after searching the SDB as well as other sites such as http://www.linux-ide.org/ and http://tldp.org/HOWTO/HOWTO-INDEX/howtos.html and even https://listman.redhat.com/archives/ataraid-list/2002-September/thread.html I am really confused. I have a SIIG ATA 100 RAID controller which according to SIIG is a hardware RAID. SIIG tells me they don't support Linux. http://www.linux-ide.org/chipsets.html leaves me wondering if the Linux support for the CMD 649 is only soft raid. Can anyone confirm this? If the support is hard raid, I am lost because all the links I find are for setting up soft raid. 1. is Linux support of CMD 649 chipset hard or soft raid? 2. can someone point me to useful instructions that apply to whatever support this chipset has in linux? Assuming that it is soft raid, does http://tldp.org/HOWTO/Boot+Root+Raid+LILO-4.html give a good way to turn a single drive non-raid setup into raid1 two drive setup? 3. in the case of question 2, does it matter if I am using GRUB? 4. does the default SuSE 9.0 kernel require the 0.90raid patch mentioned in 4.1 of the above HOWTO? I would really appreciate any help provided. Thanks Damon Register

Sigh. These cheap-o storage controller manufacturers decided to take their IDE controllers, add array setup and boot support, and call it "hardware" RAID. The RAID functionality is still performed entirely in the operating system so normal people consider it software RAID. If you want *real* IDE RAID, you'll want 3Ware. They have the only *real* IDE RAID controllers I am aware of. (If anybody knows of any others, feel free to correct me) You could also use one of the many SCSI RAID controllers that are available. - -- James Oakley Engineering - SolutionInc Ltd. joakley@solutioninc.com http://www.solutioninc.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) iD8DBQE/0I8a+FOexA3koIgRAuZ4AKCqNLEjUyRG70fhapO//oNOexs8bACgkqwr j0UT2eA3VkVFL5ldGSYQI+U= =8Idu -----END PGP SIGNATURE-----

You could also use one of the many SCSI RAID controllers that are available. I like SCSI best but I can't afford that now. This is just a small setup for home and I have limited funds. I was lucky enough to get one IDE drive for a birthday present and the second with some bonus points that I had built up with Best Buy.
So in order to work with what I have, I can follow soft raid directions? In step 4.1 of http://tldp.org/HOWTO/Boot+Root+Raid+LILO-4.html am I correct in thinking that SuSE 9.0 doesn't need the downloading and patching but only needs the kernel recompile? Does anyone know if this procedure is compatible with GRUB? Damon Register
