12 To compile this driver into the kernel,
13 place the following lines in your
14 kernel configuration file:
15 .Bd -ragged -offset indent
20 Alternatively, to load the driver as a
21 module at boot time, place the following line in
23 .Bd -literal -offset indent
27 The Compaq Intelligent Drive Array (IDA) technology is used to
28 distribute data across an array of hard drives.
29 It unites these hard drives into one or more high-performance logical drives.
30 The drive array is managed by an array controller.
32 These controllers have the ability to provide fault tolerance for the connected
33 drives and optionally provide write cache for the logical drives.
34 It is also possible for an application to access the SCSI bus subsystem
35 directly by using the pass-through interface.
37 The following controllers are supported by the
43 Compaq SMART Array 221
45 Compaq Integrated SMART Array Controller
47 Compaq SMART Array 4200
49 Compaq SMART Array 4250ES
51 Compaq SMART 3200 Controller
53 Compaq SMART 3100ES Controller
55 Compaq SMART-2/DH Controller
57 Compaq SMART-2/SL Controller
59 Compaq SMART-2/P Controller
61 Compaq SMART-2/E Controller
63 Compaq SMART Controller
65 .Sh IMPLEMENTATION NOTES
66 Extreme caution should be exercised when using the pass-through interface.
67 It is possible to interfere with normal system I/O and cause hangs if
68 pass-through is used to an active device.
69 Pass-through should only be used to a device that is otherwise quiescent.
