This is an interface that uses the cciss passthrough to talk to the SMART controller on
the HP system. The cciss driver provides a way to send SCSI cmds through the CCISS passthrough
essentially the methods above and below pertain to SCSI, except for the SG driver which is not
involved. The CCISS driver does not engage the scsi subsystem. */
