.Sh NAME
.Nm mfi
.Nd "LSI MegaRAID SAS driver"
.Sh SYNOPSIS
.Cd "device pci"
.Cd "device mfi"
.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
.Pa /dev/mfid?
device nodes.
A simple management interface is also provided on a per-controller basis via
the
.Pa /dev/mfi?
device node.
.Pp
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.
