raid support for abit VP6?

Post by Jan Vandesompel » Mon, 29 Jan 2001 01:13:22



Does anyone know how I can get my linux distro to work with my Hotrod
UDMA/raid controller? I can't install the Redhat 7.0 distro because the
install program says it cannot find any partitions to install on. Mandrake
7.2 is installed right now, but my partitions are not recognized correctly
during the installatioin process. I have managed however to install the
disto on my pc. I can only boot from a floppy however. I tried installing
lilo but that didn't work. I executed /etc/lilo, and got no error messages.
He added al the options normally. When i rebooted however, all i get is "LI"
instead of "LILO".
My setup consists of a Abit VP6 mobo, with integrated HotRod IDE UDMA/ raid
controller. I have two disks of 14,3 Gb configured in raid 1. My disks
appear as "/dev/hde" and "/dev/hdg" under linux fdisk. This is ok I guess.
There are no drives attached to my normal IDE connectors so hda,hdb,hdc,hdd
are not used. My drives are connected to the raid controller, on a different
connector, so both as master drives. So, hde and hdg seem ok to me. I have
created a linux partition of 4Gb at the beginning of my drives, plus one
swap partition of 250Mb.
Do i have to recompile my kernel for RAID support or something? I have to
recompile anyway, because my kernel is not compiled for my dual cpu setup
anyway.

Any suggestions?

raid support for abit VP6?

I'm in the same boat.  I just put together a VP6, Dual 933 Mhz PIII's, 1
Gb RAM, 2 30 Gb IBM ATA100's, etc.

I first tried to get RAID working by switching the drives to PIO mode.  
This was suggested on the RH list.  Still nothing.

I then gave up on RAID/ATA100, since I know the support is in the 2.4
kernel.  BTW, RH 7.1 (w/ 2.4 kernel) is shipping next week.  And I moved
the drives to the regular IDE channel (1). RH installs fine, however the
system does not boot, saying it can't find a device.  Upon further
investigation, I noticed that while the drives show up when you go into
the BIOS setup as the master and slave on the Primary IDE, they don't show
up when the system boots normally.  On the first screen (where you can hit
DEL to get to BIOS setup) you're supposed to see some drive info.  I get
nada.  Also when the second screen with the system summary comes up
nothing shows up on the info for the primary/seconday master/slave info.  
They all say "None" despite the fact that the RH install DOES now find the
drives as well as the IDE CD. As we speak I am reconfiguring the system to
use a boot disk.  I'm going to redo the whole thing when 7.1 is released.
Hopefully, the ATA100+RAID will work then.

1. Deadlock problem apparently solved with a ICP GDT RAID controller on a ABit VP6 motherboard.

Hi,

    Just thought I'd mention it in case anyone else has encountered the same
problem I had been having with this combination.  I reported this a couple
of months ago.  After lots of trial and error I finally found that using the
pirq="" kernel option to specify the PCI irqs apparently fixes the deadlock
problem I was having.  Once I set this parameter the RAID is able to survive
a good number of stress tests.  Funny thing is that it doesn't matter much
how I configure the pirq option.  Setting this to pretty much anything and
in any order just makes the system work.  This is despite what the
documentation on pirq says in that you have to specify exactly what the
motherboard assigns to the pci slots, usually found with trial an error.
One weird thing though.  The USB irq and possibly others are consistently
remapped by the kernel on bootup anyway despite the pirq assignments and
this trick still seams to work.  I've attached the dmesg on this system in
case anyone wants to take a look into this weirdness.
