    Thanks Ciro and Sandy.

    The solution was to add these lines to /etc/init.d/boot.local:

    for x in /proc/driver/cciss/cciss[0-9]*
    do
      echo "engage scsi" > $x
    done

    after restarting the system detected the tape unit with these messages:

    st: Version 20040403, fixed bufsize 32768, s/g segs 256
    BIOS EDD facility v0.16 2004-Jun-25, 3 devices found

      Vendor: HP Model: Ultrium 2-SCSI Rev: F48D
      Type: Sequential-Access ANSI SCSI revision: 03
    Attached scsi tape st0 at scsi0, channel 0, id 0, lun 0
    st0: try direct i/o: yes (alignment 512 B), max page reachable by HBA
    4294967295
    Attached scsi generic sg0 at scsi0, channel 0, id 0, lun 0, type 1

    I've some doubts about the above messages.

    Does these missing error handlings to cciss's driver will affect the backups
    i'll make?
    Is it correct to assume the tape is /dev/st0 instead of /dev/sg0 ?
    Wich is the speed of this tape unit ?
    I want to backup the all system for recovering in case of hard disk failure,
    what do you advise me, tar, dump or something else ?

    Best regards

    Oxiel
