Then the 3Ware card must not be doing something that a
typical SCSI card does, and more typical of a "dumb" block
ATA driver, even though it's using the SCSI subsystem.

Again, SCSI cards must have some added notification, or at
least the ones you are using. I guess that would make sense,
because there _is_ the "host adapter" on-board.
In any case, 3Ware cards do _not_ do it for JBOD.
