Adding an IBM Spectrum Archive Enterprise Edition (EE) node in an IBM Spectrum Scale cluster

Use this information to add an IBM Spectrum Archive Enterprise Edition (EE) node in an IBM Spectrum Scale cluster.

1. Use the installation toolkit to install IBM Spectrum Scale and create a cluster.

   For more information, see Using the installation toolkit to perform installation tasks: Explanations and examples.

2. If the node on which IBM Spectrum Archive Enterprise Edition (EE) is going to be installed is running on RHEL 6.x, install IBM Spectrum Scale packages on that node manually using the RPMs from a protocol node.
3. Add the IBM Spectrum Archive Enterprise Edition (EE) node to your cluster at any time after the cluster is created.

   For more information, see Adding nodes to a GPFS cluster.

4. Before installing IBM Spectrum Archive Enterprise Edition (EE), enable Data Management API (DMAPI) on the file system to be used with IBM Spectrum Archive Enterprise Edition (EE).
   1. Unmount the file system to be used with IBM Spectrum Archive Enterprise Edition (EE).
      Note: If this file system is also used for protocols, you cannot unmount the file system unless you issue the mmshutdown command on all protocol nodes.
   2. Enable DMAPI using the mmchfs Device –z yes command.

      In this command example, Device is the device name of the file system.

   3. Mount the file system again and issue the mmstartup on all protocol nodes if you used the mmshutdown command in a preceding step.
5. Install and configure IBM Spectrum Archive Enterprise Edition (EE).

   For detailed information on using IBM Spectrum Archive and IBM Spectrum Scale together, see Active Archive Implementation Guide with Spectrum Scale Object and IBM Spectrum Archive Redpaper. Chapters 2 and 3 of this document contain specific details about cluster configuration and how to add the IBM Spectrum Archive node to the IBM Spectrum Scale cluster.
