Updating Tape Library Information

Applies To: System Center Data Protection Manager 2007

You can update tape library information by using Rescan on the Libraries tab in the Management task area. The Rescan operation performs the following tasks:

  • Checks for new tape libraries and stand-alone tape drives attached to the DPM server.

  • Refreshes the state of all tape libraries and stand-alone tape drives attached to the DPM server.

Rescan can take several minutes to complete. Any library jobs that begin during rescan will be queued until rescan completes. If a library job is already in progress when rescan begins, the rescan operation fails.

If a new tape library or stand-alone tape drive is identified during rescan, DPM adds its information to the Libraries tab.

If you installed a new tape library or stand-alone tape drive on the DPM server and it is not identified during rescan, try the following steps to troubleshoot the problem:

  1. Ensure that the tape library and drives are properly connected.

  2. For SCSI connections, ensure that the logical unit number (LUN) for each device is unique.

  3. Ensure that Device Manager lists all tape libraries and stand-alone tape drives attached to the DPM server.

  4. Ensure the proper drivers are installed for each device.

You should rescan to refresh the state of tape libraries and stand-alone tape drives attached to the DPM server only when changes have been made to the hardware.
