instances? if, so how do I add another node?

  • you can create a failover cluster instance on a cluster with 1 node that's fine, not much use but can be done.

    For AlwaysOn availability groups you will need at least 2 nodes in the cluster, this will scale up as you require further replicas to be joined to the AO group

  • Now I have 2 test servers. Do I need a shared storage somewhere else? Is it possible to make shared storage in one of the server which is included in the cluster?

  • Have you read my stairway??
