Very strange. Thanks for testing FreeBSD 10. The problem seems to be that the driver thinks that the controller is NOT in JBOD mode. There’s special code to hide component members in RAID mode; it changes the first byte of the inquiry response to 0x1f. That change indeed shows up in the results that you gave me. I don’t see any significant changes in the ciss driver between 10.x and 11 that would explain why one driver detects the card mode and the other does not.
