CISS(4)                   OpenBSD Programmer's Manual                  CISS(4)

NAME
     ciss - Compaq Smart ARRAY 5/6 SAS/SATA/SCSI RAID controller

SYNOPSIS
     ciss* at pci?
     scsibus* at ciss?

DESCRIPTION
     The ciss driver provides support for the Compaq Smart ARRAY 5th and 6th
     family of RAID controllers, including:

           o       Compaq 532, 5300, 5312, 5i
           o       Compaq 641, 642, 6400, 6400EM, 6422
           o       Hewlett-Packard 6i, E200, E200i, E500, P212, P400, P400i,
                   P410, P410i, P411, P600, P700m, P711m, P712m, P800, P812,
                   V100

     These controllers support RAID 0, RAID 1, RAID 5, JBOD, and superposi-
     tions 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) vari-
     able hw.sensors.

HISTORY
     The ciss driver first appeared in OpenBSD 3.8.

AUTHORS
     The ciss driver was written by Michael Shalayeff <mickey@openbsd.org>.

CAVEATS
     For purposes of status monitoring, the current code only supports one
     logical volume per controller.
