I know in unix everything is a file.

What does device file and /dev directory do when i configure tape drive.

And in windows what does port,bus,target,LUN does?

Those are the hardware addresses that the OS uses for access to the tape drive.

If you need more info, you need to ask on OS forums...

You have OS-related questions, not NetBackup...

As an application, NetBackup has no direct access to a device, instead relying on the operating system (OS) to handle any communication with the device. This means that during a write operation NetBackup asks the OS to write to the device and report back the success or failure of that operation.

If you need to know more about hardware addresses at OS level, you can read through these (and other links found via Google):
