The LSI driver breaks mfiutil however, so make | sure you have megacli or the like working. | | Xin Li is looking at merging support for the 9240 into FreeBSD mfi, but the | two have diverged so it's not a slam-dunk. You should have Xin have Scott and myself review changes. However, LSI sent me changes (a relative long time ago) to integrate. I need to go through them, test them and have them reviewed. The version on their web site had some concerns and I don't know if this card is one of them. I should be getting back to doing some real FreeBSD work at work but been busy with other work. There are a few things I need to get back into FreeBSD. Hopefully LSI didn't give up on me. Atleast iXsystems was able to off-load some work for me via graid etc. I've been helping to get them to converge versus diverge. However, what is put on their web site can be an early version of work. It's great that LSI is supporting FreeBSD. So far any LSI MegaRAID SAS card that I've tried has worked. I don't have all of them but might be able to get some now from LSI. It might be good in the future to convert mfiutil to use the LSI ioctl. It should be fairly trivial to do our in-house tool uses the LSI ioctl. Users need to understand that their SAS cards are different then their RAID cards. That can usually be figured out looking at Linux references. Thanks, Doug A.
