[CentOS] Problem detecting HP Tape Drive

Hello

 I do have problem using Linux with an external HP tape drive. The
server platform is also an HP Server; the server is an HP ML350 G4,
and the Tape drive is a HP Storage Works Ultrium 448 - 1U
Rack-mountable.

 HP Ultrium documentation says two drivers should be automatically
up, sym53c8xx for LSI SCSI interface "st" for tape and /proc/scsi/scsi
should contain information about tape drive, e.g. SCSI ID. However
none of them happened in my case! (document: "UP LTO Ultrium 2-3 -
Unix Config Guide")

 The SCSI adapter is an LSI53C1030. The system has another the same
adapter which is used for hard disk drives.

 The interesting part is, the hard disk are detected and even OS
boots from them, but I can't make the tape drive work. Moreover, in
system boot up, LSI SCSI BIOS displays informations saying there is a
tape drive connected!

 Any one has same experience, suggestion, comments or clues?

I've place a zip file here:
http://msarmadi.googlepages.com/report_files.zip which contains:

- dmesg
- lshal
- lsmod
- lspci -vv
- cat /proc/scsi/scsi > proc.scsi.scsi
- cat /proc/modules > proc.modules
- uname -a > uname

Also, below there are detailed information about devices and OS
config/log files.

===== System info:
Operating System: Redhat Enterprise Linux AS 5(the same thing happened
using CentOS 5.2)
Sever System: HP ML530 G4
SCSI Adapter: LSI 1030

*Note that, no other SCSI devices are connected to the cable.
