install 3ware raid card in rhel 3es
Mount the card, in my particular instance I had to worry about getting a half slot card. After that was done I read the docs for the second time and found that in order to make the drivers work I would need to compile the module 3ware doesn't certify my version of RHEL likely for cost reasons. The module source is available on the 3ware web site. I donloaded the module source and unpacked it. I then copied the makerile.rh to makefile. I changed the symbolic link for /usr/src/linux-2.4 to the correct version of the kernel, after which I was able to type "make" in the 3ware driver directory and everything went lovely.
The driver is the 3w-9xxx.o that is resulting cp this file to the /lib/modules/
run /sbin/depmod -a
partition the drives
put the correct alias into /etc/modules.conf
reboot and you should be all to the good
