Error code 0x84B20001 2008R2 SP 1 failed in cluster :


  •  I tried to install SP1 in SQL Server 2008R2 .First I got this Error code 0x84B20001." A failure was detected [SQL_Replication_Core_Inst, SQL_Engine_Core_Inst,MPT_AGENT_CORE_CNI,]" and I tried to repair  SQL Server .

    In my case:  Node (B - passive and I  tried to install SP1) and Node (A- active) . I disconnect node B and let node A be a owner . 

     My repair failed for Database Engine and SQL Server Replication and in summery.txt suggest  " The SQL Server feature 'SQL_Engine_Core_Inst' is not a supported state for repair , as it was never successfully configured on remote node A. To continue , remove the specific SQL Server  node A from the cluster ."

    what to do now please suggest me.

  • Hi whatsUpYo,

    Before you repair for SQL Server failover clusters, review the following important information:

    Repair must be run on individual cluster nodes.
    To repair a failover cluster node after a failed Prepare operation, use Remove node and then perform the Prepare step again.

    For more information, see How to Add or Removed Nodes in a SQL Server Failover Cluster:
