From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.8) Gecko/20061025 Firefox/1.5.0.8 Description of problem: The latest version of 3w-9xxx.c, from manufacturer 2.26.06.001, is supposed to support the 9650SE card. It is designed for newer than 2.6.9 kernels and will not compile on RHEL 4. I need to deploy a production server and don't want to buy an older controller as a work around. Version-Release number of selected component (if applicable): 2.26.04.010 How reproducible: Always Steps to Reproduce: 1. Installer won't recognize drives. Actual Results: Expected Results: Additional info: Upstream maintainer: Tom Couch <linuxraid@amcc.com>
I got the install accomplished using version 2.26.05.006 of the 3w-9xxx kernel module I found on www.3ware.com. It looks like they have tested it with WS. I used it successfully with ES. It appears that the 2.26.05 series of 3w-9xxx is dedicated to kernel 2.6.9. 3ware's site also contains a 2.26.06 series which is supposed to work with newer kernels in fedora but I couldn't get them to work. The current update version of the kernel for RHEL4 contains version 2.26.04.010 of the module. If the next kernel update included 2.26.05.006 or a later version of the 2.26.05 series, then as far as I know, this bug would be closed.
Background that I've learned so far about this 3ware card: This new model (Installation Guide dated Oct 06) is not an incremental updated version, it's a version for pci-express where the next older model is for pci-x. I assume that this explains why the older driver isn't compatible; the connection bus is different. 3ware claims that their cards provide the highest capacity and performance, and best raid 6 performance. They might be accurate, I checked adaptec to see if they had a product I could purchase to work around the lack of driver problem and the biggest card they had was 8 ports with discrete cables (my server has 16 bays) wheras the 3ware product has 16 ports with 4 quad cables (their invention they say). They claim the write performance hit from raid 6 over raid 5 is only 15% with their cards (as opposed to 60% with others). The only problem I have with their product (since I got the driver to work) is that the management tool is not open source, boo. ( It works good though. )
