Data Protector Express Single Server Edition error codes, explanations & solutions

[Curtis Ballard]

Sergey,

I would normally say that your problem is caused by an application however it sounds like you understand the applications and will have checked that.

The connection to the library and the drive is over an identical path and the communication to the library appears fine which suggests that there is a software problem somewhere on the server causing you to not be able to connect to the drive.

Usually that can be traced to some application such as Windows Removable Storage Manager or a backup application. If you can't find anything using the device you can go to device manager and disable the tape drive. After disabling the tape drive try L&TT again and it should work fine. If L&TT works with the tape device disabled then some drive or application is causing the connection problem. If L&TT can't work with the disabled drive then we need to dig a bit deeper.

Wich OS you have?

if you are running on windows, make sure there's no "unknown medium changer" under device manager.

And also make sure you have a HBA not a smart array controller.
