Abit VP6 and Hotrod 100 IDE raid controller

Abit VP6 and Hotrod 100 IDE raid controller

Post by jan vandesompel » Fri, 22 Jun 2001 23:29:28



Does anyone know if it's possible to run Linux on an Abit VP6 motherboard
with a Hotrod 100 IDE raid controller attached to it? I have two disks of
30Gb configured in a striped Raid 0 configuration. I have created a Win2k
partition (lame I know...) and I want to install linux on the raid
configuration as well. I have tried both Suse 7.1 and Mandrake 8.0 but they
don't recognize my Raid 0 config. I have read that it is possible to install
linux on a disk attached on the raidcontroller (not configured in Raid
however, you look at it as a regular single disk), but that's not what I
want. I want linux running on Raid 0. Is this possible?

Abit VP6 and Hotrod 100 IDE raid controller

Currently, the Linux kernel DOES NOT support the RAID features of the
HPT370 chipset, but highpoint-tech ( the people behind that chipset )
promised me in an email 3 month ago, that they will develop a RAID
compatible driver on their own, so all we can do is sit back and wait
...:(

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.
