Greetings,
I have a Promise TX2300 (latest BIOS 2.5.0.3122) that I'm trying to
use with 6.2R. I set up a two disk mirror using the card's BIOS
utility, but when I go to install FBSD my disk selection is only ad4
and ad6, the array is not being recognized (I believe I should have
an ar0 in the list as well).
I can install on a single disk just fine, I just can't get FBSD to
see the array. Any insight would be greatly appreciated.
Thanks,
Matthew

Hello Matthew!
You can read my experience with the TX4310 controller (same as
TX2300 but with 4 ports and RAID5 support - TX4300 doesn't have RAID5):

I hope you will get it work with the 'atacontrol' command:
http://www.freebsd.org/cgi/man.cgi?query=atacontrol&apropos=0&sektion=0&manpath=FreeBSD+6.2-RELEASE&format=html
The problem for me with atacontrol was that after booting Windows my
/dev/arX device always has been destroyed.
My solution was:
Buying a 3ware 8006-2LP 2-port SATA HARDWARE RAID Controller which
has better performance than the TX4310 although it's SATA and not
SATA-II and also very good Linux support.
Regards and Good Luck!

Lukas,
Thanks for the info, I'll give atacontrol a try. I never used it,
and really didn't know such a utility existed. Does it actually
write something to the disks that lets the array be recognized by
FreeBSD? I'm assuming I would:
1. Set the array in the TX2300 BIOS.
2. Boot with live file system disk and use atacontrol to make the array.
3. Reboot with install disk and install on ar0.
Is think correct or am I missing part of the picture. Also, once the
array is built, can I still use dedicated partitions, or do I have to
use compatible partitions? I can only assume that atacontrol has to
write something to the disks themselves?
Thanks,
Matthew

Hi Matthew!
Yes, that's right but it's important how you use atacontrol...
Your stripe size will be 16kB i think (see TX2300 BIOS settings), so
you have to set 32 in atacontrol (because 32 * 512B = 16kB).
To add your adX and adY device you could enter:
atacontrol create RAID0 32 adX adY
or
atacontrol create RAID0 32 adY adX
The order is important!
You can figure the right order out by:
1. Setting the array in the TX2300 BIOS
2. Running Linux with the right module or
Windows Installation CD (with the TX2300 drivers from floppy disk)
3. Partitioning the "RAID device"
You needn't install any of these Operating Systems...
4. Restart the system and...
then you can run FreeBSD from an Installation CD and try to create an
arZ device by using atacontrol.
If you restart the system and see the new arZ device during the
installation, so you've entered the devices in the right order.
otherwise you should delete the arZ device by atacontrol and create a
new one with passing the ad devices in another order.
If you've more questions then ask... :-)
Good luck and best regards!
Lukas

Hey Lukas,
Thanks for the response! Wow, that seems like a messy procedure, but
I'll go see if I can get things working. I only have three questions at
this point:
1. What is atacontrol doing that lets FreeBSD see the array?
2. After using atacontrol, is this now a software or hardware array?
3. Is there anyone I can send my card to who can fix FreeBSD?
It seems this card used to work, and after a BIOS update from Promise,
FreeBSD support broke. I'd be glad to loan my card to whoever can fix
the driver or whatever it takes.
Thanks,
Matthew
