Hi Mike

Could you show the output of cat /proc/scsi/scsi?
I think that it can recognize only the drive of LUN number 0.

1. Add the following line to/etc/modprobe.conf.
    options scsi_mod.o max_scsi_luns=255

2. Next, this setting must be read when you boot OS.
    #mkinitrd /boot/< your initrd image > `uname -r`
