| 12To compile this driver into the kernel,
13place the following lines in your
14kernel configuration file:
15.Bd -ragged -offset indent
16.Cd "device scbus"
17.Cd "device ida"
18.Ed

14.Sh DESCRIPTION
15The Compaq Intelligent Drive Array (IDA) technology is used to
16distribute data across an array of hard drives.
17It unites these hard drives into one or more high-performance logical drives.
18The drive array is managed by an array controller.
19.Pp
20These controllers have the ability to provide fault tolerance for the connected
21drives and optionally provide write cache for the logical drives.
22It is also possible for an application to access the SCSI bus subsystem
23directly by using the pass-through interface.
24.Sh HARDWARE
25The following controllers are supported by the
26.Nm

53.Sh IMPLEMENTATION NOTES
54Extreme caution should be exercised when using the pass-through interface.
55It is possible to interfere with normal system I/O and cause hangs if
56pass-through is used to an active device.
57Pass-through should only be used to a device that is otherwise quiescent.
