.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.
|
2006-03-29 20:53:42 +00:00
|
|
|
Older SCSI and SATA MegaRAID cards are supported by
|
|
|
|
|
.Xr amr 4
|
|
|
|
|
and will not work with this driver.
