@Fritz here's how to dump the bios
Code:
./Linux_x86_64/Yafuflash -nw -u admin -p admin -ip 192.168.1.100 -bios -dump v4bios.bin
Change username/password/IP to the BMC ip/credentials, host must be powered off
you can't dump the ipmi, but that should be fine because that worked before. Also, if you're able to liveboot a linux cd, could you also run lsscsi -g, and show the output? (Or storcli /c0/e0 show) and show the expander part?
Curious to see what your expander firmware version is as well. Either way, I've got 2 jacked up chassis now, since I tried to perform the udpate once more on the other expander... FML
