This driver is for Compaq's SMART2 Intelligent Disk Array Controllers.
|
||
|
|
|
||
|
|
Supported Cards:
|
||
|
|
----------------
|
||
|
|
|
||
|
|
This driver is known to work with the following cards:
|
||
|
|
|
||
|
|
* SMART (EISA)
|
||
|
|
* SMART-2/E (EISA)
|
||
|
|
* SMART-2/P
|
||
|
|
* SMART-2DH
|
||
|
|
* SMART-2SL
|
||
|
|
* SMART-221
|
||
|
|
* SMART-3100ES
|
||
|
|
* SMART-3200
|
||
|
|
* Integrated Smart Array Controller
|
||
|
|
* SA 4200
|
||
|
|
* SA 4250ES
|
||
|
|
* SA 431
|
||
|
|
* RAID LC2 Controller
|
||
|
|
|
||
|
|
It should also work with some really old Disk array adapters, but I am
|
||
|
|
unable to test against these cards:
|
||
|
|
|
||
|
|
* IDA
|
||
|
|
* IDA-2
|
||
|
|
* IAES
|
||
|
|
|

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

Device Naming:
|
||
|
|
--------------
|
||
|
|
|
||
|
|
You need some entries in /dev for the ida device. MAKEDEV in the /dev
|
||
|
|
directory can make device nodes for you automatically. The device setup is
|
||
|
|
as follows:
|
||
|
|
|
||
|

|
||
|
|
|

The device naming scheme is:
|

|
||
|
|
/dev/ida/c0d0p1 Controller 0, disk 0, partition 1
|
||
|
|
/dev/ida/c0d0p2 Controller 0, disk 0, partition 2
|
||
|
|
/dev/ida/c0d0p3 Controller 0, disk 0, partition 3
|
||
|
|
|
||
|
|
/dev/ida/c1d1 Controller 1, disk 1, whole device
|
||
|
|
/dev/ida/c1d1p1 Controller 1, disk 1, partition 1
|
||
|
|
/dev/ida/c1d1p2 Controller 1, disk 1, partition 2
|
