+ * 2) If one number comes after the device name (,sid) it is the
+ * SID; controller is set to -1, lun is set to 0
+ * 3) If two numbers come after the device name (,sid,lun), they are
+ * the SID and LUN; controller is set to -1
+ * 4) Three numbers after the device name are all three number fields.
