Never mind.  After changing to SCSI ID to 6, plugging the drive into the other SCSI port, and rebooting the server, the drive was detected by Backup Exec.  "Problem" solved.
I just installed Windows Server 2008 R2 on my PowerEdge 2900.  I have a PowerVault 110T (it also says Ultrium LTO 3 on the front) which I want to use with Symantec Backup Exec 2010.  However, Backup Exec does not see the tape drive.  Do I need a driver for the tape drive?  If so, where can I find that driver.  I can only find a driver for Windows Server 2003 and Windows Server 2003 x64 on the Dell driver downloads for this unit (Service Tag Removed by moderator).  Any help will be greatly appreciated.
Need Driver for PowerVault 110T (LTO-3) for Windows Server 2008 R2
