30.Sh NAME
31.Nm arcmsr
32.Nd Areca RAID Controller driver
33.Sh SYNOPSIS
34To compile this driver into the kernel,
35place the following lines in your
36kernel configuration file:
37.Bd -ragged -offset indent
38.Cd "device pci"
39.Cd "device scbus"
40.Cd "device da"
41.Cd "device arcmsr"
42.Ed
43.Pp
44Alternatively, to load the driver as a
45module at boot time, place the following line in
46.Xr loader.conf 5 :
47.Bd -literal -offset indent
48arcmsr_load="YES"
49.Ed
50.Sh DESCRIPTION
51The
52.Nm
53driver provides support for the Areca ARC-11xx, ARC-12xx, ARC-13xx,
54ARC-16xx and ARC-18xx series of SAS and SATA RAID controllers.
55These controllers feature RAID-0, 1, 3, 5, 6, and 10 and
56JBOD acceleration for up to 16 SATA drives.
57RAID level and stripe level
58migration, online capacity expansion, hot insertion/removal, automatic failover
59and rebuild, and SMART are also supported.
60Access to the arrays is provided
61via the SCSI CAM
62.Pa /dev/da?
63device nodes.
64A management interface is also present via the
65.Pa /dev/arcmsr?
66device node.
67Management tools for i386 and amd64 are available from Areca.
68.Sh LOADER TUNABLES
69.Bl -tag -width indent
70.It Va hw.arcmsr.msi.enable
71By default, the driver will use MSI if it is supported.
72This behavior can be turned off by setting this tunable to 0.

172.Sh AUTHORS
173The driver was written by
174.An Erich Chen Aq erich@areca.com.tw .
175.Sh BUGS
176The driver has been tested on i386 and amd64.
177It likely requires additional
178work to function on big-endian architectures.
