Hi, it seems that your storage system announces itself as scsi-2 which has a maximum number of 7 luns/target. If your storage system announces itself as scsi-3 more luns are scanned. your kernel parameters cannot work, because they don't apply to scsi_mod. Using scsi_mod is correct. Please have a look at /usr/src/linux/Documentation/kernel-paramters.txt. There you can find more options. Do you have ghost devices or missing luns? This parameter may help scsi_allow_ghost_devices.
