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: Major numbers: 72 ida0 73 ida1 74 ida2 75 ida3 76 ida4 77 ida5 78 ida6 79 ida7 Minor numbers: b7 b6 b5 b4 b3 b2 b1 b0 |----+----| |----+----| | | | +-------- Partition ID (0=wholedev, 1-15 partition) | +-------------------- Logical Volume number The device naming scheme is: /dev/ida/c0d0 Controller 0, disk 0, whole device /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 /dev/ida/c1d1p3 Controller 1, disk 1, partition 3 Changelog: ========== 10-28-2004 : General cleanup, syntax fixes for in-kernel driver version.
