L&TT doesn't detect HP StorageWorks Ultrium 448 SAS

[Genady Kruglenko]

Hello.

I have a following configuration:
Proliant DL580G5 Server with 1 external Smart Array P400 controller and HP StorageWorks Ultrium 448 SAS Tape Drive.

OS: Windows Server 2003 R2 x64
HP StorageWorks Tape Drivers version: 1.2.0.0
Backup Software: Data Protector Express Single Server 3.50 SP2
L&TT version: 4.5 SR1

OS and DPE detected tape drive successfully, but L&TT doesn't detect it. I get "Scan complited with errors" message when I start L&TT and click "Continue" (NT Miniport Mode selected).
I try to stop DPE service before, but it doesn't help.

Could anyone help me?

I have attached L&TT logfile.
