We have X8DTH-6F and it was generating errors in Linux. They are running CentOS 6. We updated the BIOS. No change. Then we updated the LSI firmware. The LSI controller is now not recognized by CentOS. We ended up having to connect the drives to the SATA ports to get it to work. Do you know if there is a compatibility issue between CentOS and the latest LSI Firmware?
Please make sure to load correct driver for 6.0 to get it detected:
