1 This driver is for Compaq's SMART2 Intelligent Disk Array Controllers.
6 This driver is known to work with the following cards:
16 * Integrated Smart Array Controller
21 It should also work with some really old Disk array adapters, but I am
22 unable to test against these cards:
31 You need to build a new kernel to use this device, even if you want to
32 use a loadable module.
34 Apply the patch to a 2.2.x kernel:
37 # patch -p1 <smart2.patch
39 Then build a new kernel and turn on Compaq SMART2 Disk Array support.
40 Create device nodes for the diskarray device:
44 Where ctlrs is the number of controllers you have (defaults to 1 if not
50 If you want to use an EISA controller you'll have to supply some
51 insmod/lilo paramaters. If the driver is compiled into the kernel, must
52 give it the controller's IO port address at boot time (it is no longer
53 necessary to specifiy the IRQ). For example, if you had two SMART-2/E
54 controllers, in EISA slots 1 and 2 you'd give it a boot argument like
59 If you were loading the driver as a module, you'd give load it like this:
61 insmod cpqarray.o eisa=0x1000,0x2000
63 You can use EISA and PCI adapters at the same time.
68 You'll need to use a modified lilo if you want to boot from a disk array.
69 Its simply a version of lilo with some code added to tell it how to
70 understand Compaq diskarray devices.
75 You need some entries in /dev for the ida device. The mkdev.ida script
76 can make device nodes for you automatically. Currently the device setup
