Unkillable processes are an indication that the process is locked in kernel. (Signals are only checked -- and thence acted on -- when processes exit the kernel.)

So you have to reset the device driver in the kernel. If you're lucky it's a module, so just yank the module:

lsmod | grep scsi
rmmod $whatever

Beyond that, perhaps you could reset the physical device. Pull out power or data cables, that sort of thing. Easier of course if it's externally mounted.
