NAME

     arcmsr -- Areca Technology Corporation SATA/SAS RAID controller


SYNOPSIS

     arcmsr* at pci? dev ? function ?


DESCRIPTION

     The arcmsr driver provides support for the PCI-X and PCI Express RAID
     controllers from Areca Technology Corporation:

           -   ARC-1110 PCI-X 4 Port SATA RAID Controller
           -   ARC-1110ML PCI-X 4 Port SATA RAID Controller
           -   ARC-1120 PCI-X 8 Port SATA RAID Controller
           -   ARC-1120ML PCI-X 8 Port SATA RAID Controller
           -   ARC-1130 PCI-X 12 Port SATA RAID Controller
           -   ARC-1130ML PCI-X 12 Port SATA RAID Controller
           -   ARC-1160 PCI-X 16 Port SATA RAID Controller
           -   ARC-1160ML PCI-X 16 Port SATA RAID Controller
           -   ARC-1170 PCI-X 24 Port SATA RAID Controller
           -   ARC-1200 Rev A PCI Express 2 Port SATA RAID Controller
           -   ARC-1202 PCI Express 2 Port SATA RAID Controller
           -   ARC-1210 PCI Express 4 Port SATA RAID Controller
           -   ARC-1220 PCI Express 8 Port SATA RAID Controller
           -   ARC-1230 PCI Express 12 Port SATA RAID Controller
           -   ARC-1230ML PCI Express 12 Port SATA RAID Controller
           -   ARC-1231ML PCI Express 12 Port SATA RAID Controller
           -   ARC-1260 PCI Express 16 Port SATA RAID Controller
           -   ARC-1260ML PCI Express 16 Port SATA RAID Controller
           -   ARC-1261ML PCI Express 16 Port SATA RAID Controller
           -   ARC-1280 PCI Express 24 Port SATA RAID Controller
           -   ARC-1280ML PCI Express 24 Port SATA RAID Controller
           -   ARC-1680 PCI Express 8 Port SAS RAID Controller
           -   ARC-1680LP PCI Express 8 Port SAS RAID Controller
           -   ARC-1680i PCI Express 8 Port SAS RAID Controller
           -   ARC-1680x PCI Express 8 Port SAS RAID Controller
           -   ARC-1681 PCI-X 8 Port SAS RAID Controller

     These controllers support RAID levels 0, 1, 1E, 3, 5, 6, and JBOD using
     either SAS or SATA II drives.

     arcmsr supports management and monitoring of the controller through the
     bioctl(8) and envstat(8) commands.

     Please note, however, that to use some features that require special
     privileges, such as creating/removing hot-spares, pass-through disks or
     RAID volumes will require to have the password disabled in the firmware;
     otherwise a Permission denied error will be reported by bioctl(8).

     When a RAID 1 or 1+0 volume is created, either through the bioctl(8) com-
     mand or controller's firmware, the volume won't be accessible until the
     initialization is done.  A way to get access to the sd(4) device that
     corresponds to that volume without rebooting, is to issue the following
     command (once the initialization is finished):

     $ scsictl scsibus0 scan any any

     The arcmsr driver will also report to the kernel log buffer any error
     that might appear when handling firmware commands, such as used by the
     bioctl(8) command.


EVENTS

     The arcmsr driver is able to send events to powerd(8) if a volume or any
     drive connected to the volume is not online.  The state-changed event
     will be sent to the /etc/powerd/scripts/sensor_drive script when such
     condition happens.
