p These controllers support RAID 0, RAID 1, RAID 5, JBOD, and superpositions of those configurations.
p Although the controllers are actual RAID controllers, the driver makes them look just like SCSI controllers. All RAID configuration is done through the controllers' BIOSes.
p Monitoring status for the volume and drives in it is done through the .Xr bioctl 8 utility; the current status is provided by the .Xr sysctl 8 variable .Va hw.sensors . .Sh SEE ALSO .Xr bio 4 , .Xr intro 4 , .Xr pci 4 , .Xr scsi 4 , .Xr sd 4 , .Xr bioctl 8 , .Xr sensorsd 8 , .Xr sysctl 8 .Sh HISTORY The .Nm driver first appeared in .Ox 3.8 . .Sh AUTHORS The .Nm driver was written by .An Michael Shalayeff Aq Mt mickey@openbsd.org . .Sh CAVEATS For purposes of status monitoring, the current code only supports one logical volume per controller.
