You can add tape libraries and stand-alone tape drives to System Center Data Protection Manager (DPM) to enable short-term and long-term data protection on tape. The tape libraries and stand-alone tape drives must be physically attached to the DPM server.
After you attach a new tape library or stand-alone tape drive to your DPM server, you must perform a Rescan operation before the DPM server can identify them. When you perform a Rescan operation, DPM examines the tape libraries or stand-alone tape drives that are attached to the DPM server and updates the information that is displayed on the Libraries tab in DPM Administrator Console. The Libraries tab displays each stand-alone tape drive, and each tape library and its drives.
You use the Rescan operation on the Libraries tab to check for and refresh the state of all new tape libraries and stand-alone tape drives when you make changes to your hardware.
|If the stand-alone tape drives listed on the Libraries tab in DPM Administrator Console do not match the physical state of your stand-alone tape drives, see Managing Tapes. For example, if drives from a tape library are listed as stand-alone tape drives, or if a stand-alone tape drive displays incorrectly as a drive in a tape library, you need to remap the tape drive information.|
To configure tape libraries
In DPM Administrator Console, on the navigation bar click Management, and then click the Libraries tab.
In the Actions pane, click Rescan.
The Rescan operation might take several minutes to complete. DPM will add any library jobs to the queue that began during the Rescan operation. If a library job is already in progress when the Rescan operation begins, the Rescan operation will fail.
