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
52 and access to JBOD disks is provided via
55 A simple management interface is also provided on a per-controller basis via
62 name is derived from the phrase "MegaRAID Firmware Interface", which is
63 substantially different than the old "MegaRAID" interface and thus requires
65 Older SCSI and SATA MegaRAID cards are supported by
67 and will not work with this driver.
69 3 Gb/s and 6 Gb/s support both initiator target (IT) and integrated RAID (IR)
71 .Pa http://kb.lsi.com/KnowledgebaseArticle16266.aspx ) .
74 driver supports controllers with an IR image.
75 At least some cards (such as the
76 .Tn IBM ServeRAID M1015 )
79 driver when IT firmware is used.
81 Two sysctls are provided to tune the
83 driver's behavior when a request is made to remove a mounted volume.
84 By default the driver will disallow any requests to remove a mounted volume.
86 .Va dev.mfi.%d.delete_busy_volumes
88 then the driver will allow mounted volumes to be removed.
90 .Bl -tag -width indent
91 .It Va hw.mfi.msi.enable
92 By default, the driver will use MSI if it is supported.
93 This behavior can be turned off by setting this tunable to 0.
98 driver supports the following hardware:
