Array 2/3/4 SCSI RAID controller
cac* at pci?
cac* at eisa?
The cac
driver provides support for the
following RAID controllers:
All the RAID set volume management is done via the card BIOS.
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.
Monitoring status for the volume and drives in it is done through the bioctl(8) utility; the current status is provided by the sysctl(8) variable hw.sensors.
