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.
