NAME

arcmsr -- Areca RAID Controller driver

SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file: device pci device scbus device da device arcmsr Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): arcmsr_load="YES"

DESCRIPTION

The arcmsr 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 accelera- tion 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 /dev/da? device nodes. A management interface is also present via the /dev/arcmsr? device node. Management tools for i386 and amd64 are available from Areca.

LOADER TUNABLES

hw.arcmsr.msi.enable By default, the driver will use MSI if it is supported. This behavior can be turned off by setting this tunable to 0.

BUGS

The driver has been tested on i386 and amd64. It likely requires addi- tional work to function on big-endian architectures. DragonFly 3.9 February 25, 2014 DragonFly 3.9
