Since this topic still seems alive, it is possible to manually load the driver (kext, aka kernel extention).
Mac-mini:~ promise$ kextstat | grep SAN
Mac-mini:~ promise$ cd /Library/Extensions/
Mac-mini:Extensions promise$ ls -d SAN*
Mac-mini:Extensions promise$ sudo kextload SANLink-FC.kext/
Mac-mini:Extensions promise$ kextstat | grep SAN
171 0 0xffffff7f84689000 0x8f000 0x8f000 com.promise.SANLink-FC (2.0.9) A7C7DC73-52FD-3D15-A566-3EA56E3EA535 <72 13 6 5>
The first command shows if the SanLink driver is loaded. If it returns nothing, then the driver did not load.
Tthe 'kextload' command loads the kernel extention, we need to cd to the /Library/Extentions folder and use the full name of the driver bundle. Sudo is required to load a driver.
Curiously this morning I loaded the SANLink3 driver and it would not start. The settings in the security tab were correct, so I manually loaded the driver as above.
