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

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

1. Use the installation toolkit to install IBM Storage 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 Storage Archive Enterprise Edition (EE) is to be installed is running on RHEL 6.x, install IBM Storage Scale packages on that node manually by using the RPMs from a protocol node.
3. Add the IBM Storage 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 you install IBM Storage Archive Enterprise Edition (EE), enable Data Management API (DMAPI) on the file system to be used with IBM Storage Archive Enterprise Edition (EE).
   1. Unmount the file system to be used with IBM Storage 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 by using the mmchfs Device –z yes command.

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

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

   For detailed information on using IBM Spectrum Archive and IBM Storage 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 Storage Scale cluster.
