In my current experimentation, I have two RAID0 arrays (4 disk total) on a
highpoint controller ("HPT370A" is printed on the chip, lspci returns
HPT366 rev 04) onboard an Abit KG7-RAID motherboard. I think I have
things set up correctly, as I have been playing with this highpoint thing
for weeks.
My problem is that Linux only recognises array #0. Interesting enough, I
can boot off the MBR of either array by changing the "BOOT" flag in
highpoint BIOS. [I have had other booting problems with this "BOOT" flag,
but am not going to go into them in this post.]
Current system setup:
--------------------
* Linux kernel version: 2.4.18-pre3-ac2 or 2.4.17
* dev-3.2-6 device files
* Just updated to latest motherboard bios, with the latest stable
highpoint bios (v2.3) from http://www.biosmods.com. Most experimentation
was done with v1.11.0402.
Lilo sees both disk arrays...
`lilo -T geom`
--------------------
BIOS reports 2 drives
bios=0x80, cylinders=1024, heads=255, sectors=63
EDD packet calls allowed
bios=0x81, cylinders=1024, heads=255, sectors=63
EDD packet calls allowed
Even though it gets the geometry incorrect...
(bug report sent)
`fdisk -l /dev/ataraid/d0`
--------------------
Disk /dev/ataraid/d0: 255 heads, 63 sectors, 10011 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System

But the Highpoint Softwareraid driver only sees one array!
...from dmesg
--------------------
Partition check:
hda: [PTBL] [5005/255/63] hda1 hda2 hda3 hda4

Highpoint HPT370 Softwareraid driver for linux version 0.01
Drive 0 is 39266 Mb
Drive 1 is 39266 Mb
Raid array consists of 2 drives.
... Only two disks? What happened to the other array!!
I read somewhere that Arjan's driver supports multiple volumes. What can
I do to get it to look for a second array?
Any help would be greatly apprecated.
