Getting IDE drivers to work on a RAID controller PCI card
in [General Linux]
|
From: James H. Newman on 25 Jul 2008 20:36 A PC has come my way with a motherboard with a single IDE controller, plus a PCI IDE RAID controller PCI card. The boot drive and another hard drive are connected to the IDE controller, whereas the DVD writer and yet another hard drive are connected to the RAID controller. My current Linux kernel is unable to detect the DVD writer and the third hard drive. I assume that I must build a kernel containing RAID support. Is that all there is to it? I mean, do I have to know any specifics about the RAID controller itself, or will Linux recognize it no matter what, just as it recognizes IDE hard drives? Must one tackle any configuration other than the usual stuff for IDE drives? I have done a google search and found some pointers, but since I know nothing about RAID controllers I find them a bit confusing. Some idiot-proof pointers would be welcome. By the way, I would like this to work under Slackware 12.

If you know the make+model of the PCI card, you will know which module you have to modprobe. "lspci" will help out a great deal here. Like so: mallory:~$ lspci | grep IDE 00:06.0 IDE : nVidia Corporation CK804 IDE (rev f2) 00:07.0 IDE : nVidia Corporation CK804 Serial ATA Controller (rev f3) 00:08.0 IDE : nVidia Corporation CK804 Serial ATA Controller (rev f3) ....obviously, I have a CK804 here, which is supported by the sata_nv module according to a grep -rli ck804 /usr/src/linux/drivers/ . > or will Linux recognize it no matter what, just as it recognizes IDE > hard drives? You'll have to do something similar to what's described above. If this controller card is treating the disk as a "RAID set" or something like that instead of as a normal disk, the data on it might not be usable. > By the way, I would like this to work under Slackware 12. Slack users are expected to be able to handle these sorts of things. If you want more hand-holding, use something like Ubuntu instead. You should post the relevant output from lspci so that we could take a look at it.

If you install a Linux distro on this hardware, it will either automatically configure the correct module, or fail to detect your RAID card. If the latter, your RAID card is not supported by the version of the Linux kernel that ships with your Linux distribution. If you install the RAID card after you already installed Linux, it's possible that it may not get automatically recognized, even if it's supported by the Linux kernel. > I mean, do I have to know any > specifics about the RAID controller itself, or will Linux recognize it no > matter what, just as it recognizes IDE hard drives?

If you identify your RAID controller's vintage, you may be able to do some research and determine whether it is supported by the Linux kernel, and if so, in which kernel version support was added by your hardware card. > I have done a google search and found some pointers, but since I > know nothing about RAID controllers I find them a bit confusing.

Your first step is to determine whether or not your RAID card is supported at all, by the Linux kernel. The kernel supports some, but not all RAID cards. Most RAID Linux machines use Linux soft-RAID, which works with any underlying platform, IDE or SCSI. Once you determine that your RAID card should be supported by the Linux kernel, and which was the first kernel release that added support for your card, then you should be able to determine if Slackware ships the kernel that includes the drivers for your RAID card, and determine the next step.

This is what I get from lspci: 01:02.0 RAID bus controller: VIA Technologies, Inc. VT6410 ATA133 RAID controller (rev 06) My question is, how do I configure the kernel build environment to include support for this hardware?

If you're using a distro kernel, the module is already in /lib/modules/`uname -r`/ . Follow the procedure shown in the line marked with a bunch of ^s to find the name of the module you need to modprobe. You won't be looking for "ck804", of course, but for another string that's unique to this particular piece of hardware. If you have compiled a custom kernel, you need to compile the appropriate device driver, which you can find using the same command. Then just do a "make menuconfig", navigate to the right place, and set the appropriate option to "M", "make modules && make modules_install", and you're good. The fact that you're asking these questions makes me think you would be better served by a distro that does more hand-holding. -- Outside of a dog, a book is a man's best friend.
