CMD Technology Inc PCI0649 (rev 2)
Well, thats what an lspci returns for my ATA MegaRaid PCI Controller. Yea I know, ancient and not supported well, but Im a sucker for Ebay.
Regardless, does anyone know how to install Gentoo on the damn thing? Ideally I would like to install Gentoo to the raid from Knoppix. I could boot from the Live CD, but I am not sure I could get the Kernel to use the raid. I have been very unsuccessful at finding a module to load. I have heard of, and seen, a megaide.o in reference to Red Hat and SUSE, but it was all kernel 2.4.
Does anyone know if it is possible to get this working under the 2.6.9 kernel in Knoppix 3.7 so I could install Gentoo to the raid. If not, and I use the Live CD, does anyone know if this hardware is supported right off the CD?
Since this machine is completely empty, I am waiting to do a complete install until 2005.0 is released. I know this is going to be using the 2.6 by default. And I would like to use the 2.6. I guess even if I can get it manually configured in the kernel for the installed Gentoo, I still need to get the raid seen initially so I can install to it.
I know of the doataraid boot option, but it doesnt seem to support megaraid/ide (whatever it is). Any ideas would be really helpful. Thanks again!

PS. I know this could be under the installation forum, but I think it is more kernel related. Sorry if I assumed incorrectly. |

if i look in the kernel config, then i see this: | Code: | Linux Kernel v2.6.11-rc5 Configuration

searching for it in the kernel sources results in: | Code: | ns2 linux-2.6.11-rc5 # find . -iname "cmd64*" -type f
./drivers/ide/pci/cmd640.c
./drivers/ide/pci/cmd64x.c
./drivers/ide/pci/cmd64x.o
./include/config/blk/dev/cmd640.h
./include/config/blk/dev/cmd64x.h
ns2 linux-2.6.11-rc5 # |
for me this means the module is called "cmd64x"
cheers

Well, we are getting closer. I ran a search for the modules as well, came up with the same results, however it was all for the 2.4 Kernel under Knoppix 3.7. Maybe I could install Gentoo 2005.0 from Knoppix running the 2.4 kernel??? I haven't tried yet, just hoping. Thanks for your help, I will let you know if it works.

you can start knoppix 3.7 with kernel 2.6 by using: knoppix26 2
this starts knoppix with kernel 2.6 in console mode

Yes...I was starting Knoppix 3.7 with:
knoppix26 doataraid
It booted the 2.6, but I am not even sure if the ataraid is a cheat code anymore or not. However, the raid still didn't come up. So, following the Steveb's reply, I attempted to load the cmd64x.o module:
insmod cmd64x.o
Course, this module is only built for the 2.4 Kernel, so I wasted my time with the initial boot options anyways, I should have just hit enter. So that is what I will do when I get home from work. Hopefully the raid will, "come right up" as a device.
I still have a lot of learning to do for Raids, especially installing on them and booting them, but I figure one fence at a time, so first thing is first and I gotta get something to see it. Thanks again for all your replies! Any other advice, tips, or tricks always appreciated.

Alright, I think I may be getting somewhere. I am not sure though if it worked or not. Would I beable to fdisk -l the device to see the geometry of the ataraid? The reason I think it may have worked is, I have in /dev ataraid, also I have /dev/initrd. What does a raid device look like, is it an hd*? What else do I have to do other then boot with, doataraid. I have been reading, but nothing is really clear. Does anyone know of a nice up to date how to for ata hardware raid with the 2.6 kernel? Thanks

[edit]
by the way, in /proc/ide i have cmd64x. when I cat it, I can see the drives hooked to the controller. |

when you do a hardware raid, then the os normaly does not know anything about that and handles the disk as if they would be normal disks. on my compaq proliant servers where i have some smart array controllers, the driver it self makes other device nodes then the normal one. but from the viewpoint of gentoo linux the disks are normal disks. gentoo does not know that i have raid on them and gentoo does not know what type of raid i run on the disks.
cheers

btw: for raid under linux (not only hw raid): http://www.faqs.org/contrib/linux-raid/
btw2: maybe you want to look into lvm2 for dynamicly handling the disk system |

I would suggest using the hardware RAID card as just additional IDE ports and using the kernel's software RAID. It's very good, and there are alot more tools available for that.
