32 .Nd "LSI MegaRAID SAS driver"
34 To compile this driver into the kernel,
35 place the following lines in your
36 kernel configuration file:
37 .Bd -ragged -offset indent
42 Alternatively, to load the driver as a
43 module at boot time, place the following line in
45 .Bd -literal -offset indent
49 This driver is for LSI's next generation PCI Express SAS RAID controllers.
50 Access to RAID arrays (logical disks) from this driver is provided via
53 A simple management interface is also provided on a per-controller basis via
60 name is derived from the phrase "MegaRAID Firmware Interface", which is
61 substantially different than the old "MegaRAID" interface and thus requires
63 Older SCSI and SATA MegaRAID cards are supported by
65 and will not work with this driver.
67 Two sysctls are provided to tune the
69 driver's behavior when a request is made to remove a mounted volume.
70 By default the driver will disallow any requests to remove a mounted volume.
72 .Va dev.mfi.%d.delete_busy_volumes
74 then the driver will allow mounted volumes to be removed.
78 driver supports the following hardware:
82 LSI MegaRAID SAS 8408E
84 LSI MegaRAID SAS 8480E
93 .Bl -tag -width ".Pa /dev/mfid?" -compact
95 array/logical disk interface
101 .It "mfid%d: Unable to delete busy device"
102 An attempt was made to remove a mounted volume.
110 driver first appeared in
115 driver and this manual page were written by
116 .An Scott Long Aq scottl@FreeBSD.org .
118 The driver does not support big-endian architectures at this time.
