Dear John.

On my tape(s) is the following description:
Tandberg Data LTO ULTRIUM LTO 5 Cartridge 1.5 TB, 3.0 TB UNCOMPRESSED.
Thus I think that is an LTO-5 Tape.

On the other hand there exists the same types of tapes from Tandberg as well
in another pool and this backups run very well.
So I think it could not be a problem of the scsi-bus, isn't it?

There is no place to configure to use the full capacity since tapes with hw 
compression have no fixed full capacity. You could fit 800GB on one LTO5 tape 
and 8TB on a second depending on how your data compresses. Just make sure 
someone did not configure to stop after 400GB by putting limits on the volume 
size in the Pool directive. Most likely your problem is you are using an LTO3 
tape, possibly somehow have the tape partitioned or a tape error has occurred. 
With tapes bacula writes to the tape until it hits its first error. When it 
hits that error it marks the tape full. Check your dmesg for scsi errors.
