Hi,
i recently bought a new server with an Intel ICH7 chipset and embedded
LSI Raid.
I set the SATA mode in the BIOS to RAID. After that, i was able to
configure a RAID1 array using the Controllers BIOS.
Unfortunately, FreeBSD isn't seeing any of the installed HDs.
I tried to change the BIOS settings for SATA in the BIOS to all available
methods (RIAD, AHCI, NATIVE) with no success.
The only setting that makes FreeBSD able to see the HDs is COMPATIBLE, but
i loose the PATA channel if i use it, which is definitely not what i
want.
I tried the above with 6.0-RELEASE and RELENG_6 from "Thu Feb 2 18:32:06
CET 2006".
I took a closer look into the RELENG_6 ata(4) code and found the following
line in ata-chipset.c :
{ ATA_I82801GB_R1, 0, AHCI, 0x00, ATA_SA300, "ICH7" }
After i changed this line to :
{ ATA_I82801GB_R1, 0, 0, 0x00, ATA_SA300, "ICH7" }
i was able to detect the two HDs AND the configured RAID1 array. I could
use fdisk(8) and bsdlabel(8) to set up the disk and can finally use it.
Unfortunately, i can only use two disk, as all other channels do NOT
appaer in FreeBSD, i think this is related to my change in the source, as
previously all channels where available, but without HDs.
I would really like to use the other channels too.
One problem could be the "RAID or AHCI enabled - detection code" in
ata_chipset.c (rev 1.126.2.8 in RELENG_6) below line 1660, but i'm not
sure.
Is there any chance we can track this down to make it working in a general
way, without the need to change the sources everytime i've cvsupped my
source tree?
I'm glad to help wherever i can to solve this issue.
regards
Joerg
