IDA(4) Kernel Interfaces Manual IDA(4) NAME ida -- Compaq Intelligent Drive Array Controllers SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: device scbus device ida Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): ida_load="YES" DESCRIPTION The Compaq Intelligent Drive Array (IDA) technology is used to distribute data across an array of hard drives. It unites these hard drives into one or more high-performance logical drives. The drive array is managed by an array controller. These controllers have the ability to provide fault tolerance for the con- nected drives and optionally provide write cache for the logical drives. It is also possible for an application to access the SCSI bus subsystem di- rectly by using the pass-through interface. HARDWARE The following controllers are supported by the ida driver: * Compaq SMART Array 221 * Compaq Integrated SMART Array Controller * Compaq SMART Array 4200 * Compaq SMART Array 4250ES * Compaq SMART 3200 Controller * Compaq SMART 3100ES Controller * Compaq SMART-2/DH Controller * Compaq SMART-2/SL Controller * Compaq SMART-2/P Controller IMPLEMENTATION NOTES Extreme caution should be exercised when using the pass-through interface. It is possible to interfere with normal system I/O and cause hangs if pass- through is used to an active device. Pass-through should only be used to a device that is otherwise quiescent.
