1) Has anyone been able to get their AIC-9410 controller recognized in CentOS 5.3?
I'm working with a Supermicro X7DBR-3 motherboard. It has 2 "ICH Raid Codebase" options in the Bios (Intel and Adaptec); neither of which seem to change Linux's behavior. The interesting part though, choosing either Adaptec or Intel, then performing an 'lspci' always displays "Intel Corp 631xESP/632xESP SATA RAID Controller (rev 09)".
I've seen several people post on a variety of mailing lists (typically using older CentOS revisions), but it doesn't appear many were successful. It seems most swap to software raid.
2) When using this internal host raid controller, shouldn't the raided devices appear as a single device like other traditional scsi controllers?
Regardless of the raid options I choose, Linux still continues to see both drives (/dev/sda and /dev/sdb). Is this a function of being 'HostRAID'?
3) If you've been able to get it to work, which driver did you use?
Thus far, I've tried 2 drivers.
1st driver: adpahci -- Unsuccessful
I downloaded it from supermicro's website. ftp.supermicro.com/driver/SATA/Adaptec_ESB2/Linux/Redhat/adpahci.rhel5.i686.img
After successfully loading the image and inserting the module using kickstart, nothing useful happens, other than several /sys entries added. (NOTE: I had to change the internal cpio archive pathing from `2.6.18-8.el5' to `2.6.18-128.el5').
2nd driver: aic94xx -- Unsuccessful
The driver is built-in via a patch to the Redhat stock kernel.
Other than saying that it's loaded, it also does nothing useful outside of /sys entries. Several mailing lists and documents pointed to using the 'attach_HostRAID' option, however, it doesn't exist. Using this option with `insmod' (or modprobe) fails.
3rd driver: adp94xx -- In the works
I downloaded this driver from Adaptec's website: http://www.adaptec.com/en-US/speed/sas/linux/adp94xx-1_0_8-12_src_tgz.htm
So far, I'm not able to get it to compile because I'm trying to create a patch file so that it incorporates all of the contents of the tarball.
Any ideas on where to go from here? I'd really like to avoid software raid.
Thanks, Kurt
