Hi jonathon, Like Sean, I haven't worked on the driver in years, so my knowledge is rusty= . If you want to dig around in the code, you could try disabling the 'fixup= ' function in sys/deb/ciss/ciss.c that gets called on command completion.

Thanks for testing FreeBSD 10. The problem seems to be th= at the driver thinks that the controller is NOT in JBOD mode. There=E2=80=99= s special code to hide component members in RAID mode; it changes the first b= yte of the inquiry response to 0x1f. That change indeed shows up in the res= ults that you gave me. I don=E2=80=99t see any significant changes in the c= iss driver between 10.x and 11 that would explain why one driver detects the= card mode and the other does not.
