Re: Support fot ULi (ALI or nVidia?) RAIDs

Hi Heinz,

I am bit new to efforts of RAID5 support in dmraid... Let me describe
what I have here: I have that ASUS M8R32-MVP motherboard and it has two
SATA controllers and so two SHRAID bioses. Although I am playing with
ULi ones, since it supports up to 4 drives (other one - SiL - has
support for two and one of them is external - I did not tryed it yet).

So, my config now is 3 300G disks configured as RAID5 in bios. So,
computer can boot from this shRAID5 and I managed to install Windows
there as well (although I needed to go buy floppy drive to do that,
since windows of course requires drivers on installation phase).

So, as long as I am not using those 3 hard drives for anything useful (I
am using linux on that computer from USB hard drive) - I can do any
silly things there. So far - kernel does recognizes all three HDD's as
sda, sdb and sdc, although can see partition only on one of them (that
is understandable, since RAID5 is employed there). Running dmraid -rD
(or with any other swithces gives same result - No Software RAID disks.

What else I did - pathced kernel with RAID-45 (do not remember exact
name), although hunk#9 did not succeed (I am using 2.6.17-rc1-mm2
kernel) and I have no clue what to do with it.

So, as usual - if you can provide me with instructions on what to play
there - I willingly will follow with no problem.

Regards,
Alex
