Hi Richard,

I have successfully installed ITSM 5.2 on a (somewhat) similar setup.
A SUSE Linux ES 8 x86 server and a STK L40 with 2 IBM LTO drives. The 
drives were actually SCSI
drives connected to a SAN router in the L40 and then connected (via a 
Brocade SAN switch) to the
server with a Qlogic  2310 HBA.

- SuSE Linux ES 8 x86
- Linux kernel 2.4.19-64gb-smp-233
- TSM 5.2.1.2
- IBM Tape driver 1.3.5
- IBM tape drive firmware 27Q1 (I know, ancient =)
- Qlogic driver for Linux 6.06.10 (actually, I think IBM recommended the 
6.05.00b9)
- Qlogic firmware 3.02.16

short walkthrough of installation:

(I'm skipping the TSM device drivers here since you only have IBM 
hardware.)

* Install and load IBM SCSI module for IBM hardware.
    # rpm -Uvh IBMtape-1.3.5.i386.rpm.bin
    # modprobe IBMtape
    # /usr/sbin/IBMtaped

* Load IBM tapeutil
    # tar xvf IBMtapeutil.1.1.6.i386.tar.bin
    # cd IBMtapeutil.1.1.6.i386 && ./IBMtapeconfig

* Check to see if drives are working

    # ls -l /dev/tsmscsi/               # This might only be for
    # ls -l /dev/st[0-9]
    # ls -l /dev/IBMtape*
    # tapeinfo -f /dev/sg3              # sg3 = library (also do this for 
your drives)
    # scsiinfo -i /dev/sg3
    # scsiinfo -i /dev/IBMtape[0-9]
    # loaderinfo -f /dev/sg3
    # mtst -f /dev/(IBMtape|tsmscsi/st) status
    # mtx -f /dev/sg3 load 1 0  # Mount from slot1 to drive0
    # mtx -f /dev/sg3 unload 1 0        # Dismount from drive0 to slot1
    # IBMtapeutil

That should basically be it.

Do the drives show up in /proc/scsi/scsi and in /proc/scsi/cat 
sg/device_strs?
Do the drives show up as generic scsi devices? (/dev/sg([0-9])
>From what I remember IBMtaped reports if it successfully finds any
IBM drives or libraries and is very verbose when creating the devices.
