Mirror support on HighPoint 374?

[David Dindorp]

Hi W;

It's been a few months, but I've finally gotten the time to look at it.
I hope that you have some time to help me further with this.
(Thanks for the help so far!)

The array works just dandy except in Linux.
You were absolutely right about the signature, it has moved to the end of the disk!

I'll spare you the details of the extraordinarily clumsy way that I used to locate the signature :-),
(there's a first time for everything..), but here is the technical details:

Harddrives:
hde: 156355584 sectors (80054059008 bytes / 80054 MiB), CHS=155114/16/63, RAID0: System
hdg: 156301488 sectors (80026361856 bytes / 80026 MiB), CHS=155061/16/63, RAID1: Data
hdi: 156355584 sectors (80054059008 bytes / 80054 MiB), CHS=155114/16/63, RAID0: System
hdk: 156355584 sectors (80054059008 bytes / 80054 MiB), CHS=155114/16/63, RAID1: Data

Signatures (well, array names, really) found at:
hde: byte 5081
hdg: byte 80026356256
hdi: byte 5081
hdk: byte 80054053408

I don't know the exact starting / ending point of the signature, but the name of the array ('Data') seems to be
consistently placed at the end of the disk minus 5600 bytes.
The last 16 sectors of hdg and hdk are attached, if you'd like to have a look for yourself.

I would overly appreciate if you could guide me on what to do next to get a working Linux installation up and running,
given this new knowledge. I'm contemplating trying to install a 2.6 distro, except if 2.6 doesn't support ATARAID adapters,
it'll of course be 2.4.x.

Hope you can help :-).
Best regards

PS. The hpt374 BIOS used to create both arrays (afair!) is version 3.01.
