Configure DDS

Before you start configuring DDS, verify if you have installed the following options:

To configure your system to use DDS

  1. Open the fibre switch.

    All of the NAS servers and Arcserve Backup servers detect all of the attached devices and each other.

  2. Configure a SCSI bridge or router such that it does not expose itself as a SCSI array device.

    NAS servers may not be able to connect to the SCSI bridge or router if it exposes itself as an array device.

  3. Verify that all NAS and Arcserve Backup servers can detect all devices.
  4. Ensure that online TLUs are in the ready state.
  5. Confirm that the devices are shared by enabling the Tape Engine Debug Log in Server Administration when starting the tape engine.

    This log (labeled tape.log) provides you with details about devices that are shared and not shared. The details can be found in the List Dynamic Device Sharing Device Map section of the Tape Engine Debug Log.

  6. Verify that the tape drive is not already opened and in use by another NDMP session.

    Note: Shared SCSI devices are displayed under the local adapter. The group and adapter icon will be marked as shared.
