title: Linux low level driver - how to receive multiple commands for a device
body: <p>I had written a linux scsi low level driver for cdrom. Am able to receive commands one by one from application and am testing it using sg3-utils. </p>
  
  <p>Now I want to receive more than one command while serving the first one.?
  for this I tried changing the struct scsi_host members can_queue and cmd_per_lun to some big values like 40, even though not able to receive multiple commands.</p>
  
  <p>Is there any way to test multiple command reception in existing drivers like scsi_debug ?</p>
