Restarting services on 2 active active clustered nods

  • What will happen in restarting sql server instances on 2 active active clustered nodes?

  • if you restart at the same time nothing as there will be no failover partner available for each instance!

    Just out of interest how many nodes are in the cluster?

  • Hi,

    We restart our active/active clusters at different times to allow the instances to failover and then allow failback for the instances so they end up on the correct node after the patching wave.

  • Be it Active - Active or Active - Passive, Failing over of the sql instance will depend upon the possible owner.

    Whichever node is selected in Possible owner section, instance can failover on that node in case of failure.
