Para meus dispositivos de fita SAS e SCSI, normalmente vejo os seguintes módulos carregados quando uso os controladores MPT Fusion / LSI:

[root@Lance ~]# lsmod  | grep mpt
mptctl                 31976  4 
mptspi                 17051  0 
mptscsih               36828  1 mptspi
mptbase                94037  3 mptctl,mptspi,mptscsih
scsi_transport_spi     26151  1 mptspi

Ou ...

[root@Doper ~]# lsmod  | grep mpt
mptctl                 74953  4 
mptscsih                2625  0 
mptsas                 26977  1 mptscsih
mptspi                 13521  1 mptscsih
mptscsi                50641  2 mptsas,mptspi
mptbase                78625  4 mptctl,mptsas,mptspi,mptscsi
scsi_mod              146193  9 sg,st,libata,cciss,mptsas,mptspi,mptscsi,usb_storage,sd_mod

Veja sua configuração e veja se você tem o mesmo conjunto de módulos carregado.
