redhat 6.2 detect DD890 drivers issue

I create 50 drivers, half drivers map to active 1a  passive 1b, others map to 1b active passive 1a.

Now redhat can't auto detect drivers which mapped to host2, I have to manualy add drivers via this command.

echo "scsi add-single-device 2 0 1 #" > /proc/scsi/scsi "#" is (2,4,6,8...50)

Quesion: how to resolve the problem, server can auto detect all drivers

zone:

host1----1a

host2----1b

HBA card :emulex driver 8.3.5.45.4p
