It's my understanding that the Promise controller is NOT true hardware-based
RAID. I used a 3Ware controller ($139 from NewEgg.com) that booted without
any drivers (SuSE 9.1). It appears to be a SCSI host controller to Linux,
and is a true hardware-based RAID. It allows you to mirror your swap
partition, so you don't crash if you lose one disc. With software RAID, you
will crash if you lose /swap on one drive. Not a big issue on a
workstation, but a big issue for a server.
I'm told there are performance issues with it, and software RAID is faster.
It's worked well for me, however.

Subject: [SLUG] Fastrack TX2000 IDE Raid Controller, mandrake 10, kernel
2.6.x
Hello,
After another hard drive failure, I invested in a Promise Fastrack TX2000
IDE Raid Controller, which supposedly works under Linux. Promise has
released several different versions of drivers, but none for Mandrake 10,
and I can't get any of the others to work. They've also released source
code, and I'm trying to compile for my system, but I get warnings and and an
error. I've managed to fix the warnings by making slight modifications to
some of the .c files, but I can't get rid of the
error:
*******************************************************
[root@mail fasttrack]# make clean all
rm -f FastTrak.o wrapper.o fasttrak.o ftlog.o gcc -D__KERNEL__
-I/usr/src/linux/include -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer
-fno-strict-aliasing -fno-common -pipe
-mpreferred-stack-boundary=2 -march=i586 -DMODULE -c wrapper.c
wrapper.c: In function `ft_handler_wrapper':
wrapper.c:97: error: `io_request_lock' undeclared (first use in this
function)
wrapper.c:97: error: (Each undeclared identifier is reported only once
wrapper.c:97: error: for each function it appears in.)
make: *** [wrapper.o] Error 1
*********************************************************
Here is the snippet of code that I assume is causing the error in wrapper.c:
*********************************************************
void ft_handler_wrapper(int irq, void *dev_id, struct pt_regs *regs) {
/* channel driver is system independent so it does not
need pt_regs structure */
ulong smpflag;
spin_lock_irqsave(&io_request_lock,smpflag);
ft_handler(irq, dev_id);
spin_unlock_irqrestore(&io_request_lock,smpflag);
*********************************************************
But not being a programmer, I have no idea how to fix it. Do I need to
declare io_request_lock as some kind of variable? Or is it declared in
something referenced in the #include statements?
I downloaded the source code from
http://www.promise.com/support/download/download2_eng.asp?productId=88&categ
ory=driver&os=100
There are two versions of the souce code, I've tried to compile both, with
the same results.
I've called Promise, and left a message with their tech support, but I doubt
they'll bother to call back...
Any help is greatly appreciated!
Doug
