Dell Poweredge R300 Fails On LSI SAS 1068e "Raid" card

[Damian]

Hi all,

We’ve got fog up and running happily for our enterprise but I’m having trouble imaging one of our servers. Despite a reference to our raid card in the “working hardware” section of the wiki, I can’t seem to get the thing to show me any hard disks.

I rebuilt the kernel including support for the mtpsas devices as it appears that this is what I need to do. Also, if I boot a live linux (Ubuntu 10.04) it recognizes the disks and doesn’t seem to have a problem.

The best I can figure is that there is a kernel module being loaded dynamically by the live linux that isn’t available in the source that I’m building. Does anybody have any experience with this card or server? Also, is there any way to get dynamic modules to be loaded by the target machine that is being backed up. Can I send a kernel module along with the bzImage and then instruct the system to load it (modprobe)?

load the live disk and list the modules with lsmod. This may help you find all the drivers you need to compile into the kernel.

Here is some info on the R200 series servers that might help with the disk issue.

Hey,

Thanks for the response. I bailed on the server for the time being. In some of the other work I’ve been doing I found that including other modules into the image is pretty easy. I just needed to run

/opt/fog/utils/Boot Image Editor/FogMountBootImage.sh

This should let me place the modules that I need (once I identify them) into the image so they are available when fog loads. I haven’t tried it yet but when I do I will come back and update this thread.

Thanks
Damian
