RocketRAID (rr622x) PCI-e 6gbp card How-to

[Cluster_1]

Okay I found a simple how-to that can help people who have a rocketraid 622/644 pci-e card. These instructions were taken from ubuntu's page (I know..) But seriously I worked with them tonight and these instructions worked for me without giving me a problem. I know I posted for help before but I found something and I made it work and I figure I would share the knowledge

I am posting a link to these instructions as I do not want to take credit for someone else's work.

https://help.ubuntu.com/community/RocketRaid

Everything worked as explained these instructions worked for Fedora 15 only, I did not test them in 16.

If people would like I can write them out but again someone else figured this out and I wanted to share!

Enjoy!

The driver for this card does not work on the latest kernel. The attached patch is against the latest source available from HighPoint:
rr62x-linux-src-v1.2-120601-1355.tar.gz

It accounts for a kernel change in kmap_atomic() and kunmap_atomic(), and sends a correct reply for requests with an invalid command opcode. The latter change is necessary in the newest kernels to avoid getting a flood of kernel messages "WRITE SAME failed. Manually zeroing."

Additionally, I had to set the BIOS to initialize add-in cards first due to a known conflict between this card and onboard RAID controllers.

This is definitely an economy card, but it seems to be working welll with good performance. I hope this helps someone lese trying to get this card working.
