Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Hi, I have a problem regarding setting up a tape drive. I have
consulted the supplier (HP) but they don't seem to understand the
I can use the tape drive, forward, rewind it, copy things to/from it
but it detects it as a 2GB instead of 200GB drive. I think the problem
is on the Density Code (0x40) that applies for a DLT1 drive, not for a
The specifications are as follow:
OS: SLES 9 (SuSe Linux Enterprise Server)
Kernel Ver.: 2.6.5-7.97
PC: Dell Power Edge 1800
SCSI Card: Adaptec AHA 2940W / 2940UW
SCSI Card Driver: AIC7xxx
Tape Drive: HP StorageWorks Ultrium 215 (internal)
Tape Drive Driver: mtst (provided by SLES 9)
The "mtst -f /dev/nst0 status" command gives me the following message:
SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 0 bytes. Density code 0x40 (DLT1 40 GB, or Ultrium).
Soft error count since last status=0
General status bits on (1010000):
On hp's site, it says that this tape drive is fully compatible with
this Linux version, so the "mtst" driver should comply it:
I'm not familiar with Suse, but I know solaris has presented a similar problem when the drive description in st.conf is not present or correctly defined it will default to a generic driver. You might look for a man page on st.conf to see how this info should be formated or search HP's site for an appropriate st.conf entry.
Finally I discover that the open source backup software I was using was forcing to set the tape capacity, instead of quering the driver, so I change it and it works now.
Anyway, thank you very much for your answer.
