-
Compaq 641, 642, 6400, 6400EM, 6422
-
Hewlett-Packard 6i, E200, E200i, E500, H240, H240ar, H240tr, H241, H244br, P212, P220i, P222, P224br, P230i, P240tr, P246br, P400, P400i, P410, P410i, P411, P420, P420i, P421, P430, P430i, P431, P440, P440ar, P441, P530, P531, P542t, P600, P700m, P711m, P712m, P721m, P731m, P741m, P800, P812, P822, P830, P830i, P840, P841, V100
These controllers support RAID 0, RAID 1, RAID 5, JBOD, and superpositions of those configurations.
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.
Caveats
For purposes of status monitoring, the current code only supports one logical volume per controller.
