Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
mfi_load="YES"
The mfi name is derived from the phrase "MegaRAID Firmware Interface", which is substantially different than the old "MegaRAID" interface and thus requires a new driver. Older SCSI and SATA MegaRAID cards are supported by amr(4) and will not work with this driver.
Two sysctls are provided to tune the mfi driver's behavior when a request is made to remove a mounted volume. By default the driver will disallow any requests to remove a mounted volume. If the sysctl dev.mfi.%d.delete_busy_volumes is set to 1, then the driver will allow mounted volumes to be removed.
A tunable is provided to adjust the mfi driver's behaviour when attaching to a card. By default the driver will attach to all known cards with high probe priority. If the tunable hw.mfi.mrsas_enable is set to 1, then the driver will reduce its probe priority to allow mrsas to attach to the card instead of mfi.
mfi does not provide ATA TRIM support. Refer to mrsas if TRIM support is required.
