Anyone get LSI SAS drivers to load properly?
I've been fussing with this fine piece of hardware (Supermicro MB w/ LSI SAS1068e RAID controller) and have not been able to get the drivers to work w/ a trial install of RH EL 5 (2.6.18-92.el5). The OS is installed and happy on two SATA drives, but the RAID array--composed of my expensive SAS drives :-( --is invisible (fdisk doesn't list it).
I've got the RH 5 RPM available from LSI. (I tried Debian before without success [no luck building from source as guided by someone who knew how to do it] but I think I may have had the wrong version of the source--it built but the drivers wouldn't load.) I decided to try RH because there was an RPM available:
LSI's Downloads for 1068 controller
The latest stuff from LSI seems to be version 2.6.18-53 (loading the RPM apparently created several directories in /lib/modules) while the balance of the stuff in /lib/modules is under 2.6.18-92.el5 (I don't know if the version number in the paths to the drivers [2.6.18-53] means the kernel won't find them, but I'm assuming that might be so--I'm a DB guy so I'm beyond my knowledge here). The RPM loaded up fine but the /etc/init.d/fusion.mptctl service doesn't want to start (I get this error as part of the startup as well as when attempting manually it after bootup):
How do I find any error log entry there may be? (Nothing seems to show up in /var/log/messages.)
Can I just copy the /lib/modules/2.6.18-53.el5 files into the /lib/modules/2.6.18-92.el5 directory (and maybe they'll work)?
Do I need to recompile from source for the particular kernel version I'm dealing with? (If so I'll have to find/hire someone to help with that!)
Any suggestions most gratefully accepted!
Got the arrays recognized.
OK. Although I was unable to get the mpt LSI drivers to load, I was able to find drivers that did work (they were already installed--I assume by Red Hat).
Here's what worked (flailing around to arrive at the relatively simple fix omitted!):
Rebooted and now I can see the SAS RAID arrays as devices via fdisk -l.
cannot load LSI SAS megaraid on Fedora 9 installation
Hey, glad to see somebody who did it. Mine is on Fedora 9 installation. Here's my thread: http://www.linuxquestions.org/questi...8/#post3202806
Can you share with me how to solve this? Thanks so much.
Sorry not to be any help, EW. All I know is what worked for me.
Just BTW, when I upgraded to the next kernel: 2.6.18-92.1.10.el5, I lost access to the SAS drives again.
Here's the very terse and unhelpful reply I got from Supermicro support:
Corrections and final notes
(In case anyone comes looking for info on LSI 1608-based controllers to get an older box working.)
The megasr driver that worked for me is from LSI. It's closed source (as of this writing).
Check out the reply too this thread labeled "Current State of Affairs ..." (it's probably at the very end of the thread--as I don't expect anyone else will post to it):
