	   -   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) command 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.

HISTORY
     The arcmsr driver first appeared in NetBSD 5.0.

AUTHORS
     The arcmsr driver was originally written for OpenBSD by David Gwynne.  It was ported to
     NetBSD and extended by Juan Romero Pardines.
