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.
Remapping Tape Drives
The Rescan action on the Libraries tab in the Management task area causes DPM to examine
the tape drives that are attached to the DPM server and update the information displayed on
the Libraries tab. The Libraries tab displays each stand-alone tape drive and each tape library
and its drives.
When the physical state of the tape drives does not display correctly in DPM Administrator
Console, you need to remap the tape drive information. For example, drives from a tape library
are listed as stand-alone tape drives, a drive for Library 1 is listed as belonging to Library 2, or a
stand-alone tape drive is reported as a drive within another library rather than as a stand-alone
tape drive.
Note
If a tape drive is not mapped correctly, jobs that require the tape drive that is incorrectly
mapped will fail.
To correct the tape drive mapping, you must create a file named DPMLA.xml with the correct
information, and then click Rescan. A template file for drive remapping,
LADriveRemappingTemplate.xml, is added to the DPM server when you install DPM.
To create DPMLA.xml, open LADriveRemappingTemplate.xml from Microsoft Data Protection
Manager\DPM\Config in an XML editor or Notepad, follow the instructions in the template file, and
then save the file as DPMLA.xml in the Microsoft Data Protection Manager\DPM\Config folder.
Important
You should not make changes to LADriveRemappingTemplate.xml because future
updates to DPM might include changes to the template file. If you modify
LADriveRemappingTemplate.xml, updates to DPM cannot replace the template file.
The following is an example of the contents of a DPMLA.xml file that maps a drive that is reported
as a stand-alone tape drive into a library at the drive bay 0 in the library:
<?xml version="1.0" encoding="utf-16"?>
