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?

Subject: Re: [Bacula-users] max. 400GB on Tape
We have our own physical backup server running Red Hat Linux 6 with
5.0.3 to a Tandberg T24 Tape Library
with one LTO-5 Tape drive with an uncompressed capacity of 1.5 TB.
Only Bacula is writing to this no. No other application uses it.
When about 400GB capacity is reached, then tape will be marked full
switches to the next tape in the pool.
Where can I configure to use the whole 1.5TB capacity.
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.
