Question about loading lpfc_scst Module

For details about how to load the lpfc_scst module-Linux general technology-Linux technology and application information, see the following. Thank you!
The younger brother is building a point-to-point Optical Fiber Channel disk array, while performing initiator and target on the other end. The target end is basically complete, an error occurred while loading lpfc_scst (I used the emulex card) in the last step. The prompt is as follows:
FATAL: Error inserting lpfc_scst (/lib/modules/2.6.18-prep/kernel/drivers/scsi/lpfc_scst/lpfc_scst.ko): Unknown symbol in module, or unknown parameter (see dmesg)
