.Sh NAME
|
|
.Nm arcmsr
|
|
.Nd Areca RAID Controller driver
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device pci"
|
|
.Cd "device scbus"
|
|
.Cd "device da"
|
|
.Cd "device arcmsr"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
arcmsr_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the Areca ARC-11xx, ARC-12xx, ARC-13xx,
|
|
ARC-16xx and ARC-18xx series of SAS and SATA RAID controllers.
|
|
These controllers feature RAID-0, 1, 3, 5, 6, and 10 and
|
|
JBOD acceleration for up to 16 SATA drives.
|
|
RAID level and stripe level
|
|
migration, online capacity expansion, hot insertion/removal, automatic failover
|
|
and rebuild, and SMART are also supported.
|
|
Access to the arrays is provided
|
|
via the SCSI CAM
|
|
.Pa /dev/da?
|
|
device nodes.
|
|
A management interface is also present via the
|
|
.Pa /dev/arcmsr?
|
|
device node.
|
|
Management tools for i386 and amd64 are available from Areca.
