Based on kernel version 3.16. Page generated on 2014-08-06 21:36 EST.

1	This driver is for Compaq's SMART2 Intelligent Disk Array Controllers.
2	
3	Supported Cards:
4	----------------
5	
6	This driver is known to work with the following cards:
7	
8		* SMART (EISA)
9		* SMART-2/E (EISA)
10		* SMART-2/P
11		* SMART-2DH
12		* SMART-2SL
13		* SMART-221
14		* SMART-3100ES
15		* SMART-3200
16		* Integrated Smart Array Controller
17		* SA 4200
18		* SA 4250ES
19		* SA 431
20		* RAID LC2 Controller
21	
22	It should also work with some really old Disk array adapters, but I am
23	unable to test against these cards:
24	
25		* IDA
26		* IDA-2
27		* IAES
28

30	EISA Controllers:
31	-----------------
32	
33	If you want to use an EISA controller you'll have to supply some
34	modprobe/lilo parameters.  If the driver is compiled into the kernel, must
35	give it the controller's IO port address at boot time (it is not
36	necessary to specify the IRQ).  For example, if you had two SMART-2/E
37	controllers, in EISA slots 1 and 2 you'd give it a boot argument like
38	this:
39	
40		smart2=0x1000,0x2000
41	
42	If you were loading the driver as a module, you'd give load it like this:
43	
44		modprobe cpqarray eisa=0x1000,0x2000
45	
46	You can use EISA and PCI adapters at the same time.

49	Device Naming:
50	--------------
51	
52	You need some entries in /dev for the ida device.  MAKEDEV in the /dev
53	directory can make device nodes for you automatically.  The device setup is
54	as follows:
55	
56	Major numbers:
57		72	ida0
58		73	ida1
59		74	ida2
60		75	ida3
61		76	ida4
62		77	ida5
63		78	ida6
64		79	ida7
65	
66	Minor numbers:
67	        b7 b6 b5 b4 b3 b2 b1 b0
68	        |----+----| |----+----|
69	             |           |
70	             |           +-------- Partition ID (0=wholedev, 1-15 partition)
71	             |
72	             +-------------------- Logical Volume number
73	
74	The device naming scheme is:
75	/dev/ida/c0d0		Controller 0, disk 0, whole device
76	/dev/ida/c0d0p1		Controller 0, disk 0, partition 1
77	/dev/ida/c0d0p2		Controller 0, disk 0, partition 2
78	/dev/ida/c0d0p3		Controller 0, disk 0, partition 3
79	
80	/dev/ida/c1d1		Controller 1, disk 1, whole device
81	/dev/ida/c1d1p1		Controller 1, disk 1, partition 1
82	/dev/ida/c1d1p2		Controller 1, disk 1, partition 2
83	/dev/ida/c1d1p3		Controller 1, disk 1, partition 3
84
