Configuring Devices: An Overview

After tape devices have been physically attached and defined to your server system, you must then configure them to TSM so that TSM can use and manage the devices and their media.

Sequential access devices typically require that the following steps be performed so that TSM can use the devices.

  1. Attach the device to the server system.

    After you physically attach the device to your system, you must ensure that the appropriate device driver is set up. For autochanger devices, you must ensure that you set up the SCSI pass-through device driver. See Before You Start: A Few Words about Device Drivers.



    Attach the device to the server system.

  2. Define the device to TSM.

    The administrator defines the storage objects that represent the physical device and media: library, drive, device class, storage pool, and storage volume. For an introduction to the TSM storage objects, see The Tivoli Storage Manager Storage Objects and Configuring Devices.



    Define the device to TSM.

  3. Define the TSM policy that links client data with media for the new device.

    The administrator defines or updates the TSM policy objects that will link clients to the pool of storage volumes and to the device. Do this by using the new storage pool as a destination for backed up, archived, or space-managed client data. For an introduction to the TSM policy objects, see How Tivoli Storage Manager Stores Client Data. For a description of the standard policy that is installed with TSM, see Using the Standard Policy.

    An alternative is to simply place the new storage pool in the storage pool migration hierarchy by updating an already defined storage pool.



    Define the TSM policy.

  4. Register clients to the policy domain defined or updated in the preceding step. This step links clients and their data with storage volumes and devices.



    Register clients to the policy domain.

  5. Prepare volumes for use by the device. At a minimum, you must label volumes for the device. For automated libraries, you must also add the volumes to the device's volume inventory by checking in the volumes.

For an example of setting up a manual library, see Example of a Manual Library: Setting Up Two 8mm Tape Drives. For an example of setting up an automated library, see Example of an Automated Library: Setting Up an 8mm Autochanger.
