NAME
ciss —
Compaq Smart Array SAS/SATA/SCSI RAID
controller
SYNOPSIS
ciss* at pci?
DESCRIPTION
The ciss driver provides support for
Compaq Smart Array SAS/SATA/SCSI RAID controllers, including:
- Compaq 532, 5300, 5312, 5i
- 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.
