p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -literal -offset indent mfi_load="YES" .Ed .Sh DESCRIPTION This driver is for LSI's next generation PCI Express SAS RAID controllers. Access to RAID arrays (logical disks) from this driver is provided via
a /dev/mfid? device nodes. A simple management interface is also provided on a per-controller basis via the
p The .Nm 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 .Xr amr 4 and will not work with this driver.
p .Sh HARDWARE The .Nm driver supports the following hardware:
