 9.Nm ida
10.Nd Compaq Intelligent Drive Array Controllers
11.Sh SYNOPSIS
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
19.Pp
20Alternatively, to load the driver as a
21module at boot time, place the following line in
22.Xr loader.conf 5 :
23.Bd -literal -offset indent
24ida_load="YES"
25.Ed
26.Sh DESCRIPTION
27The Compaq Intelligent Drive Array (IDA) technology is used to
28distribute data across an array of hard drives.
29It unites these hard drives into one or more high-performance logical drives.
30The drive array is managed by an array controller.
31.Pp
32These controllers have the ability to provide fault tolerance for the connected
33drives and optionally provide write cache for the logical drives.
34It is also possible for an application to access the SCSI bus subsystem
35directly by using the pass-through interface.
36.Sh HARDWARE

65.Sh IMPLEMENTATION NOTES
66Extreme caution should be exercised when using the pass-through interface.
67It is possible to interfere with normal system I/O and cause hangs if
68pass-through is used to an active device.
69Pass-through should only be used to a device that is otherwise quiescent.
