2.13.2 Moving an Existing Database Server to a Different Cluster

You can repurpose an existing database server and move it to a different cluster within the same Oracle Exadata Rack.

1. Remove the database server from the existing Oracle Real Application Clusters (Oracle RAC) cluster.
   1. Stop Oracle Grid Infrastructure on the database server.

      $ Grid_home/bin/crsctl stop crs
      

   2. Remove the database server from the cluster by completing the steps in Remove the Database Server from the Cluster.
2. Determine if the database server that is being repurposed needs to be reimaged.

   Check the image label of the existing database servers in the cluster to which you want to add the database server. If the image label of the database server being added does not match the image label of the existing database servers in the cluster, then reimage the database server being added. Complete the following tasks:

   • Contact Oracle Support Services
   • Download Latest Release of Cluster Verification Utility
   • Image the Database Server
   • Configure the Re-imaged Database Server

   If an upgrade is required, the upgrade may be performed using patchmgr. See Updating Exadata Software for details.

3. Add the database server to the cluster.
   Complete the following tasks:

   • Prepare the Re-imaged Database Server for the Cluster
   • Apply Oracle Exadata System Software Patch Bundles to the Replacement Database Server
   • Clone Oracle Grid Infrastructure to the Replacement Database Server
   • Clone Oracle Database Homes to the Replacement Database Server
4. Download and run the latest version of Exachk to ensure that the resulting configuration implements the latest best practices for Oracle Exadata.
