James,

You confused me with this - my testing with 2.4 seems to indicate that
SCSI won't queue up more than one command per LUN (that is, it waits for
one command to complete before issuing the next). How can I tell it to
do otherwise? (It allows parallel commands, as long as they are going to
different LUNs). I didn't see anything in the SHT to indicate otherwise.
