ciss(4) HP Smart Array P840

[Scott Long]

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.

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.
