I have a tape library SONY AIT 150 GB SCSI drive(D81 library). the tape drive recognized by DPM 2010. But when i install the changer, again it shown as a stand alone drive on DPM2010 console. i have made changes on DPMLA.XML file but it is not effective(for example, the serial number of the changer i corrected on dpmla.xml, is not showing on the DPM console and it is showing as a stand-alone drive not showing slots). what can i do???

Your hardware might not be supported by the DPM 2010 software, for more information, read this link:

Your best bet is to contact the vendor of the tape drive (Sony) and ask for their direct support.

What driver are you using for the medium changer for the Sony drive?

I have seen this situation previously with another vendor's library; the problem turned out to be that DPM 2010 did not like the Microsoft "unknown medium changer" driver. Yes, I know that sounds crazy; Microsoft's product did not like Microsoft's generic medium changer driver. But changing the driver from the Microsoft unknown driver to a vendor supplied medium changer driver resolved the problem and got the medium changer and tape drive showing up normally in DPM 2010.
