    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 
   29 Installing:
   30 -----------
   31 
   32 You need to build a new kernel to use this device, even if you want to
   33 use a loadable module.  
   34 
   35 Apply the patch to a 2.2.x kernel:
   36 
   37 # cd linux
   38 # patch -p1 <smart2.patch
   39 
   40 Then build a new kernel and turn on Compaq SMART2 Disk Array support.
   41 Create device nodes for the diskarray device:
   42 
   43 # mkdev.ida [ctlrs]
   44 
   45 Where ctlrs is the number of controllers you have (defaults to 1 if not
   46 specified).
   47 
   48 EISA Controllers:
   49 -----------------
   50 
   51 If you want to use an EISA controller you'll have to supply some
   52 insmod/lilo paramaters.  If the driver is compiled into the kernel, must
   53 give it the controller's IO port address at boot time (it is no longer
   54 necessary to specifiy the IRQ).  For example, if you had two SMART-2/E
   55 controllers, in EISA slots 1 and 2 you'd give it a boot argument like
   56 this:
   57 
   58         smart2=0x1000,0x2000
   59 
   60 If you were loading the driver as a module, you'd give load it like this:
   61 
   62         insmod cpqarray.o eisa=0x1000,0x2000
   63 
   64 You can use EISA and PCI adapters at the same time.
   65 
   66 Booting:
   67 --------
   68 
   69 You'll need to use a modified lilo if you want to boot from a disk array.
   70 Its simply a version of lilo with some code added to tell it how to
   71 understand Compaq diskarray devices.
   72 
   73 Device Naming:
   74 --------------
   75 
   76 You need some entries in /dev for the ida device.  The mkdev.ida script
   77 can make device nodes for you automatically.  Currently the device setup
   78 is as follows:
   79 
   80 Major numbers:
   81         72      ida0
   82         73      ida1
   83         74      ida2
   84         etc...
   85 
   86 Minor numbers:
   87         b7 b6 b5 b4 b3 b2 b1 b0
   88         |----+----| |----+----|
   89              |           |
   90              |           +-------- Partition ID (0=wholedev, 1-15 partition)
   91              |
   92              +-------------------- Logical Volume number
   93 
   94 The suggested device naming scheme is:
   95 /dev/ida/c0d0           Controller 0, disk 0, whole device
   96 /dev/ida/c0d0p1         Controller 0, disk 0, partition 1
   97 /dev/ida/c0d0p2         Controller 0, disk 0, partition 2
   98 /dev/ida/c0d0p3         Controller 0, disk 0, partition 3
   99 
  100 /dev/ida/c1d1           Controller 1, disk 1, whole device
  101 /dev/ida/c1d1p1         Controller 1, disk 1, partition 1
  102 /dev/ida/c1d1p2         Controller 1, disk 1, partition 2
  103 /dev/ida/c1d1p3         Controller 1, disk 1, partition 3
