I recently swapped my chassis from a Chenbro RM23612 to a Supermicro SC846E for more room and better thermal. However, it seems like that the backplane in the Chenbro was direct attach and Supermicro is expander type. Both ran on 3 Mini-SAS cables to my 2 M1015 in IT mode. I expected the switch to cause some problems, but after I had everything installed and plugged it, it booted up and loaded FreeNAS to my surprise. Although, I am now seeing these errors in the bootup process that I am wondering I need to be concerned and if I can do anything to get rid of them.
