You may have a problem like I did this weekend:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=110653
The Fedora/Red Hat kernels don't have multi-LUN support (basically one
device with multiple disks). You can manually add the LUNs in /proc:
echo "scsi-add-single-device 0 0 0 1" > /proc/scsi/scsi
echo "scsi-add-single-device 0 0 0 2" > /proc/scsi/scsi
echo "scsi-add-single-device 0 0 0 3" > /proc/scsi/scsi
See if that helps.
